Air conditioner installation cost factors:

The AC system's size

AC size is determined by home size, home layout, and other factors. Larger AC units will come with higher price tags. But if the system is sized right, that unit will lower their energy bills and give them cooling comfort across their entire home.

The system's efficiency levels

The more efficient your AC, the more money you save every month on energy bills. AC efficiency is measured by its SEER rating, and while higher SEER-rated ACs have a higher outright investment cost, the savings you see every month can help you pay off that cost and then some.

Ductwork modifications

A reliable duct network is so important to ensuring cool air gets to every part of your home. Ductwork that's in disrepair can cause major air loss and cost you a fortune in energy bills. Suffice to say, getting it repaired at the same time as the installation is an investment you won't regret.

Our AC installation process

  • Schedule your free estimate

    You can schedule a free, no-obligation estimate with the Cooper Green Team by calling our office at (720) 605-7270 or reaching out to our customer service team online.

  • Get high-efficiency system options

    During the estimate, a Project Manager will perform a load calculation on your home to calculate the right AC size. Afterward, they'll share several high-efficiency AC models which we believe are the best fit for your home and budget.

  • Let us install your system

    After the AC model has been selected, it's simply a matter of sending our crew out to your home to complete the installation. Most installations take around a day to complete. Afterward, your lead installer will share information with you about the proper care and use of your new air conditioner.

  • Enjoy lifetime savings and better comfort

    With your brand-new high-efficiency AC system, you'll get immediate energy savings and improved whole-home comfort. On top of that, you'll get peace of mind from knowing your new system is protected by parts and labor warranties from Lennox and the Cooper Green Team.

"Outstanding and very professional…"

Cooper’s team was outstanding and very professional. Got here at the time promised, work was completed and the installation looks great. After they were done, you couldn’t tell they had been here. Not a footprint or spec of dust could be found. A pleasure working with this company.
