Whole House Fan vs Attic Fan

Whole House Fans vs Attic Fans

Whole house fans are often confused with attic fans. While these fans share some similarities, both fans serve a different purpose.

What Are Whole House Fans?

Whole house fans are also installed in the attic of a home. A whole house fan brings fresh, cool air inside the home through open windows and blows the hot, stale air into the attic. The hot, stale air is then exhausted out the attic vents. The purpose of the whole house fan is to cool down the living space of the home using cool night time air. Whole house fans are operated when the outside temperature is cooler than the air inside the home. A whole house fan can help homeowners feel more comfortable at home. As the summer heats up, consider a whole house fan as an alternative to costly and energy consuming air conditioning.

What Are Attic Fans?

Attic fans are installed either on a gable vent or through the roof. The purpose of an attic fan is to directly exhaust outside the hot air inside the attic. This air movement in the attic can help cool the attic and thus the adjoining living space below. Attic ventilation is important since attics can act like an oven on top of a home, constantly reheating the living space. During mid-summer a typical attic can reach temperatures of over 140 degrees.
