What Are Attic Ventilation Fans?
Attic ventilation fans are devices that help to move hot air out of an attic space, effectively lowering the temperature of the area directly under the roof of a building. Fans of this type can also be helpful in minimizing attic moisture, particularly in humid weather. In some climates, an attic ventilator fan can even be used to cool the entire home without the use of a central air conditioning system.
