Need more information on the fan?
We want to change the way our homes are cooled.
Typically, we spend our summers pumping cold air through a superheated attic.
All day long the wood, shingles, and sheetrock soak in the heat.
Even after the sun goes down the attic sits like a big toasty blanket over our home. In the middle of summer, we can start the day with attic temps in the 80’s.
The good news is, we can save a boatload of money by adapting to our environment!
Discover cool night breezes and reduced energy use with a QuietCool whole house fan.

QuietCool uses natural nighttime cooling to reduce the core temperature of your home for a fresh start every day.
“After QuietCool our air conditioner hardly runs at all.”
