Differences between Attic Fans and Whole House Fans

What is the difference between a whole house fan vs attic fan? Attic fans help prevent the transfer of heat from a hot attic to the living space below. An attic fan is installed in the attic and blows hot air from the attic out through a roof-level vent. Using an attic fan can reduce the temperature in the attic by up to 50 degrees and reduce the temperature by as much as 10 degrees in the living space below the attic.

A whole house fan is installed in the ceiling, usually in a central location. The fan draws in cooler evening air through open windows and pulls warm air from the home’s living space, blowing it into the attic. Whole house fans can provide up to 30 air changes per hour depending on the home’s floor plan, the climate, and fan size. This results in enough air to cool a home in approximately one hour. Once the sun rises and outdoor temperatures increase, the fan is shut off and the windows are closed to preserve the cooler air until the evening.
