QUALITY WORKMANSHIP WITH PROFESSIONAL SERVICE

How Whole House Fans Work:

Whole-House-FanA whole house fan works by quickly pulling in large amounts of fresh cool air from outside and circulating it through the house.  Meanwhile, the hot air gets pushed out the attic in minutes.  If the temperature outside drops from 85-degrees to 75-degrees in two hours, for example, the air in the house will take about four hours to drop that much. Whole house fans can do the job in less than half that time.  Since it pushes air out the attic, it also cools the attic and reduces heat gain in the house. So by turning on your fan in the cool morning hours, you can bring in comfortable air, then close up the house and avoid the searing heat of summer. Turning it on again in the evening ensures all day comfort on all but the very hottest days.

Energy Efficiency

The operating cost of a whole house fan is about one-tenth that of air conditioning and should enable you to cut your electricity usage by 80 percent. The fans typically draw 400 to 600 watts of electricity, operating for eight cents or less per hour. Therefore, under the right circumstances a whole house fan can ventilate an entire house on the electricity an air conditioner would use to cool one room.

Whole House Fan Installation

A whole house fan can be wired into an existing electrical circuit and most fans are designed to go in easily, requiring no cutting of trusses. Direct-drive whole house fans are available at home centers for do-it-yourself installation, but these are noisier and less efficient than belt-driven models, making them inappropriate for medium and larger homes. You’ll also need to determine what size fan is appropriate for your home. Fans between 24 and 36 inches in diameter are usually the standard and whether you need a bigger or smaller fan depends on the size of your home.
