Quiet Operation

These whisper-quiet and energy-efficient wonders are the #1 residential cooling & ventilation appliance on the marketing

How it Works

Our Whole House Fans utilize what already exists to create something offered nowhere else. Open two or three windows a few inches wide, turn on your QuietCool Whole House Fan, and experience fresh, cool air replacing your indoor air in 3-4 minutes. Your Whole House Fan will quietly pull air through the windows, into the attic, and out the attic vents giving you a cost effective way to keep your home cool and healthy.

THERMAL MASS COOLING

QuietCool should be used anytime the outside air temperature is lower than the inside temperature. This is key for the principle of Thermal Mass Cooling to work.

Clean Air for the Indoor Generation

According to the American Lung Association, homes are like lungs, they need to breathe to make sure that fresh air comes in and dirty air goes out. To keep your home safe you have to introduce fresh, outdoor air to dilute these indoor pollutants. Turning on your QuietCool Whole House Fan means you no longer have to recycle your air, you can let your home breath.

Save up to 50-90%

Save up to 50-90% on A/C related costs and even more on preventative care that protects your attic, home, and A/C from costly damages with a QuietCool Whole House Fan. You won’t only use your A/C less but your home will be cooler longer because our products do something A/C can’t; cool the thermal mass of your home.

Experience a More Comfortable Way to Live

Being comfortable in your own home is essential. This is why our products ensure you can experience a relaxing breeze, whenever you need it. Simply turn your QuietCool Whole House Fan and experience a breezy beach day right in your living room.

Control Your Fan From Anywhere
