How much does a furnace replacement cost in Colorado?

Low price:$6,985

Our avg price:$8,273

High price:$12,068

Why are our prices slightly higher?

It comes down to two reasons: the quality of the systems we install, and the experience of our installers. To save our customers more money over the long run, we make it a point to source only the highest-efficiency furnaces that both last longer and lower energy bills. As far as our installers go, you simply won't find anyone better. A Cooper installation team will never let you down. For many customers, that peace of mind is worth every penny.

Furnace installation cost factors:

System size

When we talk about furnace size, what we're really talking about is power. And power is a measure of a furnace's BTU output. It is important to have the right size furnace for your home and ductwork. Oversizing a furnace can cause even more issues than an undersized furnace. Just like a water hose that has too much pressure, an oversized furnace can build up pressure causing additional strain on the system as well as short cycling creating uneven temperatures. Likewise, if the furnace is undersized, it can struggle to heat your entire home and cause longer run cycles using more energy. We'll make sure your new furnace is sized perfectly for your home during a free in-home consultation.

System efficiency

All furnaces have an AFUE rating which tells you how efficient the system is. The higher the AFUE rating, the more the furnace will cost upfront, and the more energy savings you'll see over the long run.

Comfort features & add-ons

You can add all sorts of features to furnaces these days. You can combine your installation with a new smart thermostat, or upgrade your furnace to run smarter and more efficiently with modulating burners and variable blower motors. These items can add to the installation costs, but they also add additional value and comfort. Through our experience as Colorado's top HVAC replacement company, we see the benefits of these added values every day and love to make sure our customers are educated on all options to make sure your purchase is the right fit for you.

Our furnace installation process

  • Schedule your free estimate

    You can schedule your estimate by calling us at (720) 605-7270 or by requesting an appointment online. We'll reach out quickly to set up a day and time that works for you.

  • Get high-efficiency system options

    The Project Managers at Cooper know their stuff. They'll share a variety of furnace systems with you and let you decide which is best. We'll also try to find you any available utility, state, federal, and manufacturer rebates at this time.

    In most scenarios, one to two days is the most common timeframe for installations. Although this depends on the existing system and new system requirements and modifications.
