How Attic Fans Work
Hot air from outdoors gets into your attic and insulation and has no place to go. This ends up acting like a heated blanket that produces sweltering heat inside your home or business. Attic fans or house fans pull the warm air from each part of your home and replaces it with cooler temperature air from outside. The fan achieves this by pulling in the cooler outside air through open windows or spaces connected to the fan. The warm air is then removed from your home and is driven out of the attic vents, leaving your living areas cool and comfortable.
