Buy a Fan, Plant 5 Trees!

CHC is donating a portion of every whole house fan sold in support of the National Forest Foundation’s 50 Million for Our Forests campaign, the largest campaign in support of reforesting our publicly-owned National Forests.

For every whole house fan sold, CHC will fund the planting of 5 trees. Together, we'll restore thousands of acres of our National Forests.

Whole House Ventilation Fans

Whole house ventilation fans provide adequate airflow for your home to experience a complete air exchange every 3-4 minutes, creating a more efficient, comfortable and healthy home environment.


Additional attic fans and vents are often required to ensure your whole house fan system operates at peak performance. We recommend a minimum of 3 CFM (cubic feet per minute) of ventilation for every square foot above ground in your home.

Whole house ventilation fan systems reduce strain on existing home cooling systems by maintaining comfortable temperatures throughout your home while cutting your AC usage and home cooling costs by as much as 50-90%!

Attic Fan Installation

Attic fan installations are often needed to match the airflow in the attic to the airflow from your whole house fan. We recommend a minimum of 1 square foot (144 sq. in.) of net free (sfnf) attic ventilation for every 1,000 cfm of air moved by the fan. Most homes need additional attic fans or vents to complete the installation of a whole house fan by adding passive vents or a solar powered attic fan.


From solar attic fans to passive gable vents and more, we install attic fans and vents in a variety of makes and models to suit your home ventilation needs. For homes with tile or metal roofs, we will install attic fans and vents in the existing soffits or gables to minimize roof alterations.


We are Colorado's top-rated attic fan installers with the solutions you need to complete your whole house ventilation system!

Whole House Fan Reviews

How Whole House Fans Work

Using your whole house fan couldn't be easier! When the outside air temperature is cooler than inside your home or attic, do the following:

1 Open a few windows 4-6 inches

2 Turn on your whole house fan using the switch, portable remote, or timer

3 Feel a nice, cool breeze as air passes through your home, replacing all the stale, trapped air 

4 Experience a complete air exchange in your home in just 3-4 minutes

5 Save money as warm air is expelled from your attic, keeping your home comfortable for hours and cutting cooling-related energy use by up to 90%
