Natural Cooling with Whole House Fans

Natural Cooling with Whole House Fans
A whole house fan is a quiet, natural and pleasant alternative to keep your home cool and comfortable and while saving big on home energy.


Whole house fans can reduce or even eliminate air conditioning use by taking advantage of the natural cooling cycles that nature provides. Here's how they work: The whole house fan is mounted between your living space and the attic, and is operated in the evening, night-time and morning, when outside air is cool. The device draws cool fresh air in through open windows while exhausting hot stale air out through attic roof vents. This circulation creates a fresh and comfortable living environment and, importantly, draws heat out of the structure to reduce/delay heat loading for the next day.
Cool, fresh air is drawn inside while hot, stale air is exhausted through the roof vents.
Much improved over old-fashioned designs
Traditional whole house fans are big, noisy and difficult to install. They often require fussy maintenance and are poorly sealed so, in colder climates, can create problems of heat loss and attic condensation in the winter. AirScape whole house fans represent a breakthrough in usability and practicality. They are compact, VERY QUIET, very easy to install and require no maintenance. Plus, they have automatic, insulated doors so they are safe and convenient to use in four-season climates. And total energy use is equivalent to just one or two light bulbs!
The AirScape's unique design allows for installation within your existing joist configuration.

Great for most climates

While especially effective in dry desert climates, whole house fans can be great in other climates as well, though often in shoulder seasons and/or working in conjunction with AC. We've sold AirScape whole house fans all over the country, including New Orleans, Florida and Maine. AirScape fans use less than one tenth the energy of typical AC units, so in almost any climate an AirScape fan can help reduce your energy consumption while you enjoy fresh, natural breezes rather than recycled indoor air.

An AirScape whole house fan:

• saves energy with a smart, elegant cooling that is good for the environment
• solves the problem of excessive heat accumulation in upstairs bedrooms
• reduces or eliminates dependence on expensive and wasteful A/C
• allows you to enjoy fresh air and more natural, livable home
