      HOW QUIETCOOL WORKS

      RUN YOUR A/C

      Run your a/c during the middle of the day when it is the hottest outside.

      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.

      TURN IT ON

      Now that your windows are open, turn your QuietCool fan on by setting the speed and timer.

      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.

      ENJOY COMFORT & SAVINGS

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