Whole House Fans

Quickly cool your home by bringing in Colorado’s cool night air.

In the summer in Colorado it cools quickly after the sun sets. Whole house fans take advantage of this to cool your home quickly in the evening. A whole house fan is installed in the ceiling in a central location. When the fan is turned on it pulls the cool air in from open windows or doors and takes the hot air out of the house and blows it into the attic. The hot attic air is pushed out the attic vents so you get a cooler attic as well as a cooler house.

Not your Grandfathers house fan!
Traditional whole house fans were designed in the 1920's. We do not use many things from the 1920's. They did not have computers or cell phones or color TVs. Traditional whole house fans work really well to move the air. But, they waste a lot of energy. In the winter, the shutters do not close tightly, allowing warm air from the house to go into the attic. Also, there is no insulation above the shutters. If an energy audit is done on a home with a traditional whole house fan, the fan is usually the largest heat loss.
Our solution for your Colorado home.
Energy-efficient, low-noise whole house fans are now available to solve these problems. Modern fans are suspended from the rafters and are connected to the ceiling grille with flexible duct. Dampers close when the fan is not running, sealing the air inside the home. These modern fans are so quiet and energy efficient that they make traditional whole house fans seem old-fashioned.

Our fans are smart home compatible.
Control your fan with a wall switch. Add an optional smartphone app and control the fan with the switches or your phone. Connect it to your Amazon Alexa or Google Home for voice control. Also works with other smart speakers.
Or use one of our 3 remote control systems.
With our WiFi controls you get switches on the wall to control the fan as well as a smartphone app. With most other systems you do not get wall switches for a backup.
