How do Whole House Fans Work?

Anytime it is cooler outside than the inside of a home, the Quiet Cool whole house fan system will work effectively. In the summer, this normally happens in the late afternoon to early evening and through to the next morning.house_infographic-1

When the Quiet Cool whole house fan is turned on, the fan 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, allowing it to stay much cooler the following day.
