We Install All Types of Furnaces

We install the major furnace types commonly used in Denver and Littleton homes.

Gas Furnaces

Gas furnaces are one of the most common home heating systems. They are known for strong heating performance and good efficiency when properly installed and maintained. They are a practical fit for homeowners who want dependable whole-home heat and already have natural gas service available.

Electric Furnaces

Electric furnaces are a good option for homes without natural gas access or for homeowners who prefer an all-electric solution. They are simpler to install but may have different operating costs depending on electricity rates. They can also be a strong choice for households that want a straightforward heating setup with fewer fuel-related components to maintain.

High-Efficiency Furnaces

High-efficiency furnaces are designed to convert more fuel into usable heat, often with an AFUE rating of 90% or higher. These systems can reduce energy use and lower heating bills over time. For homeowners planning to stay in the home long term, they can offer stronger comfort performance and better operating value through Colorado’s colder months.

What to Consider Before Installing a New Furnace

Before choosing a furnace, it’s important to review a few key factors:

  • Home Size: Your home’s square footage affects the size and heating capacity your furnace needs.
  • Heating Needs: Some homes need more consistent heat output or better airflow, depending on layout and insulation.
  • Budget: It’s important to balance initial installation cost with long-term energy savings and reliability.
  • Furnace Type: Gas, electric, and high-efficiency options each offer different advantages depending on your home and goals.
  • Efficiency Rating: Higher-efficiency furnaces often cost more upfront but can reduce energy bills in the long run.
  • Installation Cost: Installation complexity, furnace size, and any required upgrades all affect total cost.

A professional HVAC contractor can help you compare options and select the system that fits your needs best.

  • Stronger long-term value for your home

Upgrading from an aging furnace can improve both comfort and confidence during the coldest months of the year.

Will a New Furnace Improve Energy Efficiency?

Yes. Newer furnaces are generally much more efficient than older models. Installing a new furnace can help:

  • Reduce wasted energy
  • Lower heating bills
  • Improve overall system performance
  • Decrease your long-term operating costs

A high-efficiency furnace often delivers the best savings over time.

Furnace Installation Cost in Denver & Littleton

The cost of a new furnace varies depending on factors such as:

  • Home size
  • Furnace type
  • Efficiency level
  • Installation complexity
  • Additional upgrades or modifications needed

Larger homes and high-efficiency systems typically cost more upfront, but they can also provide stronger long-term value.

The best way to understand your cost is with a professional estimate based on your specific home.

Permits and Professional Installation

In Colorado, a permit is generally required to install a new furnace. Permit requirements can vary by project and location, and a licensed HVAC contractor can help explain what applies to your installation. Our team can help handle the process and make sure your installation is completed properly.

Professional installation matters because it helps ensure:

  • Safe system operation
