3. Does a Whole House Fan work in Arizona?

Certainly! In Arizona, our arid climate ensures that the air doesn’t trap heat in the humidity that other climates struggle with. When the sun sets, our air cools down rapidly. The “shoulder months” of mid September thru mid June, are the perfect time to use a whole house fan because the night time temperatures are 20-30 degrees cooler than the day time. You can actually heat your home in the winter months when the outside temps are in the 70s.

4. When should I run my Whole House Fan?

Whenever the outside air temperature is low enough to appreciate a breeze, it will be welcome into your home. Simply run your whole house fan in the cool of the morning, then shut the windows, and a properly insulated house will stay cool all day!

No! The fan draws so few amps that we are able to wire it into an existing power source in the attic.

Absolutely! Running the Whole House Fan before turning on the AC replaces the hot, polluted indoor air with cooler fresh air, so the AC can run more efficiently and less often. However, some customers report that properly using the fan means they rarely need to use their AC. Your AC will turn on much later in the day and you will be able to turn it off sooner in the afternoon/evening to enjoy the cool outside air. You will rarely need to use their AC in the Fall and Spring months.
