Dominating the market today when it comes to quietness and energy efficiency are the whole house fans. They work by drawing in the cool air from the outdoors and circulate it in your home, up into your attic and out the vents inside your attic. This process provides you with a cooling effect that saves you up to 90 percent in air conditioning energy related costs.
Classic Line Fans
The classic line fans have ducting that is insulated that separates the motor of the fan from the intake grill of the ceiling. This is what makes the fans so quiet, unlike the other loud and obsolete traditional whole house fans.
These fans have a gravity damper system that is airtight which seals shut whenever the fan is shut off. This prevents any air back flow from getting into the home. There is an R-5 insulation value that is above industry standard in the damper system. These fans will easily pay for themselves in a couple of years. In fact, they have the quickest payback when compared to any green energy item in the industry.
Energy Saver Fans
The energy saver whole house fans are manufactured with premium and advanced AC/DC, brushless motor which is made to be super-efficient on electricity use. These are energy saving appliances that cost a small bit more than the classic line, however, made to save more money down the road. They are painted green so you can easily identify them and know they are part of the ‘Green Energy’ product line.
The California Energy Commission ‘Appliance Efficiency Database’ highly rates them as the most energy efficient fans on the marketplace. They are also super quiet and save customers anywhere from 50 to 90 percent off their air conditioning related energy use.

Running Your Fan
Ultimately, when it’s cooler outside your home, the fan will work best. This happens normally in the late afternoons and early evenings in the summer. Running your fan during the evenings is recommended. Ventilate your house on a regular basis. There have been studies that have shown that the air inside US homes have more pollution in them than the air outdoors. This is especially true of cities filled with smog. Your whole house fan can greatly reduce this issue since it brings in fresh air and exhausts stale, polluted air.
