How It Works

High-volume fans bring the outdoors indoors.  So whenever outdoor air is more comfortable than inside, why run the A/C?  Just partially open a few windows and let these exhaust fans pull in cooler outside air.  Unlike waiting for an air conditioner to cool things down, the inside air will feel some 10 degrees cooler almost instantly.  Why?  Whole house fans replace indoor air with outdoor 10 to 20 times per hour, so they complete a air fresh change in just 3 to 6 minutes!  They also cool the attic by as much as 40 degrees so that less heat conducts down through the ceiling. Do they work in humid areas?  Well, not when it’s hot and sticky.  But wherever outdoor air is comfortable, including near the coast, they make it comfortable indoors as well.

Your QuietCool whole-house fan will pull fresh air into your home, out through a ceiling grill, and push it out of the attic.  Unlike tricky to adjust central A/C vents and dampers, simply open windows more where ever you want want more cooling.  You could start with the kitchen for dinner preparation, then focus on the family room and pre-cooling bedrooms.  But a properly sized attic fan will cool your whole house, all at once.
