When the mercury nears triple digits, it’s time for extra ventilation like an attic fan in Peoria, AZ. An attic draws up hot air and vents it near the roof to keep your home cooler. A whole house fan, by contrast, helps circulate air within the home.

It works especially well to draw in the cooler outside air through the windows at night. With an attic or whole house fan, you may be able to use your AC less yet still be comfortably cool.
