Why Does My Furnace Smell When I First Turn It On?

After waking up to a particularly cool home on a September morning, you switch on your furnace and notice an unusual odor. While it’s sometimes normal to experience furnace smells when it’s first turned on, there are specific odors that indicate a problem. At Elkhorn Heating, Air Conditioning, Plumbing & Electrical, we can quickly diagnose your unusual odor and determine if it’s dust settling on the unit or something else.

If you smell gas, immediately evacuate the area without operating electrical switches or electronics. Once you are safely outside, call your utility provider’s emergency line or 911. Similarly, if you see smoke or fire, evacuate and call 911 before performing any of the following checks.

What the Different Odors May Mean

When dealing with furnace odors in Denver, it helps to consider the type of smell and when it occurs. While the odor description provides a strong clue about what is going on, it is not a diagnosis. For professional diagnostics, reach out to our experienced Comfort Specialists.

The following are some of the most common smells you may notice.

Mild Dusty Odor

If your heat smells like burning dust when it first starts up, that is probably exactly what the odor is. This is especially common at the end of fall and beginning of winter. Dust builds up in the furnace as it sits unused over the summer, leading to a furnace burning smell during the first use of the season. If this is the case, the smell should go away in a few minutes.

Persistent Burning or Plastic/Electrical Smells

A temporary burning odor at startup might not be an issue, but it’s an immediate concern if it doesn’t go away. Ongoing burning, hot plastic, or electrical smells can occur if the electrical components are overheating. Because of the potential fire and electrocution risks involved, you should immediately shut off your unit and call for repairs.

Sulfur or Rotten-Egg Odors

This is another smell that requires immediate action. Natural gas contains an additive that smells like rotten eggs so that it’s easier to detect leaks. If you notice a sulfur-like smell, there may be a gas leak in your system. You should immediately evacuate your home. Once everyone is in a safe area, call 911 or your gas utility’s emergency line.

Musty Scents

If your furnace produces a musty smell, it may be due to mildew or mold growth in your ductwork, vents, or blower compartment. To protect your family’s indoor air quality (IAQ), you should schedule an IAQ assessment and furnace inspection.

Carbon Monoxide Leaks

Carbon monoxide (CO) is an odorless, colorless gas. Because of this, you won’t be able to detect dangerous carbon monoxide from your furnace by smell. Even if your furnace does not produce any odor, you should schedule seasonal tune-ups to inspect the system for combustion, venting, and other safety issues. Additionally, test your home’s CO alarms monthly, replace batteries as needed if they are replaceable. You should also replace the alarms according to the manufacturer’s recommended service life.

Possible Causes Behind a Startup Smell

If a furnace smells when first turned on, there are several potential causes that could be responsible. Dust on heating surfaces, restricted airflow, overheating, electrical malfunctions, and motor problems can cause this symptom. 

While dampness, mold growth, and contamination are possible reasons for musty odors coming from your vents, they are not the only potential cause. Because of this, you should always have your system evaluated by a professional. The smell alone will not be enough to diagnose which part failed.

What Homeowners Can Safely Observe

As a homeowner, you should not do any troubleshooting if you hear an alarm, notice smoke or fire, or suspect gas. If it is safe to do so, you can use the following steps to safely observe the issue and rule out a few basic causes.

  • Note when the odor occurs and any airflow or noise issues. Pay attention to whether it fades and returns.
  • After turning your equipment off, you should inspect the filter and replace it with the correct type. 
  • Check the return vents to see if they are blocked or obstructed. Do not open any equipment panels to do so.
  • Never restart equipment repeatedly to reproduce the odor. You should also never clean burners, open the cabinet, test wiring, or adjust gas controls yourself. 
  • Do not spray fragrance or cleaners into the vents. This will not fix the problem. 

After completing these basic checks, you can reach out to our team for a full diagnostic if the problem has not gone away.

When To Call for Service or Emergency Help

While a furnace smell after summer is sometimes a normal symptom, there are situations where emergency help may be needed. To protect your furnace, family, and home, use the following emergency response steps if you notice any concerning symptoms.

  • Persistent, Unidentified Burning: In this situation, you should immediately stop the system if it is safe to do so. Do not keep operating it to see what happens. Once the unit is off, reach out for emergency repairs.
  • Suspected Gas: If you suspect a gas leak, leave the area right away. Do not try to operate electrical switches, adjust the thermostat, use your phone, or do anything else that might cause a spark. Once all of the home’s occupants are at a safe outdoor location, you should call your gas utility’s emergency line or 911. Never try to find the leak yourself. Additionally, do not delay leaving in order to ventilate.
  • CO Alarm or Suspected Exposure: If a CO alarm goes off or you suspect CO exposure, have everyone evacuate your home. Then, call 911.
  • Smoke or Fire: For smoke or a fire, you should evacuate all of the home’s occupants. Then, call emergency services. Do not allow anyone to go back inside until emergency responders confirm that your home is safe.

After you have completed the appropriate steps, you can contact our Comfort Specialists for professional help. One of our technicians will come to your home to inspect your unit’s airflow, electrical condition, combustion, and overheating. Then, we will provide a no-pressure recommendation for solving the problem.

Frequently Asked Questions

Is a dusty smell normal when the furnace first starts? 

If your heater smells like burning dust when you first start it, the odor will likely go away. This type of odor can occur after downtime. After a few minutes, the dust buildup will burn off, and the odor should go away. If the odor remains, worsens, or is unfamiliar, you should have your furnace looked at by a professional.

How long should I wait for a furnace smell to go away? 

There is no universal waiting period for unusual odors. Instead, you need to consider what other signs are present and the type of odor. If you are unsure about the cause of the smell, you should reach out for help instead of waiting for the odor to go away.

What if my furnace smells like burning plastic? 

When a furnace smells like burning plastic, it may be due to overheated or melting electrical insulation, debris in the ductwork, or a faulty electrical component. No matter what the cause is, you should stop using the furnace if it is safe to do so. Then, immediately call for an inspection. 

Any indications of smoke, a fire, a CO alarm, or gas should be treated as an emergency. In this situation, you should immediately leave the area and call 911 or your utility provider.

Can I smell carbon monoxide from my furnace? 

No, you cannot. CO is an odorless gas, which is why homes have CO alarms installed to detect it. If your alarm goes off, you should immediately go outside and call emergency services. Do not try to investigate the problem or fix the furnace yourself.

Dual-Fuel Heating in Denver: How a Heat Pump and Furnace Work Together

As fall gets underway in Littleton, it helps to plan ahead for sustained heating demand in the winter. Dual-fuel heating in Denver offers a strong balance of efficiency and performance during our cold winters, although it might not be the right choice for everyone. At Elkhorn Heating, Air Conditioning, Plumbing & Electrical, we can help you determine if your home can work with a heat pump and furnace combo.

What a Dual-Fuel Heating System Includes

With dual-fuel heating in Denver, an electric heat pump and fuel-burning furnace are set up to work together. The fuel-burning furnace, which often uses gas, is designed to take over at colder temperatures when the system determines it is more appropriate or cost-effective than the heat pump. Meanwhile, the heat pump offers a comfortable year-round heating and cooling option for less extreme weather conditions.

Heat pumps rely on refrigerant to transfer heat from one area to another. Known for their energy efficiency, these units are able to transfer heat outdoors in the summer and indoors in the winter. In comparison, furnaces are known for delivering a powerful source of heat on the coldest days of the year. Together, these heating, ventilation, and air conditioning (HVAC) systems can offer a mixture of comfort and energy efficiency.

A dual-fuel system includes a few key components.

  • Electric Heat Pump: A heat pump is designed to transfer heat with the help of refrigerant lines, a compressor, an outdoor condenser coil, and an indoor evaporator coil. 
  • Fuel-Burning Furnace: Propane and natural gas furnaces create heat through a process known as combustion. The burner combusts the fuel, while the heat exchanger transfers the resulting heat to the air moving through the system. Dual-fuel systems are designed to switch to the furnace when it becomes more cost-effective.
  • Indoor Coil and Blower: The indoor coil transfers heat between the refrigerant and indoor air, while the blower moves conditioned air through your home’s ductwork and vents.
  • Compatible Controls: With a dual-fuel system, the unit must be set up with compatible controls that determine when it switches from using the heat pump to using the furnace. While there might be two systems present, the heat pump and furnace are not designed to heat your home at the same time.

Some heat-pump systems include auxiliary electric resistance heat strips in the indoor unit that can operate during defrost mode or when additional heat is required. These resistance strips are not the same as a fuel-burning furnace setup. Resistance strips are not meant to run all the time, and they can quickly increase your energy bill.

How the System Decides When To Switch

Once your furnace and heat pump are set up, one of our Comfort Specialists will configure your controls and set up the automatic changeover temperature. With most dual-fuel systems, the changeover temperature is the outdoor temperature at which your system automatically switches from your heat pump to your furnace.

There isn’t a single correct changeover temperature for every situation. Instead, it is important to consider the cost of both fuel sources, the equipment limits, installer configuration, and your family’s comfort needs. 

While some controls can automatically track current utility prices and adjust accordingly, others use a fixed outdoor threshold. For example, your system may be set up so that your heat pump runs during a mild day in Littleton. Then, the system can switch over at night as the temperature drops.

Once we’ve installed your dual-fuel system, we can set up a changeover point. Later on, you can adjust this point until it matches your family’s comfort and energy preferences.

Is It a Fit for Your Denver or Littleton Home?

While there are many advantages to dual-fuel heating in Littleton and Denver, there are also drawbacks to consider. Before installing any system, an experienced HVAC technician will need to review your home’s insulation, heat loss, duct capacity, duct leaks, and electrical supply. They will need to evaluate your existing furnace to see if it can be kept. In addition, your home must have enough space available for the new installation. 

An existing furnace may be kept if it is in good condition, appropriately sized, and compatible with the necessary coil, blower, and controls. Alternatively, homeowners could set up a cold-climate all-electric system instead of installing a dual-fuel system. There are multiple heating options you can use, so talk to an HVAC technician about all of your options before making a decision.

As a homeowner, it is also essential to remember that all modern HVAC options are going to require electricity. Even natural gas and propane furnaces use electricity to operate the blower and controls. While installing a dual-fuel system offers a number of benefits, it cannot work as an automatic heating backup during a power outage.

Installation Costs and Operating Tradeoffs

Before deciding on any system, you will also need to consider the installation costs and operating tradeoffs for each choice. The cost of a dual-fuel system can vary widely based on whether compatible equipment can be reused and if other duct, electrical, or control work is needed. 

Besides the upfront purchase costs, it’s also worth considering the operating costs, financing costs, and incentives. Specific systems may qualify for incentives from the state, municipalities, or utility providers, but the availability of these programs can vary greatly.

As part of the operating cost comparison, you should look at the current rates charged by your electricity and fuel providers. Then, consider your home’s typical use, furnace efficiency, and heat loss. By comparing all of these factors, you can determine if getting a new system makes financial sense.

Questions To Ask Before Installation

Before you install a heat pump with a gas furnace for backup, there are a few important questions you should ask.

  • Was a heating and cooling load calculation performed? 
  • What heating capacity will the heat pump provide at our local winter design temperature?
  • Can I keep my existing furnace and ducts? 
  • How do I set the changeover temperature? What controls are necessary?
  • Will I need electrical or venting work for the upgraded system?
  • What type of commissioning tests will you perform to confirm that everything is set up properly?
  • Can I have an itemized scope of work that includes all of the warranty terms?
  • What incentives am I eligible for? 
  • How do I maintain my system? How often should I schedule tune-ups?
  • What would an alternative setup, such as just a heat pump, cost? 

Frequently Asked Questions

Can I keep my existing furnace when adding a heat pump? 

It depends on the furnace’s condition, sizing, compatibility, and controls. Our Comfort Specialists will perform a full assessment to determine if your existing furnace can be reused. Newer, well-maintained furnaces that are compatible with the new equipment are more likely to be retained than old, poorly sized, or incompatible furnaces.

At what temperature does dual fuel switch to the furnace? 

There is no universal setting where this occurs. It depends on your home heat demand, equipment performance, energy costs, and controls. You can generally adjust your thermostat to change the point where this occurs. We generally recommend monitoring your new setup for at least a few weeks so that you can assess its comfort and performance. If adjustments are needed, your thermostat settings or system controls can then be fine-tuned incrementally until you find the right balance of comfort and efficiency.

Does dual-fuel heating work during a power outage? 

Unfortunately, no. Modern furnaces and heat pumps rely on electricity. Even if you have a propane or natural gas furnace, it will still need electricity to run.

Will dual fuel always lower my heating bill? 

Not always. It all depends on utility rates, home heat loss, overall performance, and how you use the system. Because utility costs can vary, you should have a home-specific energy comparison before installing a hybrid heating system.

Furnace Starts Then Stops? Why It Won’t Stay Running

After a particularly cool morning after months of cooling use, you switch your thermostat to “heat” mode to take the chill off. Instead of running smoothly, the furnace starts, then stops. When this happens, the culprit could be the unit’s airflow, flame proving, controls, or safety mechanisms. By understanding common causes and signs of each issue, you can determine when you can troubleshoot yourself and when you should reach out to Elkhorn Heating, Air Conditioning, Plumbing & Electrical for help.

What Exactly Is Starting and Stopping?

When a furnace starts then stops, a few things could be happening. As a homeowner, it’s useful to note whether there is ignition followed by flame loss, repeated attempts without ignition, several minutes of heat followed by a shutdown, or the blower continuing to operate after the burners are off.

How you respond to the problem will depend on the symptom you’re experiencing and the cause. For instance, the blower will normally run slightly longer than the furnace to remove residual heat. If the furnace keeps shutting off and your home doesn’t reach the set point, there is likely an underlying issue responsible. 

To make the diagnostic process easier, you should start by noting which signs are occurring. For example, pay attention to unusually frequent or brief on-and-off cycles. This is known as short cycling and can provide a clue about what’s going on. You can also look through the existing viewing window if it’s safe to do so without removing panels. Flickering flames, a lack of a flame, and unusual noises are all strong indications of the problem.

Common Reasons a Furnace Will Not Stay Running

When a furnace won’t stay running, there are a few possible causes that may be at fault. By understanding the common causes, you can determine whether basic maintenance will solve the problem or professional repairs are necessary.

Restricted Airflow and Overheating

If your unit’s airflow is restricted by a dirty filter, blower speed issues, ductwork problems, or blocked returns, it can cause overheating and high-limit trips. A tripped high-limit switch doesn’t necessarily mean the switch is bad. Often, this occurs because the system is too hot. Many of these airflow issues can be prevented or detected early by scheduling routine maintenance appointments.

Interrupted Flame Proving

A flame sensor is responsible for detecting whether a flame is present after ignition. If the sensor doesn’t prove the flame, the control board shuts off the gas valve to prevent unburned gas from continuing to flow. Because of the gas and combustion involved, you should leave sensor inspections and cleaning to an experienced technician.

Ignition Faults

Dirty pilot assemblies, cracked hot surface ignitors, and weak spark ignitors can all result in failed ignition. Depending on the ignition system, you may hear repeated clicking, see that a pilot fails to ignite, or notice that the burners never light. Multiple ignition failures can lead to a system lockout.

Thermostat Commands

Dying batteries, loose wiring, and incorrect settings can cause thermostat problems. For instance, the system may ignore thermostat commands or cycle on and off frequently.

Venting or Condensate-Related Safety Responses

With high-efficiency furnaces, blocked PVC intake and exhaust flues or clogged condensate traps can mean that the pressure switch fails to close. This triggers a safety shutoff. An accessible obstruction at an exterior intake or exhaust termination may be safely cleared, but persistent pressure-switch or condensate problems require professional diagnosis.

Equipment Sizing

Before installing a heating, ventilation, and air conditioning (HVAC) system, the technician should always perform a Manual J load calculation or an applicable existing load calculation. If your furnace is oversized for the home’s heating load, it may satisfy the thermostat quickly and operate in shorter, more frequent cycles. For homeowners, the furnace will appear to cycle on and off quickly.

However, equipment sizing isn’t a new issue. If this is the problem, you’ll likely notice that the furnace has relatively short cycles soon after it is installed.

Safe Checks Before Scheduling Service

Before you call for assistance with a furnace that turns on then off, there are a few basic checks you can safely do on your own first. For your safety, you should never perform repeated resets, remove the panel, bypass the safety switch, clean the flame sensor, test live electrical systems, adjust the gas, or reach inside a running unit.

  • Confirm the Mode: Verify that the unit is in “heat” mode. It should have a sensible set point that is above room temperature. The schedule should be set to the appropriate temperature as well. 
  • Check Batteries: If your thermostat uses batteries, check the batteries and replace them as needed.
  • Inspect the Filter: After turning the equipment off and consulting the manufacturer’s guide, inspect the filter. If it is clogged, replace it with the appropriate size and MERV rating. Never run your unit without a filter in it.
  • Clear Furniture From Registers and Grilles: Move any furniture, clothes, curtains, or other belongings away from the supply register or grille.
  • Observe Moisture Sources: Pay attention to any standing water or moisture in or around your unit.
  • Note the Thermostat Display: If your furnace keeps shutting off, try checking the thermostat display to see what mode the unit is in and if any error codes are visible.

When To Stop Troubleshooting and What a Technician Checks 

If your furnace short cycling continues and basic troubleshooting doesn’t solve the problem, it’s always a good idea to reach out for a professional inspection. You should also immediately call for help if you experience any of the following situations.

  • Your home has no heat in cold conditions, especially if vulnerable family members are present.
  • You experience furnace short cycling in Denver that continues after basic troubleshooting.
  • The furnace keeps experiencing safety shutdowns.
  • There is a gas odor or the carbon monoxide alarm goes off. If this occurs, first leave the building. Then, call your gas utility’s emergency line or 911 once you are safely outside. Afterward, you can call our Comfort Specialists for repairs.
  • Immediately evacuate the premises and call emergency services if you notice signs of smoke or a fire.
  • If you notice repeated ignition failures or flame loss shortly after ignition, stop troubleshooting and call for repairs.
  • You noticed unusual noises, such as booming, grinding, or screeching sounds.

Once you reach out to our team, we’ll quickly run a series of diagnostics to determine the problem. We’ll check the flame signal, airflow performance, ignition sequence, draft and venting, condensate line, temperature rise, and thermostat commands. Through our testing, we can figure out the best solution to your heating issues.

Frequently Asked Questions

Why does my furnace shut off after a few seconds? 

If the ignition is interrupted or the flame sensor doesn’t sense a flame, your furnace will shut off after a few seconds. Because you can’t diagnose a sensor issue from duration alone, it’s important to schedule professional testing if your furnace experiences repeated failures.

Is it normal for the blower to keep running after the heat stops? 

Many furnaces are designed with a short fan delay that keeps the fan running to safely cool down the heat exchanger and optimize energy efficiency. If the blower remains on for an unusually long time, check whether the thermostat fan setting is set to “on.” If it is set to “auto” and the blower continues running, the furnace may have experienced a fault or safety condition that requires diagnosis.

Can a dirty filter make my furnace turn on and off? 

Yes, restricted airflow can cause overheating and safety shutdowns. If replacing the filter doesn’t resolve the issue, call for professional repairs.

Should I keep resetting a furnace that will not stay on? 

No. Repeatedly resetting the furnace can override opportunities to recognize an ongoing fault or safety problem. You should note any error information or symptoms. Then, relay this information to the HVAC technician when you schedule professional diagnostics.

Half the House Lost Power After a Storm: What Could Be Wrong?

If half the house lost power after a storm, there are a few different causes that could be at fault. While a GFCI or breaker issue is relatively easy to fix, panel damage, unsafe wiring, and utility-side issues require professional help. At Elkhorn Heating, Air Conditioning, Plumbing & Electrical, we can help with electrical problems due to lightning, wet outdoor outlets, utility interruptions, and other issues.

Quick Answer: Why Only Half the House May Lose Power

When you have a partial power outage after a storm, you’re most likely dealing with one of the following issues. How you respond to an outage is going to depend on the reason why it happened.

  • Tripped breaker
  • GFCI/AFCI trip
  • Damaged circuit
  • Utility service leg problem
  • Surge damage
  • Panel issue
  • Wet exterior device

Anytime only half the house loses power after a storm, you should always exercise caution because some of the potential causes can involve unsafe voltage, damaged wiring, and potential fire hazards.

Important Safety Note: For the safety of yourself and your home, you should never open the electrical panel or touch wet electrical equipment. If there is water near any electrical components, you should call for professional electrical services.

First Safety Checks Before Troubleshooting

Because of the dangers involved with electrical systems, there are a few safety checks you need to make before you can safely do any troubleshooting.

  1. Check for burning odors or sparking.
  2. Note any hot devices, warm outlets, or damaged outdoor wiring.
  3. Look for visible water intrusion, but do not touch any wet electrical systems.
  4. Stop and call for electrical service if any of the previous warning signs are present.

Depending on how these safety checks go, there are several additional steps you may need to perform. If your neighbors are also without power, report the outage to your utility provider. 

When you call for service, you should accurately describe the problem. Note any essential loads, medical devices, or refrigerators affected so that our team can understand the urgency involved.

Simple Causes Homeowners Can Check Safely

So, what do I do if half my house has no power? Once you’ve determined that your home is safe, you can use the following steps to troubleshoot. If these solutions do not work, you’ll need to reach out to our Comfort Specialists for a full electrical evaluation.

  • Check your breaker panel for tripped breakers. If a breaker is sitting between the off and on position, you can reset it once. For repeated trips, call for repairs.
  • When water is present near a GFCI outlet, it can shut off power to your bathroom, kitchen, garage, basement, or outdoor outlet. To avoid safety risks, moisture intrusion requires a professional inspection.
  • An AFCI breaker may trip due to storm-related arcing or problems with the device. You can reset the breaker once. Schedule repairs if it keeps tripping.
  • A plug-in surge protector or power strip may fail after a surge. After checking for damage, you can try resetting these devices.
  • Moisture damage, downstream loads, and wiring errors can cause GFCI outlets and breakers to trip. If these issues are present, they’ll need to be addressed by an electrician.

While you can reset a breaker or outlet once, do not continue to reset it if it keeps tripping. Repeatedly tripped breakers and outlets likely have an underlying electrical problem that must be addressed before the circuit can be used again.

Storm-Related Electrical Problems That Need a Pro

While homeowners can perform basic troubleshooting on their own, more complicated issues should be handled by a professional. If some rooms have lost power after a thunderstorm and you experience any of the following issues, call our team right away.

  • Utility Service Leg Problem: In a typical 120/240-volt residential service, each leg supplies approximately 120 volts. If one service leg is lost, circuits on that leg may lose power and 240-volt appliances may stop working properly.
  • Panel or Breaker Issue: Any buzzing noises, corrosion, warmth, or repeated trips are signs that you should schedule a breaker panel inspection right away.
  • Wet Outdoor Outlets, Exterior Lighting, GFCI Devices, or Damaged Wiring: Following wind-driven rain, there may be moisture inside your home’s electrical components. You should never try addressing electrical problems at all if there is any moisture involved.
  • Surge Damage: After a power surge, your appliances, smart devices, garage doors, control boards, and HVAC equipment can become damaged.
  • Loose Connections: Following power cycling and storm vibration, your electrical connections can become loose. 
  • Damaged Meter Base, Mast, or Service Entrance: If branches fall or there is severe wind, these components can become damaged.

Can Hail Damage Your Outdoor AC Unit? A Post-Storm Inspection Guide

When wind, hail, and thunderstorm season arrives in Denver and Littleton, the resulting hail dents and condenser damage can quickly impact your unit’s performance. During a heating, ventilation, and air conditioning (HVAC) inspection, Elkhorn Heating, Air Conditioning, Plumbing & Electrical can diagnose damage and help you determine the best course of action.

So, can hail damage outdoor AC units? To learn more, read on.

Quick Answer: Yes, Hail Can Damage an Outdoor AC Unit

Hailstorms are known for denting condenser fins, damaging coil surfaces, bending fan guards, and loosening panels. Leaves and other storm debris can also clog your outdoor unit, reducing its efficiency and leading to eventual repairs.

While cosmetic dents may mar the appearance of your unit, they aren’t the same thing as performance-affecting damage. A full HVAC inspection is important to determine whether your unit is safe to run or requires further service.

What Parts Are Most Exposed During a Storm?

Hail damage to an AC unit in Denver is largely going to occur in areas that are exposed. Often, bent condenser fins and coil damage are the most obvious sources. Part of your air conditioner storm damage may also involve the fan guard, top grille, fasteners, and cabinet panels.

Any electrical disconnects, control components, or exposed wiring near the unit can end up getting loosened or damaged by the storm. Refrigerant line insulation can be harmed by hail. Depending on where the hail hits and how, it may cause erosion, pooling water, shifting of the condenser pad, or drainage problems

Safe Post-Storm Inspection Checklist

Should I run my AC after hailstorms? Before your AC is safe to use, it’s a good idea to complete the following checklist.

  1. Before you do anything, wait until the storm has passed. Do not inspect your outdoor unit until conditions are safe to do so.
  2. Then, inspect for obvious dents. Pay attention to any flattened fins, loose panels, or debris. If the hail blocked the unit’s airflow in any way, you’ll need to schedule repairs before using your unit.
  3. See if hail, leaves, branches, mulch, or any other debris are packed around the condenser.
  4. Listen for unusual noises during startup, such as rattling, buzzing, or scraping sounds.
  5. Note whether cooling performance appears to be affected by the storm.
  6. For your safety and the safety of your AC, never touch wet electrical components, open panels, or push tools into the coil fins.

If you aren’t sure whether hail damaged condenser fins or other components, it’s better to play it safe and get a professional inspection before using your AC again.

Signs Hail Damage May Be Affecting AC Performance

After conducting your outdoor AC unit’s post-storm inspection, pay attention to how your AC continues to operate. If the hail has caused damage, you’ll likely notice some of the following signs.

  • The AC seems to run longer than normal.
  • You notice loud rattling or scraping noises coming from the outdoor fan.
  • The AC struggles to cool your home.
  • Your outdoor unit won’t start. 
  • The breaker trips frequently. 
  • Your AC short cycles, which means it turns on and off more frequently than normal.
  • There are flattened fins or debris blocking airflow through your outdoor unit.
  • You see that hail damaged the cabinet or the line-set insulation.

Reduced airflow isn’t just a cosmetic issue. When airflow around the outdoor unit drops, it affects the condenser coil’s ability to release heat. In turn, this forces your compressor to run for longer than it normally does. Eventually, the added workload can cause the compressor to overheat or break down.

  • Ask a technician if there are safe protective options you can use.
  • Never block airflow while your AC is operating.
  • Schedule a cooling tune-up each spring.
  • Call for maintenance after severe hail, wind, or debris-heavy storms.

One of the most important things you can do to prevent the likelihood of breakdowns and repairs is to schedule routine maintenance. To make this easier, Elkhorn Heating, Air Conditioning, Plumbing & Electrical offers a Whole Home Comfort Plan that features two complimentary tune-ups per year, special promotions, and repair discounts.

Frequently Asked Questions

Can I run my AC after a hailstorm? 

Possibly. Start by inspecting your unit for signs of hail damage. If there are no signs of damage present and it starts normally, your AC may be fine to run. 

However, major dents, debris, electrical damage, unusual noises, and loose parts are signs of potential damage. In these instances, you should turn off your AC right away and schedule service.

Do dented AC fins always mean the unit is ruined? 

No, not necessarily. In some cases, fin damage is mostly cosmetic. Even if the fins do affect performance, our Comfort Specialists may be able to repair them easily.

You may have to replace the unit if there is widespread flattening. In this situation, the damaged fins can restrict airflow around your unit and result in performance-related issues. When our team comes to your home to inspect your system, we can evaluate the impact and help you decide on the best course of action.

What AC damage should I check after hail? 

To avoid performance issues and prevent additional damage, it’s important to inspect your AC after the storm. Without touching the AC, look for signs of flattened fins, loose panels, or damaged line insulation. Pay attention to any signs that the airflow may be blocked. If there are unusual sounds, note what they are to tell your HVAC technician. 

Sometimes, the damage to your AC isn’t visually obvious. After a storm, you should always pay attention to your cooling performance and schedule service if there is a significant change.

Should I cover my AC during hail season? 

While an AC cover can protect your unit from hail, it can also potentially block airflow when your AC is running. Because of this, you should always talk to a technician about safe options before you use a hail cover.

Denver’s 2026 Drought: Indoor Plumbing Upgrades That Reduce Water Use

According to the United States Drought Monitor, 4.7 million Colorado residents are in a drought that covers 91% of the state. In response, the Denver Board of Water Commissioners declared a Stage 1 drought. While outdoor watering rules are in the headlines, indoor water waste is just as important. Leaky pipes, outdated equipment, and inefficient fixtures can all add up over time.

As a homeowner, you can take advantage of a few indoor plumbing upgrades to reduce your water use in Denver. For a full water-efficiency evaluation or installation help, you can turn to Elkhorn Heating, Air Conditioning, Plumbing & Electrical for help.

Start With Leaks Before Replacing Fixtures

Many sources of wasted water likely lurk inside your cupboards and walls. A leaky faucet’s water waste can quickly add up. According to the United States Geological Survey, a single faucet dripping once a second can waste 2,083 gallons of water per year. You can also lose water because of a constantly running toilet, worn shutoff valves, under-sink moisture, and loose supply lines. 

Small drips over time can add up to a significant amount of water wasted. Additionally, they can lead to more expensive repairs and water damage if they aren’t addressed promptly. By repairing your faucets, fixtures, and pipes, you can save on costs over time and lower your water consumption.

Upgrade High-Use Fixtures First 

When deciding on which indoor plumbing upgrades to reduce water use in Denver, it helps to start with your high-use fixtures. Because these fixtures use the most water, a leak or inefficiency will add up more significantly. You will want to update your most frequently used fixtures, such as your bathroom faucets, showerheads, kitchen faucets, and laundry-area plumbing, first. 

In many older homes in Denver and Littleton, the fixtures predate efficiency expectations. As part of your Denver drought plumbing upgrades, you’ll generally want to upgrade with low-flow or WaterSense fixtures.

Low-Flow Fixtures

A low-flow fixture is basically a plumbing component that uses significantly less water than the standard model. You often see this type of option with toilets or showers. For showers, the aerator often mixes air into the stream so that the stream feels full without having as much water. Alternatively, precision nozzles use high pressure to make the flow feel full. 

In comparison, low-flow toilets can use either gravity- or pressure-based systems. A gravity-driven system will use the weight of the water and gravity to flush. With a pressure-assisted system, compressed air is used to powerfully push water into the toilet bowl.

WaterSense-Style Fixtures

WaterSense is a designation from the United States Environmental Protection Agency (EPA) that helps consumers know which products are more efficient. In order to be a part of this program, the product must use at least 20% less water than the federal baseline for its category.

No matter what type of low-flow or WaterSense fixture you use, it’s important to find one that fits your family’s needs. A good fixture should be able to reduce waste without making showers or sinks frustrating to use.

Water Heater Choices That Support Efficient Routines

If you’re trying to figure out how to reduce indoor water use, you may also want to consider your water heater installation. With a traditional water heater, water is wasted while you wait for hot water to leave the hot water tank and travel to the fixture. This wait time can add up if your fixture is especially far from your hot water tank.

To save money on energy costs and water consumption, you could upgrade your home with a tankless water heater. Tankless water heaters heat up water as you need it. If they are installed in or near your bathroom, you do not have to waste water by waiting for your shower to warm up. Because of their size, a bathroom placement is often easier to accommodate.

While tankless water heater water savings can be significant, this option isn’t right for everyone. Its flow rate can only handle so much consumption at a time. If you have an especially large home with many people using water at once, a traditional water heater may be your best option. 

Plumbing Remodels as a Conservation Opportunity 

If you’ve been considering a bathroom remodel, it’s a good idea to consider low-flow plumbing upgrades in Littleton. For example, updated valves, fixtures, shutoffs, supply lines, shower installations, and drains can help you reduce your home’s water consumption. Toilets use nearly 30% of an average home’s water consumption, with old toilets using as much as 6 gallons per flush. WaterSense-labeled toilets can lower the amount used by your toilet by as much as 20% to 60%.

To make your upgrade easier, we recommend considering water-saving plumbing fixtures in Denver at the start of the renovation process. This is especially important if you have an older home that still has its original fixtures. Our team can evaluate your current bathroom plumbing and help you determine which fixtures should be updated.

What Homeowners Can Check This Week

While plumbing renovations are exciting to plan, you won’t be able to completely update your home’s system right away. In the meantime, there are a few plumbing issues you can check this week that can make a difference in your consumption habits.

  • Water Bill: Start by checking your water bill for unusual usage changes. Unexplained increases in water use can help homeowners identify minor, ongoing leaks.
  • Running Toilets: Listen for the sound of the toilet running after flushing. Additionally, immediately call for repairs if you hear the sound of running water when your fixtures are off because this is a common indication of a leak.
  • Damp Spots: Check around the water heater and underneath the sinks for damp spots that mean water is escaping.
  • Showerheads and Faucets: See if your old showerheads and faucets are suffering from mineral buildup. Note if they have shutoff issues.
  • Consumption Patterns: Figure out which of your fixtures are used the most. When you schedule an estimate, you’ll want to prioritize these fixtures.

When To Call Elkhorn

If you notice any of the following symptoms, you should reach out for help right away.

  • There are active leaks.
  • Your home has repeated fixture problems.
  • You notice low water pressure after you change a fixture.
  • There are water heater-related issues.
  • You are planning a future remodeling project. 
  • You have an older shutoff valve.

At Elkhorn Heating, Air Conditioning, Plumbing & Electrical, we offer same-day services, upfront pricing, and no hidden fees. We’re committed to delivering exceptional service, which is why we offer a money-back guarantee. For larger plumbing projects and remodeling upgrades, you can also access convenient financing options.

Frequently Asked Questions

Do indoor plumbing upgrades help during Denver’s drought? 

Yes, they do. When dealing with Denver water restrictions in 2026, homeowners can do more than just limit their outdoor watering. Fixing leaks and updating high-use fixtures can have a major impact on indoor waste. Even when the drought is over, these upgrades can support better long-term habits and lower water consumption.

Which plumbing upgrades save the most water? 

When improving your water consumption habits, it’s important to start with repairing leaks. Then, move on to the fixtures you use every day, such as your toilets, showerheads, bathroom faucets, kitchen faucets, and utility room plumbing. Older fixtures are also more likely to have water-efficiency issues, so it’s a good idea to get these evaluated for a potential replacement.

Should I replace my water heater to save water? 

Not necessarily. There is a balance of comfort, convenience, and efficiency that varies based on your household size and routines. Before you make the decision to replace your water heater, we’ll review your equipment age, hot-water wait times, and fixture layout. Then, we can use this information to help you decide whether to replace your traditional water heater, perform repairs, or invest in a tankless option.

Heating and Cooling System Troubleshooting: Common Problems and Fixes

When a hot summer afternoon arrives or a sudden cold snap leaves you shivering, you need your heating, ventilation, and air conditioning (HVAC) system to be functioning at its best. In the Denver and Littleton area, maintenance and repairs are especially important because of our dry air, temperature swings during shoulder season, and dust. Older south-metro homes often contain aging HVAC systems, making timely HVAC repairs essential.

Basic heating and cooling system troubleshooting can help if your home won’t stay at a comfortable temperature. If basic steps don’t work, Elkhorn Heating, Air Conditioning, Plumbing & Electrical offers comprehensive HVAC evaluations, same-day repairs, and upfront pricing.

Quick Start: What To Check Before You Call

Before you schedule HVAC repairs, try the following tips first. Many airflow and performance problems are due to simple issues you can fix on your own. However, if the following steps don’t solve the problem, you’ll need to call for professional repairs.

  • Thermostat Settings: Verify that the thermostat mode, set point, and schedule are set appropriately. If your thermostat uses batteries, try replacing them.
  • Filters and Returns: Change out dirty air filters. Then, make sure the return isn’t blocked.
  • Breakers: If there is a tripped breaker or service switch, reset it once. Don’t keep resetting a repeatedly tripped breaker because this indicates an underlying electrical issue that needs to be fixed.
  • Vents: Open the vents. Remove any furniture, clothing, or other items that may be blocking them.
  • Clearance Around the Outdoor Unit: To maintain proper airflow, clear a 2- to 3-foot space around the outdoor unit.
  • Symptoms: Note any unusual smells, noises, ice buildup, water accumulation, short cycling, or weak airflow. These symptoms can help you determine the cause of the problem.

For your safety and the safety of your HVAC system, you should never open panels, adjust valves, or deal with refrigerants. These tasks should only be handled by a licensed HVAC technician.

No Heating or No Cooling at All

During heating and cooling system troubleshooting, it’s important to note which symptoms occur because this can help you figure out the problem. For example, a lack of heating or cooling is often due to a thermostat signaling issue, tripped breaker, or clogged filter. It can also occur if you have a failed ignition, control problem, faulty blower, activated shutoff switch, or an issue with the outdoor unit.

You don’t need to open up equipment to find out if your indoor fan, outdoor unit, or furnace burners are functioning. If air is coming out of the vents, the indoor blower is likely operating. You can also see if the indoor unit is functioning by reducing or raising the temperature setting and seeing if the unit kicks on.

While the unit is running, go outside. If the outdoor fan is turning, the outdoor unit has power, though additional problems may still be present. For ACs and heat pumps, you should also feel cooler or hotter air coming from the vents if the outdoor unit is working. 

Meanwhile, you can check furnace burners by turning the thermostat to heat mode and setting the temperature a little higher than room temperature. Many modern furnaces include a small viewing window that allows you to see the glow of the igniter. If everything is working properly, you should also feel warm air coming from the vents.

You should call for heating repairs if your heat pump or furnace does not produce heat in cold weather. Similarly, you should immediately book an appointment if your AC or heat pump won’t cool during periods of high heat, especially if there are elderly or vulnerable family members in your home. Finally, you should get help if the HVAC system stops functioning after just a few minutes or you experience repeated lockouts.

Weak Airflow or Uneven Temperatures

You may experience weak airflow or uneven temperatures if you have a dirty air filter, blocked return, dirty blower wheel, closed vents, or a duct issue. For cooling systems, a frozen evaporator coil or low airflow can cause these issues. Additionally, many air handler, control board, blower motor, and capacitor issues can lead to these symptoms.

If the temperature and airflow vary in different rooms, there may be an imbalance because of your duct layout. For example, multi-zone systems can struggle if they aren’t set up properly or when temperature demands in different rooms vary drastically. Similarly, new additions and finished basements can lead to weak airflow if the HVAC system wasn’t updated after the change.

As part of your heat pump, AC, and furnace troubleshooting, check the air filter. Verify that returns and vents are open. If these steps don’t work, you should note any airflow changes and relay them to our HVAC team when you call for repairs.

AC Problems: Warm Air, Ice, Water, and Outdoor Unit Issues

Your AC installation can encounter a range of different problems. By noting the symptom, you can determine what could be causing it.

  • Warm Air: This often indicates an airflow restriction, incorrect thermostat settings, refrigerant issues, compressor problems, or something wrong with the outdoor unit.
  • Ice Buildup: Ice can develop if there is poor airflow, dirty coils, blower issues, or low refrigerant charge.
  • Water Accumulation: If the condensate drain or condensate pump malfunctions or develops clogs, water can accumulate around the unit. Similarly, an overflowing drain pan or melting ice from a frozen coil can cause the same symptom.
  • Outdoor Unit Issues: If you notice humming, a fan not spinning, short cycling, or loud noises, the outdoor unit may require a professional inspection.

Heating Problems: Furnace and Heat Pump Symptoms

For furnace and heat pump troubleshooting, homeowners should note which symptoms occur and when. A furnace may struggle to ignite, start, then stop, cycle frequently, or blow cold air. Meanwhile, a faulty heat pump may switch to backup heat when it shouldn’t, struggle during cold snaps, or fail to heat your home completely.

These problems often stem from incorrect thermostat settings, dirty filters, blower issues, problems with the flame sensor, or control problems. You can try troubleshooting on your own by checking the thermostat settings and changing the filter.

It’s also important to note that heat pumps may occasionally blow cold air when they are using the defrost setting. This setting allows the heat pump to reverse direction during cold weather to defrost the outdoor coil. Besides cooler air coming from your vents, you may notice a little steam as ice defrosts around the outdoor unit. As long as there isn’t unusual ice buildup or extended drops in performance, the defrost mode isn’t a problem.

If our basic HVAC troubleshooting guide doesn’t help, you should schedule furnace and heat pump repairs. You should also reach out immediately if you notice burning odors or electrical problems. If a carbon monoxide (CO) alarm goes off or you smell gas, immediately evacuate the area and call for help.

Short Cycling, Constant Running, and High Utility Bills

Some HVAC problems and fixes can be handled on your own, but it depends on the cause. For example, short cycling is the term for the unit turning on and off more frequently than it should. If this occurs due to dirty air filters, you can replace the filter on your own. However, you’ll need professional help if short cycling is due to oversized or aging equipment, a frozen coil, incorrect thermostat placement, or control issues.

Other than short cycling, you may also deal with high electricity bills or constant runtimes. Nonstop runtimes can occur because of extreme weather, dirty coils, poor insulation, low refrigerant, or incorrect system sizing. If the unit is struggling to keep up in the winter, you’ll likely notice the heat pump’s backup heat kicking on more frequently.

Meanwhile, a sudden jump in your electricity bill can occur if poor maintenance or a lack of maintenance has resulted in lower energy efficiency. Aging equipment, incorrect thermostat settings, and airflow restrictions can cause higher energy bills as well.

In Colorado, our temperature swings during the shoulder seasons can put significant strain on borderline systems. If you experience recurring operation issues, it’s time to seek an accurate diagnosis.

Strange Noises, Smells, or Moisture

Unusual smells, weird sounds, and moisture accumulation are all indications that your home HVAC is not working properly. You should reach out for help if you notice any rattling, buzzing, humming, squealing, banging, clicking, or metal-on-metal sounds. 

Musty, burning, electrical, or gas odors are all signs of a problem. Additionally, you should schedule repairs if your system smells dusty when it starts up. 

If you notice moisture or water puddling, you may be dealing with a faulty condensate drain or pump. Frozen coils, humidifier leaks, or plumbing problems can also cause water accumulation.

We recommend immediately calling for repairs if you experience repeatedly tripped breakers, gas odors, or burning smells. Similarly, your carbon monoxide alarms going off or water actively overflowing in your home are signs you should reach out for help.

Homeowner-Safe Troubleshooting Checklist

As a homeowner, you can safely handle the following heating and cooling system troubleshooting on your own.

Check 1: Set the Thermostat

First, adjust the thermostat so that it is set to the correct mode and temperature.

Check 2: Replace the Air Filter

Air filters should be replaced every 30 to 90 days, depending on the manufacturer and usage. During the middle of summer or winter, you’ll likely need to replace it more frequently.

Check 3: Confirm Vents and Returns Are Open

Besides opening your vents, you should remove any furniture or clothes that could be blocking them.

Check 4: Check the Breaker

You can reset a tripped breaker once. For repeated trips, schedule professional repairs.

Check 5: Clear Debris

Remove any debris that is within 2 to 3 feet of the outdoor unit to ensure proper airflow.

Check 6: Record Error Codes and Symptoms

Note any error codes, smells, sounds, ice, or water that occur. Also, pay attention to when each symptom occurs because this can help the HVAC technician diagnose the problem.

When Troubleshooting Should Stop

If the previous tips for Denver HVAC troubleshooting don’t help, it’s time for professional help. The following signs mean you need to stop trying to troubleshoot the problem on your own.

  • You have no heat during freezing weather.
  • Your home has no cooling during periods of high heat.
  • The breaker keeps tripping.
  • You notice a burning odor.
  • There is visible ice on your unit.
  • Water is actively overflowing inside your home, or the safety shutoff keeps activating.
  • Your home’s CO alarm keeps going off, there is a gas smell, or you suspect a combustion issue.
  • Your outdoor unit produces a humming sound or consistent clicking. 
  • The fan in your outdoor unit won’t run.
  • Your system is older and keeps experiencing the same repair pattern.

At Elkhorn, we offer 100% no-interest financing, no hidden fees, and same-day services, so you can get immediate support when a problem occurs. Plus, our membership plan includes two complimentary tune-ups and special promotions. 

Repair, Maintenance, or Replacement Decision Logic

When an isolated component fails and your system is fairly new, performing repairs makes the most sense. Basic problems, like filter, airflow, coil, or drain issues, can be fixed through routine maintenance. 

In comparison, a furnace, AC, or heat pump replacement makes more sense when your system is old, the failures keep recurring, or a major component fails. Often, poor comfort and higher energy bills are early signs that your system is approaching the end of its lifespan. If a replacement is needed, 100% no-interest HVAC financing can help it fit into your budget.

FAQs

What should I check first when my HVAC system is not working? 

When you encounter common heating and cooling problems, you can troubleshoot by checking the thermostat settings, changing the filter, and seeing if the breaker has tripped. Make sure vents and returns are open and unobstructed. You should also note whether the outdoor unit and indoor fan respond when the temperature settings are changed. If there is any safety concern, immediately stop and schedule repairs.

Why do both my heating and cooling have problems? 

If your heating and cooling have problems, it may be due to the same root cause. For example, you may have damaged ductwork affecting the airflow or a faulty thermostat signal. However, it’s also possible that both systems have different problems.

When should I stop troubleshooting? 

You should immediately stop troubleshooting, shut the system off, and call for repairs if you notice gas odors, repeatedly tripped breakers, burning smells, water accumulation, ice buildup, or a lack of heating and cooling during unsafe weather conditions.

Can maintenance prevent heating and cooling problems? 

Routine maintenance can prevent many Littleton heating and cooling repairs. Through timely maintenance, we can catch dirty coils, clogged filters, weak components, drainage issues, and airflow malfunctions before peak Denver weather exposes them.

Pressure Transducer Troubleshooting: Common Faults and Fixes

While many pressure transducer issues are caused by improper installation, a pressure transducer fault can also occur from genuinely high or low pressure. If the transducer does fail, your system will become unable to accurately read refrigerant pressure. Because of the safety issues involved, it’s important to immediately reach out to Elkhorn Heating, Air Conditioning, Plumbing & Electrical for pressure transducer troubleshooting as soon as you notice any symptoms of a problem.

Quick Answer: What a Pressure Transducer Fault Usually Means

A pressure transducer is able to measure the pressure of a gas or liquid and convert it into an electrical signal. In your heating, ventilation, and air conditioning (HVAC) system, the pressure transducer is necessary for converting pressure into an electrical signal that the control board can interpret.

If you notice HVAC pressure transducer faults, it may be because the sensor has failed. This can also occur if the wiring or control board can’t read the signal. Alternatively, the pressure levels may be outside the expected range.

Pressure and voltage testing should not be handled by yourself. Because of the safety issues involved, all testing and diagnostics should be handled by a professional.

What Pressure Transducers Do in HVAC Systems

In modern AC and heat pump installations, airflow and refrigerant pressure must be precisely maintained for the safety and efficiency of the HVAC equipment. As a homeowner, you may hear about AC and heat pump pressure transducer errors during a diagnostic appointment or on a service invoice. You may also see this term mentioned through fault codes, thermostat screens, or inverter systems.

Pressure transducers are distinctly different from basic pressure switches. The biggest difference between an HVAC pressure switch vs. transducer is in how they work. A switch just opens or closes when a set threshold is reached. Meanwhile, a transducer sends a variable signal based on changing pressure levels. 

Pressure transducers are commonly used to monitor refrigerant pressure in modern heat pumps and air conditioners. Depending on the design, they may also be used for airflow-related controls or duct static pressure.

Common Symptoms of a Pressure Transducer Problem

By understanding bad pressure transducer symptoms and related problems, you can figure out if professional repairs are necessary. When something is wrong with your pressure transducer, you’ll likely notice the following problems. However, it’s also important to note that many of these signs can overlap with the symptoms of dirty coils, low refrigerant, control board issues, wiring faults, and restricted airflow.

  • After the system locks out, it displays a pressure sensor, low-pressure, or high-pressure code.
  • Your AC or heat pump starts up, but it shuts down right away.
  • The system short cycles during periods of extreme heat or cold.
  • Your variable-speed equipment doesn’t ramp up properly.
  • The outdoor unit runs erratically.
  • Your cooling and heating performance is inconsistent.
  • The thermostat or control board shows repeated sensor communication errors.

Common Pressure Transducer Faults and Causes

For better pressure transducer troubleshooting, it helps to understand the most common pressure transducer faults and why they happen.

Failed Sensor

The sensor can fail due to faulty internal electronics or diaphragm wear. Age-related drift can also cause incorrect readings.

Wiring or Connector Problems

If you have loose plugs, corrosion, rodent damage, or damaged insulation, it can end up interrupting the signal. The only way to resolve this issue is by finding and repairing the wiring or connector issue.

Control Board Interpretation Issue

When the control board doesn’t receive, process, or respond to signals correctly, it can lead to a transducer fault.

Actual High Pressure

Faults can also occur when the pressure level is genuinely high or low. High pressure can occur when there is a faulty fan motor, dirty outdoor coil, overcharge, or blocked airflow.

Actual Low Pressure

Similarly, low pressure can cause a pressure sensor fault in an HVAC system. The pressure level may fall because of undercharge, refrigerant leaks, severe airflow restrictions, and metering issues.

Contaminated or Blocked Sensing Port

Over time, the sensing port can become blocked by moisture, debris, and oil. It can also be blocked if it is installed incorrectly. When this happens, it can lead to inaccurate pressure readings.

Environmental Wear

In the Denver and Littleton area, heat pumps, high-efficiency systems, and variable-speed HVAC equipment need sensors for feedback. Unfortunately, Colorado’s dust, hail, vibration, heat, and freeze-thaw cycles can place an added strain on outdoor components and wiring. These added strains can reveal sensor, refrigerant, and airflow issues, leading to more frequent repairs and maintenance.

What Homeowners Can Safely Check First 

Before you reach out for heat pump, AC, and furnace maintenance and repairs, there are a few pressure transducer troubleshooting steps you can perform on your own.

Check 1: Write Down the Exact Fault Code or Thermostat Message

This makes it easier to remember later on, so you can look it up or relay it to one of our Comfort Specialists.

Check 2: Confirm Whether the Issue Appears in Cooling, Heating, or Both Modes

You should also see if the issue recurs in heating and cooling modes. This can help you narrow down the potential cause and is important information to relay to the HVAC technician when they arrive.

Check 3: Replace a Dirty Air Filter if Airflow Is Weak

A dirty filter can limit airflow and lower the unit’s efficiency. Ideally, filters should be replaced every 30 to 90 days at a minimum. During periods of peak use, they should be changed more frequently.

Check 4: Clear Leaves, Cottonwood, or Obvious Debris Around the Outdoor Unit

After a few windy days, debris can end up clogging your outdoor unit and preventing proper airflow. We recommend keeping a 2- to 3-foot clearance around the outdoor unit.

Check 5: Check That Supply Vents and Returns Are Open and Unblocked

Go from room to room to make sure each vent is open. Additionally, move any furniture or curtains that could be obstructing the vents or returns.

Check 6: Note Recent Symptoms: Short Cycling, Ice, Loud Fan Operation, Breaker Trips, or Poor Comfort

When you reach out for Denver HVAC pressure sensor repair, it helps our Comfort Specialists to know what symptoms you are experiencing. Each symptom indicates a different type of problem.

For the safety of your home, family, and HVAC system, you should never open panels, probe wires, or add refrigerant on your own. If the system repeatedly locks out, do not keep resetting it. Instead, call our team for a full inspection and repairs.

Our Professional Diagnostic Process

When you call us for heat pump AC and pressure sensor troubleshooting, there are a few diagnostic tools we can use to detect and diagnose the problem.

  • First, our team will verify the fault mode that appears. We’ll also check what operating mode was being used when the code occurred.
  • Our Comfort Specialist will take pressure measurements so that we can compare the sensor readings to the actual measurements.
  • We will carefully inspect your wiring, connectors, and control-board response for any issues.
  • Our certified technicians will check your refrigerant levels and pressure with the proper tools.
  • Then, we will evaluate your airflow, fan operation, and metering-device behavior. We will check the coils to see if they are dirty or suffering from ice buildup.
  • Finally, our Comfort Specialist will determine whether the transducer has failed or is accurately reporting another system problem.

At Elkhorn, we offer upfront pricing and 100% no-interest financing to make getting repairs as easy as possible. Before we begin, we will carefully explain all of the repair work needed. 

Once the repairs are done, we recommend using our membership plan for complimentary HVAC tune-ups. Through routine maintenance, you can prevent future HVAC issues and detect existing problems before they escalate.

Fixes: Sensor Replacement vs. Larger HVAC Repair

How we fix the problem is going to depend largely on what the cause is. The following are just a few of the different repairs that may be necessary in this type of situation.

  • Sensor Replacement: If the transducer reading is inaccurate or the signal is unstable, a sensor replacement may be the best option.
  • Wiring, Connector, or Control-Board Repairs: After our diagnostics are complete, we can determine if the connector, wiring, or control board needs to be repaired or replaced.
  • Coil Cleaning: Our Comfort Specialists can clean your evaporator and condenser coils so that they are better at transferring heat.
  • Fan Repair: Sometimes, airflow and temperature-control issues can be resolved by replacing the fan motor, capacitor, motor bearings, or other components.
  • Airflow Correction: If the pressure is too high because of a dirty condenser coil, condenser fan failure, or blocked condenser airflow, your system may need to have its airflow corrected.
  • Refrigerant Repairs: When a refrigerant leak is detected, our team will quickly locate and fix the leak. Afterward, we can recharge your system.

When repairs are relatively minor and inexpensive, it often makes sense to just perform the repairs. This equation changes if you’re dealing with an older unit that requires frequent repairs or a major component repair. Once the HVAC system is close to the end of its normal lifespan, you’ll likely notice rising energy bills, declining indoor comfort, and more frequent repairs. Eventually, it may be more cost-effective to install a new AC or furnace than pay for another repair.

FAQs

Does a pressure transducer fault mean the sensor is bad?

Not necessarily. While a fault may occur because of a malfunctioning sensor, it can also occur because there is a real pressure change. For example, many airflow, refrigerant, coil, control, and fan problems can lead to detectable pressure changes. Commonly, pressure transducer faults occur because of loose wiring, damaged wiring, or an unstable power supply.

What is the difference between a pressure switch and a pressure transducer? 

A pressure switch is designed to open and close at a set point. In comparison, pressure transducers are set up to convert changes in pressure into electrical signals, so your control board has detailed pressure information.

Can I test a pressure transducer myself? 

No, this isn’t a DIY task. It involves refrigerant pressure, control-board diagnosis, and electrical signals. Because of the safety risks involved, homeowners should never test a pressure transducer on their own.

Can a heat pump have a pressure transducer fault? 

Yes, it can. Modern heat pumps may be designed with a pressure transducer so that they can get pressure feedback during heating and cooling modes. If the transducer fails or the pressure level is off, there may be a pressure transducer fault. Because multiple issues can cause the transducer fault, it’s important to book a diagnostic appointment to determine the cause.

Air Handler Troubleshooting: Fan, Control Board, and Airflow Issues

When your air handler refuses to switch on during a hot summer day in Denver, it can cause a significant amount of stress. To beat the heat, you can use our air handler troubleshooting guide to remedy minor issues. For major repairs, electrical work, and anything involving refrigerant, you’ll need to reach out to Elkhorn Heating, Air Conditioning, Plumbing & Electrical for professional repairs.

What an Air Handler Does and Why Symptoms Can Be Confusing

An air handler is an indoor unit or assembly that’s responsible for moving conditioned air throughout your home. The blower motor, evaporator coil, and controls are housed inside the air handler cabinet. When the thermostat signals the air handler’s control board, your blower motor and other components start working. Then, the blower motor powers the blower fan to push air into your home. 

During this process, airflow is pushed over the evaporator coil, which is a network of refrigerant tubing and fins that absorbs heat from the air. The refrigerant absorbs heat from the air. Water condenses around the coil like it does around a glass of ice water. As the water drips, it is collected in a drain pan and drained outside your home through a condensate drain line.

If any of these components stop functioning, your air handler will stop working. Because the air handler sits at the nexus of your system, an air handler issue can also appear like an AC, furnace, heat pump, thermostat, or ductwork problem.

In Denver and Littleton, there are additional factors that can affect your air handler’s functionality. Many homeowners have heating, ventilation, and air conditioning (HVAC) equipment in their closets, basements, attics, and utility rooms. Because HVAC equipment is often hidden away, it can make it harder to inspect and notice issues in a timely way.

Our local HVAC systems must also deal with dust, wildfire smoke residue, and cottonwood. Thanks to our rapid heating-to-cooling season transition, there’s also an added strain on filters, coils, and airflow.

Quick Symptom Map for Homeowners

To determine the type of air handler problem you’re dealing with, it helps to first consider the symptoms.

  • No Air From the Vents: Often, this type of symptom occurs if the blower motor isn’t pushing any air through the system. Similarly, an issue with the control board, safety switch, power supply, or thermostat signal can also prevent the air handler from turning on and running properly.
  • Poor Airflow: Dirty filters, ductwork restrictions, clogged coils, blower speed issues, and an aging motor can all result in airflow problems.
  • Fans Run Constantly: If your fans seem to run all the time, your relay may be stuck, or there could be a control board issue. Wiring problems and fan settings can also cause this to occur.
  • Outdoor Unit Runs, but Fan Won’t Start: When this symptom happens, you may have an issue with the control board, indoor blower, capacitor (if equipped), relay, or motor.
  • AC Air Feels Warm: An air conditioner may struggle to cool the air if there’s a problem with your outdoor unit, such as if the compressor is broken or the unit’s breaker has tripped. Frozen evaporator coils, low refrigerant levels, and airflow restrictions can also cause air to feel warm when it comes out of vents.
  • Water Near the Indoor Unit: Water near your indoor unit can often occur if your condensate AC pump fails, your condensate drain line is clogged, or the float switch isn’t working. Frozen coils can also cause pooling water if the melting ice overwhelms the unit’s drainage system.

Blower Fan and Motor Problems

Normally, your blower fan is responsible for moving air across the evaporator coil and through your ductwork. When your blower motor is not running, it may cause slow or no airflow. You may also notice burning odors, vibrations, humming sounds, intermittent starts, and buzzing noises. Often, the fan will shut down after just a few minutes.

Blower motors can struggle if there is overheating, capacitor malfunctions, or wiring issues. Additionally, worn motors, dirty blower wheels, and bad belts on older systems can also be an issue.

As a homeowner, you can easily check the air filter and fan settings. Then, remove any blockages or obstructions in front of the vents and returns. You should also note any unusual behaviors so that you can share them when a comfort specialist arrives for your diagnostic appointment.

If basic troubleshooting doesn’t help, you can reach out to us for your Denver air handler repairs. Our team will test the motor and capacitor. Then, we’ll check the amperage and look for other blower compartment issues. Once we’ve diagnosed the problem, we can recommend the best AC or heat pump repairs for your home.

Control Board, Relay, and Transformer Issues

The control board is like the brain of your HVAC system and is responsible for coordinating system operations. When your control board, relay, or transformer is at fault, your blower motor might not run, or the system may start and then stop. Error lights, a fan running constantly, and intermittent operation are also signs of this issue.

Transformers and relays also support electrical components that can lead to an air handler fan not working and unusual control behavior. As a homeowner, these aren’t components that are safe for you to deal with. While you can note error codes, unusual sounds, and performance changes, you shouldn’t remove the covers or probe wiring. Instead, call Elkhorn to schedule your AC, heat pump, or furnace repairs.

Airflow Restrictions and Indoor Comfort Clues

Littleton HVAC airflow problems can be the source of your performance issues. For example, a clogged air filter, blocked return grille, or closed supply vents can restrict the amount of air that makes it to each room. 

While you can address a dirty air filter or a closed vent on your own, other airflow restriction issues would need to be handled by a professional. Clogged blower wheels, dirty evaporator coils, incorrect blower speeds, failing motors, and damaged ductwork must be addressed by an experienced HVAC technician.

In the Denver and Littleton area, we face unique challenges. Dust-heavy homes, renovation debris, pets, and wildfire smoke seasons can quickly clog air filters. Additionally, home additions, room changes, and finished basements can change your home’s airflow needs.

Frozen Coil, Drainage, and Safety Switch Overlap

An air handler’s frozen coil can also result in performance problems. If there are airflow restrictions, it can cause your evaporator coil to freeze. When this occurs, you may notice weak airflow, poor cooling performance, and short cycling. If your system uses an AC pump, the melting ice from the coil can end up triggering a float switch shutdown if it overwhelms the pump’s reservoir.

If there is visible ice on the coils, the water is backing up, or your system keeps shutting down, turn off the unit. Then, call for professional diagnostics and repairs.

Homeowner-Safe Troubleshooting Checklist

As a homeowner, there are a few safe steps you can perform on your own.

Check 1: Confirm the Thermostat Settings

First, make sure the thermostat has the right mode, set point, and fan setting.

Check 2: Replace the Filter

Check the filter to see if it is dirty or overdue for a replacement.

Check 3: Open Returns and Supply Vents

Go through your home to verify that all of your returns and supply vents are open and unblocked.

Check 4: Look for Unusual Symptoms

From a safe location, note any indications of ice, unusual smells, water, or error lights.

Check 5: Listen for Unusual Sounds

Pay attention to any unusual buzzing, clicking, vibration, or humming noises. Also, listen for repeated start attempts.

Check 6: Note When It Happens

While your unit is running, pay attention to which mode and situations it occurs in.

For the safety of your home and HVAC system, you should never bypass switches, open electrical panels, or test capacitors on your own. Additionally, don’t continue running a system if it has a burning odor or ice buildup.

When To Call for Same-Day Services

If basic troubleshooting doesn’t help, our team is just a phone call away. We recommend calling for same-day services if you experience any of the following situations.

  • The weather is especially hot or cold, and your AC isn’t producing any airflow.
  • You noticed a burning smell, indicating a potential electrical hazard.
  • The evaporator coil keeps freezing.
  • Your breaker keeps tripping.
  • Your outdoor unit is running, but the indoor blower isn’t moving any air.
  • The fan runs constantly.

Repair vs. Replacement: Which Option Is Right for Your Home?

After air handler troubleshooting, the actual repair is often relatively fast. If the fix involves replacing or repairing the capacitor, relay, filter, motor, drain, thermostat, or control board, performing the repair is likely the best course of action. Similarly, blower cleaning is straightforward and relatively inexpensive.

While repairs and maintenance are the best choice in some circumstances, this isn’t always the case. An AC replacement or new furnace installation may be necessary if the unit is already getting older and requires frequent repairs. If you do need to replace the unit or perform major repairs, our 100% no-interest financing can help with budgeting.

Remember Your Maintenance and Prevention

Preventive maintenance is one of the most important things you can do to avoid future issues. As a homeowner, you should change the air filter every 30 to 90 days and schedule routine maintenance. Elkhorn makes routine maintenance easy through our Whole Home Comfort Plan and complimentary tune-ups.

During the tune-up, our comfort specialists will clean the blower and inspect your drain line for clogs. Then, we can inspect and clean the coils. We will check your thermostat, balance your airflow, and run performance tests to make sure that everything is in working order.

Frequently Asked Questions

Why is my air handler not blowing air? 

If your air handler isn’t blowing air, it could be due to a few common symptoms. For example, a failed blower motor will keep air from getting distributed into your home. Issues with the relay or transformer, control board malfunctions, a frozen evaporator coil, problems with the thermostat’s signaling, tripped safety switches, and dirty air filters can also keep the air handler from blowing air.

How do I know if the air handler control board is bad?

Common air handler control board symptoms will indicate if the board itself is the problem. For example, a fan running constantly and intermittent starts can happen if the control board is faulty. Any time the system doesn’t respond to thermostat calls, there are flashing error codes, or the blower motor’s behavior doesn’t match your thermostat settings, you may have a control board malfunction.

What causes weak airflow from vents?

Two of the most common and preventable reasons for weak airflow from vents are clogged filters and obstructed or closed vents. If replacing the filter and opening vents doesn’t improve the airflow, you may be dealing with a dirty coil, ductwork restrictions, blower motor malfunctions, or a dirty blower wheel. All of these problems should be addressed by a professional HVAC technician.

What air handler checks should homeowners not try?

While many routine maintenance tasks can be safely performed by homeowners, you should never handle any refrigerant or electrical components yourself. Additionally, leave control board diagnoses, motor testing, and capacitor testing to the experts.

AC Pump Not Working? Causes and Fixes

When an AC pump is not working, your entire AC system can turn off. Because this problem can be due to different sources, you have to find the root cause before you can fix it. With the help of Elkhorn Heating, Air Conditioning, Plumbing & Electrical, Denver and Littleton homeowners can get same-day services for unexpected AC issues.

Quick Answer: Why an AC Pump Stops Working 

When most homeowners refer to the AC pump, they are talking about the condensate pump. This device is responsible for transferring water from the indoor AC coil or drain pan to a safe location. 

If the pump stops working, it is often because of a lack of power, a clogged drain line, algae or debris, loose tubing, a faulty pump motor, a stuck float switch, or an overflowing drain pan. While there are a few troubleshooting tips you can do on your own, you should seek professional repairs anytime tripped breakers, standing water, or repeated shutdowns are involved.

What the AC Condensate Pump Does

The AC condensate pump plays an important role in your heating, ventilation, and air conditioning (HVAC) system. As a part of your AC or heat pump’s normal processes, excess humidity is removed from warm air as it passes over the indoor coil. 

After this humidity condenses around the coil, the moisture drips onto a drain pan beneath the coil. From there, the water normally flows out of the home through the drain line with the help of gravity. 

In Denver and Littleton homes, gravity-based drainage isn’t always possible. Some homes have basements, utility closets, finished lower levels, or high-efficiency equipment that are positioned in a way where gravity-based drainage isn’t possible. In these instances, the water goes to a reservoir that holds the water until the condensate pump can pump it out through the discharge tube.

Within this system, there is also a float switch that is connected to a lever. When the water level rises, the float switch moves the lever and triggers the pump to turn on. If there is no water in the reservoir, the float switch sinks and the lever shuts off the pump.

Condensate pumps aren’t just for cooling systems. Many Colorado homes have high-efficiency furnaces or heat pumps that also create condensate, so this device can be used for multiple purposes.

Signs Your AC Pump May Not Be Working

In our Colorado summer cooling cycles and shoulder-season humidity, AC pumps have to work overtime. If your AC pump is not working, there are a few signs that you may notice.

  • There is a musty odor coming from the tubing or drain components.
  • You can see visible mold, debris, or algae buildup.
  • The pump makes a humming, clicking, or buzzing noise.
  • There is standing water near your indoor unit, air handler, or furnace.
  • Your pump runs constantly.
  • There is water in or around the drain pan.
  • You noticed water stains on the ceiling, wall, or floor near the equipment.
  • The pump reservoir fills up, but it doesn’t empty.
  • Your AC starts and shuts off quickly because the float switch triggers it to turn off.

Because these symptoms could be due to a frozen coil, clogged drain line, or other issue, it’s essential to reach out for a professional furnace, AC, or heat pump inspection.

Homeowner-Safe Checks Before Scheduling Service

If you’re dealing with a Denver or Littleton AC drainage problem, there are a few safe checks you can make before you reach out to our team for professional repairs.

Check 1: Turn Off Your System

If the water is overflowing or you notice water near any electrical components, you should immediately turn your system off to prevent electrical hazards and water damage.

Check 2: Confirm the Thermostat Settings

If water is backing up or overflowing, verify that the thermostat is turned off so the system does not continue operating. For the safety of your home and HVAC system, you don’t want the thermostat to keep switching on the AC while you have water backing up.

Check 3: Look for Drainage Issues

Visually inspect the drainage line for disconnected tubing and obvious kinks without opening any equipment panels. Then, see if the pump reservoir is full.

Check 4: Check the Pump’s Outlet

Some pumps are hardwired into the HVAC unit’s electrical system. For pumps that use a separate outlet, you can verify that the pump is plugged in. However, you should never handle wet plugs or exposed wiring.

Check 5: Note the Position of the Float Switch

Look at the float switch to see if it is in the high position. If it has shut the AC off, don’t bypass it. Instead, call our comfort specialists for professional HVAC repairs.

Check 6: Replace a Dirty Air Filter

If your air filter is clogged, it can reduce airflow into your HVAC system. This can lead to a frozen evaporator coil. As the coil thaws, it can produce more moisture than normal, leading to a full reservoir and drainage issues. By replacing your air filter, you can prevent the evaporator coil from freezing.

For the safety of your home and family, you should never open electrical compartments or bypass safety switches. Never repeatedly reset breakers because frequent tripping indicates an underlying electrical problem. Additionally, you should never pour harsh chemicals into your condensate drain lines because they can melt PVC pipes and corrode metal parts.

Common Causes of Condensate Pump Failure

By understanding the following condensate pump causes and fixes, you can figure out what’s going on with your HVAC system. From an AC drain pan overflow to tripped breakers, each underlying problem causes different symptoms.

  • No Power to the Pump: If there’s no power to your HVAC system, it may be due to a tripped breaker, a failed outlet, or an unplugged pump. It can also occur if you have a wiring or switch issue.
  • Stuck or Failed Float Switch: The switch is normally responsible for avoiding an overflowing reservoir. If the switch becomes stuck, the unit may not turn on at all as a failsafe. It may also have other unusual cycling behaviors.
  • Clogged Drain Line or Discharge Tubing: This type of problem often develops if there are minerals, dust, insulation debris, algae, sludge, or other materials blocking the drain line or discharge tubing.
  • Failed Pump Motor: Once the pump motor starts to fail, the pump will struggle to remove water from the reservoir as it fills up.
  • Loose, Cracked, or Disconnected Tubing: Sometimes, tubing can become loose or disconnected. Because this allows water to leak out, you may notice pooling water around the unit.
  • Dirty or Frozen Evaporator Coil: If the evaporator coil is dirty, it can’t transfer heat properly and is more likely to freeze. As the ice melts, it can overwhelm the drainage system and cause the same symptoms as a pump failure.
  • Improper Pump Sizing or Installation: When the pump is too small or installed poorly, it can lead to unreliable drainage.
  • Age and Wear: Over time, plastic reservoirs, discharge tubing, floats, and motor parts can start to wear out. When this happens, the worn component will generally need to be replaced.

Why the AC May Shut Off When the Pump Fails

The reason an AC system shuts off when condensate pump problems occur is because of the float switch. This switch is designed to stop cooling when the water rises too high. By doing so, it prevents the reservoir from overflowing and causing water damage around your HVAC equipment. You should never try to bypass this safety mechanism because it’s designed to protect your home and HVAC system from costly repairs.

If you are experiencing repeated shutoffs, water near finished surfaces, a full pump, or a hot home, don’t wait to get help. Through Elkhorn’s same-day services, you can get a fast diagnosis and repairs.

What Elkhorn Will Diagnose and Repair 

When our comfort specialists arrive at your home, we’ll quickly perform the following diagnostics.

  • Verify the electrical safety of your outlet, switch, and pump.
  • Check the drain line, discharge tubing, condensate line, and termination point for kinks, blockages, and other problems.
  • Test your system’s airflow and performance.
  • Look at the condition of the coils, and note any signs of freezing that can create extra water.
  • Inspect your float switch operation, pump cycling, and reservoir condition.

Once we’ve finished our inspection, we can determine why the AC pump is not working and whether it requires a simple repair, drain line cleaning, or pump replacement. In some cases, it may be a symptom of your general AC installation’s performance. If this is the case, we can help you plan ahead for when an AC replacement may become necessary. 

No matter what the problem is, our team will provide a clear explanation before we begin any work. Denver and Littleton residents can rely on Elkhorn for their expert guidance, upfront pricing, and no hidden fees.

When Repairs, Replacements, and Prevention Make Sense

After we evaluate your system, we can determine if repairs, replacements, or prevention makes the most sense. Denver AC condensate pump repair is generally the best choice if you’re dealing with a low-cost repair and a newer system. If the unit has had minimal repairs in the past and works well otherwise, repairs are generally the best route.

Older ACs, furnaces, and heat pumps may already be reaching the end of their expected lifespan. If the unit has a history of frequent repairs or poor performance, the best option may be to get a replacement. 

Affording a large repair or equipment replacement can be challenging. With our 100% no-interest financing, you can schedule HVAC services when it works for you. 

Through timely maintenance, you can prevent and delay future repairs. Through our maintenance membership, you can get complimentary spring and fall tune-ups. Our team can check your condensate drainage, coils, and filters to prevent this problem from happening again.

Frequently Asked Questions

Why did my AC shut off when the condensate pump stopped working? 

When water starts backing up in the drain pan or pump reservoir, it triggers a float switch. This switch is designed to shut off your AC so that water doesn’t overflow into your home and cause water damage. If your unit is off because your AC condensate pump is not working, leave it off and call for repairs. 

Does water near my AC always mean the pump failed? 

If you notice water near your AC, it doesn’t necessarily mean that your pump has failed. This can also occur due to a clogged drain line, frozen evaporator coil, kinked tubing, or a power problem. Because of this, it’s important to have one of our comfort specialists come out to test the pump and drainage path so that we can recommend the right repairs for your situation.

What should I do first if my AC pump is not draining? 

If your air conditioner pump is not draining and water is overflowing, you should shut it off. Additionally, always shut off the AC if there is a risk of water exposure near electrical components.

Then, you can troubleshoot by seeing if there is any disconnected tubing. If this doesn’t work and the pump reservoir remains full, schedule AC repairs right away.

Can maintenance prevent condensate pump problems? 

Absolutely. While pump motors can eventually die, many problems can be caught through timely maintenance. Our team will inspect for sludge buildup, coil issues, dirty filters, and drainage problems during the inspection. By finding and fixing these issues early, we can prevent unexpected breakdowns from happening during Denver and Littleton’s summer weather.
