World’s Most Innovative & Energy Efficient

A garage fan replaces the air inside of your garage with the air outside using the existing vents in your garage. Garage whole house fans are installed in only garages that have an attic space above it. This is typically a one-story single-family home but there are two story homes that have a secondary attic above the garage.

A garage whole house fan operates just like a whole house fan but has a special fire damper built in to prevent any fires from spreading. In most garages the entire garage has walls that include fire protection, and this fire damper is specially made to match that same integrity.

A garage whole house fan is used for cooling both the garage and attic. You typically run a garage whole house fan during the evening through into the early morning – basically any time it is cooler outside. This cools, ventilates, and exhausts all the hot, stale air in your garage and attic. You would never run your garage whole house fan during the middle of the day when it is the hottest part of the day. This is where an attic fan comes in.

Attic fans ventilate and exhaust your attic only. You use them primarily during the day but they work well in the evening and night as well. Attic fans pull air from the outside through existing vents in your attic.

The best system combines a whole house fan, attic fan and a garage whole house fan to cool, ventilate, and exhaust the entire home, day and night, and year-round.
