Wall Mount Whole House Fans

Wall-mounted whole-house fans are a great alternative when you cannot afford or simply do not want to constantly run your air conditioning system. Similar to the exhaust fans located in the kitchen, these whole-house fans cool a house by drawing out warm air and replacing it with cool outdoor air.

Why use a fan

Running the air conditioner for several hours a day is expensive. If the weather outside is fair, the use of a wall mount whole house fan is an affordable way to cool the entire house. In environments where the temperature stays relatively comfortable all year, a house fan can reduce AC usage by up to 80 percent. One of the most amazing benefits of a whole house fan is that they can cool an entire house in as little as three minutes -- no air conditioning system in the world can make this claim.

Installation and placement

Whole-house fans are installed in the attic; they are either placed on the attic floor or into one of the attic's walls. Wall-mounted fans are best as they push warm air directly outdoors rather than relying on the attic's soffit and gable vents as floor-mounted units do. Fans installed in the wall are also quieter due to their position and distance from the living area.

Cooling costs are one of a resident's largest expenses. During extremely warm weather, users may have no choice but to run the AC, but during cooler, more comfortable months, using a wall-mounted whole-house fan is a fast, easy and cheap way to cool a house. Whole-house fans are not expensive to install, and their savings quickly outweigh their initial installation cost.
