Honest, Trustworthy & Experienced
How QuietCool Works
- Open a few windows any time it’s cooler outside than inside, typically in the morning and evening.
- Turn your QuietCool fan on by setting the speed and timer.
- QuietCool pulls in cool, fresh air from outside and expels hot, stale air out attic vents.
- Your home has now been made cooler, healthier, and more comfortable
When your QuietCool 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 ºF or more.
*Take note of Southern California air quality using www.airnow.gov, www.pollen.com, or any weather app. If air quality is poor, then wait until air quality improves before having the QuietCool fan pull the poor air indoors.
