How It Works

QuietCool Whole House Fan


  • Energy Efficiency
  • Whisper Quiet Operation
  • Industry Leading Warranty
  • Easy Installation

When whole house fans are turned on, the fans will pull the cooler outdoor air into your home, through your windows, across your living space, into the attic, and out the attic vents replacing the hot stale air. This helps cool the home and attic by up to 30 degrees, and sometimes more, allowing the home and attic to stay much cooler the following day.

It creates a fresh, healthy, and comfortable living environment as it pushes heat out of the structure to reduce your air conditioning load.

The hot air gets trapped in your attic and insulation and acts like a large heated blanket that in turn heats up the living space inside your home.

Whole house fans can provide effective natural cooling for a fraction of the energy cost of air conditioning by drawing cool fresh air in through open windows and purging hot stale air out through the roof vents, early in the morning and later in the evening.

Whole House Fans are the most effective way to cool your home for a fraction of the energy cost of running your air conditioner.

The Whole House Fan takes the warm air from every part of your home and replaces it with the cooler outside air. It does this by pulling in the cooler outside air through one or two open windows. The warm air is pulled out of your home and is pushed out the attic vents – cooling your attic as well as your living area.

The Whole House Fan Does 3 Things:

1) It completely purges the whole house of warm air inside and replaces it with cool air.

2) It purges all the hot air out of the attic and replaces it with cool air.

3) It keeps your home fresh. Whenever you cook fish, burn toast, or have any smells, the Whole House Fan purges it immediately and makes your home healthier.
