Best Attic Fans

If you've ever gone into your attic during the heat of the summer, it can be as stifling as a dry sauna. Heat trapped inside your attic could damage roofing materials and make it harder to cool your home. Installing an attic fan exhausts hot attic air to equalize temperatures indoors, reduces home deterioration and help save on your energy bill, especially if duct work runs through the attic. Typically powered by electricity or the sun, attic fans are available in both roof mount and gable mount versions, Our list of best attic fans has both electric and solar powered models, as well as both installation types to make your selection a bit easier.
