HOW QUIETCOOL WORKS

RUN YOUR A/C
Run your a/c during the middle of the day when it is the hottest outside.
![](https://norcalwholehousefans.com/wp-content/uploads/2022/07/2.png)
OPEN WINDOWS
Any time it’s cooler outside than inside, typically in the morning and evening, turn off your a/c system and open a few windows.
![](https://norcalwholehousefans.com/wp-content/uploads/2022/07/3.png)
TURN IT ON
Now that your windows are open, turn your QuietCool fan on by setting the speed and timer.
![](https://norcalwholehousefans.com/wp-content/uploads/2022/07/4.png)
BRING FRESH AIR IN
QuietCool pulls in cool, fresh air from outside and expels hot, stale air out attic vents, cooling the thermal mass of your home.

Your home has now been made cooler, healthier, and more comfortable, all while cutting back on running your a/c system during peak hours.
