Furnace Installation & Replacement


Elkhorn Heating, Air Conditioning, Plumbing & Electrical provides furnace installation and replacement in Aurora, CO, for homeowners ready to replace equipment that has reached the end of what repairs can reasonably extend, or to move into a system that can actually keep the full home warm through a Colorado winter.

Aurora’s housing range from older west Aurora ranches with original equipment that may be decades old to newer east Aurora planned communities where first-cycle systems are approaching the end of their efficient service life means the installation conversation has to start with what the specific home actually needs. Call 720-615-0098 to schedule an estimate and find out what the right system looks like for your home.

Aurora furnace replacements do not follow a single profile. A 1960s ranch in west Aurora may have a furnace that has been patched over the years and is now well past the point where another repair makes sense.

A newer two-story in east Aurora may have a system that is technically younger but has been underperforming for several winters. A good installation should end with a system sized for the actual home, set up to deliver heat where it needs to go, and ready to hold through the full season.

Local Furnace Installation & Replacement in Aurora, CO

Aurora’s housing diversity means duct condition and home layout vary considerably from one neighborhood to the next. An older ranch may have original ductwork that has not been assessed in decades. A newer multi-story home may have longer duct runs that require a furnace with the airflow capacity to reach the upper floor consistently. Both details matter before any equipment is selected.

Aurora winters are cold enough that the efficiency gap between older equipment and a current high-efficiency condensing furnace adds up over time. Homeowners who are replacing a furnace that was already running inefficiently are usually stepping into meaningful operating cost savings, not just better comfort.

Aurora homeowners usually look for a few practical things when replacing a furnace:

  • Local Fit: Aurora’s furnace replacements span a wide range of home types, duct conditions, and system histories. Our team works across older west Aurora ranches and newer east Aurora planned communities and factors the actual home’s layout and duct condition into the sizing and installation approach.
  • Honest Sizing: We size systems based on a proper load calculation for the full home and the duct system it has. An oversized furnace short-cycles and can produce uneven heat as reliably as an undersized one.
  • Verified HVAC Credentials: NATE-certified technicians backed by ACCA membership, Trane Comfort Specialist status, and BBB A+ accreditation.
  • Upfront Pricing: We explain the scope and cost before work begins.
  • Whole-Home Support: Elkhorn handles HVAC, plumbing, and electrical under one roof, which matters when an installation involves more than just swapping the heating equipment.
  • Maintenance Plan Support: The Whole Home Comfort Plan puts a maintenance routine in place from the first season.
  • Financing Options: Larger furnace installation projects can be financed, which makes the timing easier to work with.
  • Homeowner Feedback: Homeowners consistently mention straight talk about what the home needed, a crew that worked cleanly, and a system that held the whole house at temperature from the first time it ran.

That combination makes a larger project easier to navigate from estimate through the first winter.

When Furnace Replacement Makes Sense in Aurora

Not every struggling furnace in Aurora needs to become a replacement project right away. Here is a practical way to think through the decision.

When Repair Is Still the Right Move

If the furnace is under fifteen years old, the issue is limited to one or two parts, and the system has heated the home reliably, a focused furnace repair is often still the better path. That is especially relevant in newer east Aurora homes where equipment may still have useful service life remaining. A solid furnace repair can buy several more seasons without turning a manageable fix into a larger project than it needs to be.

When Replacement Becomes Worth Considering

A furnace that is fifteen to twenty years old, has stacking repairs, a heat exchanger with a confirmed crack, or equipment that can no longer hold the home at thermostat temperature through a Colorado winter is usually a reasonable replacement candidate. In older west Aurora homes, it is also worth considering whether the duct system can support a current system properly. Sometimes duct condition is part of the problem, not just the furnace. We will put the full picture in front of you so the decision makes sense before you commit.

Furnace System Options for Aurora Homes

The right system depends on the home’s size, duct condition, how many levels need heating, and efficiency goals.

  • Standard Gas Furnace (80% AFUE): A cost-effective starting point for homes where duct condition is good and the priority is straightforward replacement without a long payback calculation.
  • High-Efficiency Gas Furnace (90-97% AFUE): Lower operating costs over time. A practical choice in Aurora where colder winters mean more hours of furnace runtime and a meaningful efficiency gap to close between old and new equipment.
  • Two-Stage or Variable-Speed Furnace: Better heat distribution across multiple levels with quieter operation. Particularly useful in newer multi-story east Aurora homes where the upper floor has historically been harder to warm than the main level.
  • Electric Furnace: An option where gas is not available, though operating costs in Colorado are generally higher than gas over time.

What the Furnace Installation Process Looks Like

  1. We start with a load calculation and a walkthrough of the home to understand floor plan, duct condition, insulation, and any areas where heating has been inconsistent.
  2. We review furnace system options that fit the home’s actual needs and explain the efficiency, cost, and comfort trade-offs in plain language.
  3. We provide upfront pricing before any work begins so there are no surprises on the invoice.
  4. On installation day, we remove the old equipment, prepare the installation site, and install the new system to manufacturer specs and local code requirements.
  5. We test the system, walk you through operation and thermostat settings, and confirm everything is running correctly before we leave.

A good installation day leaves the home heating the way it was supposed to, with a homeowner who understands exactly what was installed and why.

Protect Your New System With Our Whole Home Comfort Plan

A new furnace is a meaningful investment. Regular furnace maintenance keeps it performing at the level it was designed for. The Whole Home Comfort Plan puts a maintenance routine in place from the first season so wear is caught earlier and the system holds its efficiency longer.

Plan benefits that matter on the heating side include:

  • Fall Furnace Precision Maintenance: Annual service that gets the system ready before the cold weather arrives, with attention to the specific pressures Aurora homes face across a wide range of home ages and duct conditions.
  • Priority Scheduling: Getting onto the schedule tends to go faster for plan members.
  • Repair Discounts: Follow-up work is easier to manage when the plan is already in place.

The Whole Home Comfort Plan is worth asking about when you schedule your estimate. Starting maintenance from the first season protects the investment you just made.

FAQs About Furnace Installation & Replacement in Aurora, CO

How do I know when it is time to replace my furnace instead of repair it?

Age, repair history, heat exchanger condition, and how well the system still heats the home are the main factors. A furnace over fifteen years old with stacking repairs or a cracked heat exchanger is usually worth replacing. We will look at the whole situation and give you a recommendation based on your home’s actual condition.

What AFUE rating should I look for in a new furnace?

For Aurora winters, a high-efficiency condensing furnace in the 96-97% AFUE range typically makes sense because the furnace runs more hours per season and the efficiency savings add up over time. We can help you work through the comparison before you decide.

What size furnace does my Aurora home need?

Sizing depends on square footage, ceiling height, insulation, window placement, duct layout, and the number of levels being heated. Homes with significant duct runs or older ductwork may need a different sizing approach than what square footage alone suggests. We use a proper load calculation every time.

How long does a furnace installation take?

Most standard furnace replacements take one day. Installations involving duct modifications or venting changes may take longer. We will give you a realistic timeline before work begins.

Do you offer financing for furnace installation?

Yes. Financing options are available for furnace installation and replacement projects. We can walk you through what is available before you commit.

What brands do you install?

We are a Trane Comfort Specialist and install Trane equipment. Every recommendation starts with what fits the home and how the duct system is set up.
