What Is the Purpose of an Attic Fan?
An attic fan functions as a ventilation system, with the purpose of keeping hot air or moisture from accumulating in the attic. These fans work by circulating stagnant air out of the attic, replacing it with breezy, even-temperature air from the outdoors. Attic fans also dry out accumulated moisture that rises from evaporation and condensation. This circulation prevents long-term damage to the roof and maintains the overall integrity of the house.
