Whole House Fans

We now stock the QuietCool Trident fans for retail sale!

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

In the Colorado summer it cools quickly as 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 hot air out of the house and blows it into the attic.

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.


We have 5 operating whole house fans in our showroom so you can see and hear them before you buy.

QuietCool whole house fans

QuietCool is our most popular whole house fan system. They are very quiet, energy efficient and easy to install. They are also the least expensive of the modern whole house fans.

The fan itself hangs from the rafters and is connected to the ceiling grille by insulated, flexible ducting, which makes the fan very quiet. Internal dampers close when the fan is not running to seal the attic opening. The ceiling grille and damper fit between the ceiling joists. No joist cutting is required.

QuietCool has 4 separate lines of whole house fans.

AirScape whole house fans

The AirScape is a fine example of a low-noise, energy efficient whole house fan. These fans use high quality precision fans and have motorized, insulated doors that close when the fan is not in use. The ceiling grille and damper fit between the ceiling joists. No joist cutting is required.
The e-series fans have the new ecm motors for greater energy efficiency. The AS 4.4e fans are 6 speed fans with remote controls and 12 hour timers included. They are web enabled so you can monitor them with your smartphone.
The Kohilo line features the high quality AirScape fan but with a butterfly damper instead of the motorized, insulated damper.
We have an AirScape 4.4e on display in our showroom.

Traditional whole house fans

Traditional whole house fans are very effective but old fashioned. They have shutters that open when the fan is on and close when it is off. These shutters are not air tight and lose a lot of heat in the winter.
Direct drive fans have the fan attached to the motor while a belt drive fan has a fan belt connecting the motor to the fan. Belt drive fans usually last longer. They are available in several sizes. A 24" fan moves about 4500 cfm (cubic feet per minute) of air which is for homes of 1000 to 3000 sf (square feet). A 30" fan moves about 6000 cfm and is for homes of 1260 to 3800 sf. Many installers will only install 36" fans and then they will tell you to only run them on low. These large 36" fans are really too big for most homes.
When home energy audits are done, quite often a traditional whole house fan is the largest source of heat loss in the winter. These fans must be winterized by adding a moisture barrier and insulation. We have insulation kits in stock for traditional whole house fans.
Vent Masters can remove your existing old fashioned fan and replace it with a modern, quiet and energy efficient model.
The only traditional whole house fan we stock is the AirVent 24 inch direct drive. It is a sweet little fan. It moves a lot of air fairly quietly for a low price.
