Get Your Whole House Fan Installed Soon! 

We are Colorado's top-rated whole house fan installer — all whole house fans, attic fans and vents in-stock and available for install! Quiet, cool Colorado whole house fans are among the most energy efficient home cooling systems, reducing energy costs and improving air quality for a fraction of the cost of A/C!

The Best Whole House Fan Systems

The first step in creating the best whole house fan system is to choose the best whole house fan for your home! We recommend an attic fan that provides 3 CFM (cubic feet per minute) for every square foot above ground in your home. Providing adequate airflow allows your whole house fan to complete air exchanges every 3-4 minutes and create a quiet, cool, comfortable, and healthy indoor environment. The best whole house fans are an excellent AC alternative, but can also cut your AC-related energy costs by up to 90% when used in conjunction with your home cooling system!

Whole House Ventilation Fans

Attic fans and vents are a key component of every whole house ventilation fan system, and manufacturers require it as part of the whole house fan installation.

The most efficient home ventilation systems match the airflow in the attic to the airflow from the whole house fan. We recommend a minimum of 1 square foot (144 sq. in.) of net free air (sfnf) ventilation for every 1,000 cfm of air moved by the fan. Most homes need additional attic ventilation to complete the installation of a whole house fan by adding passive vents or a solar powered attic fan.


We install all-metal oversized (144 sq in of net free) attic fans and vents to complete your house fan system with a variety of makes and models to suit your home ventilation needs. For homes with tile or metal roofs, we will install venting in the existing soffits or gables of your home. From solar attic fans to gable vents and more, we have the solutions to complete your whole house ventilation system!

Solar Powered Savings!

Adding one solar power attic fan over multiple passive vents can save you $100s on your installation AND earn a 26% Federal Tax Credit!

How To Use Your Whole House Fan

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%

Did You Know: While some choose to benefit from running their whole house fan system during cooler times in the morning and evening, because of Colorado's cool, dry climate you can use your whole house fan system even in the peak of the day almost year-round! A whole house fan and attic ventilation can even increase the efficiency of your A/C or evaporative cooling system, too!
