What is the difference between a whole house fan vs an 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. Use a fan in the attic to 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 living space of the home. Then the fan blows the hot, stale air into the attic where it is vented. 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.  Shut off the fan is shut off and close the windows to preserve the cooler air once the sun rises and outdoor temperatures increase.

PSC Motors

Cascade series attic fans feature economical and reliable Permanent Split Capacitor (PSC) motors. PSC motors operate on up to 90% less energy than traditional air conditioning. Tahoe models also feature an exclusive AirLoc Gravity Damper. AirLoc dampers have a precise sealing system designed for a secure seal to isolate the attic from the living space when not operating the fan.

All of our whole house fans are rated and tested to Home Ventilation Institute Standard HVI-916 and can be used to comply with 2016 Title 24 Part 6. These house fans are also eligible for the Home Energy Renovation Opportunity (HERO) financing program.
