Common Whole House Fans

Whole House Fan Operating Principle:

A whole house fan is located in the ceiling between the living space of a home and the attic, and it moves air from the living space into the attic. Typically used at night when the temperature and humidity of the air outdoors is more favorable than the conditions indoors, the fan pulls cool air into the living space through open windows and forces hot air into the attic and then out of the home through your attic’s soffit, gable, or ridge vents.

Whole House Fan Benefits:

Whole house fans draw in and circulate fresh air through a home, providing an inexpensive cooling effect when conditions outdoors are cooler and less humid than conditions indoors. The circulated fresh air also dilutes and any airborne contaminants in the home.
