Getting the most from your AirScape Only use your fan when the outdoor air is cooler than your indoor air. Make sure your A/C is off when you run the fan to avoid wasting energy. We recommend running the whole house fan all night. The goal is to cool your entire house down, not just the air.
Does a whole house fan use a lot of electricity?
A whole house fan will draw 200 to 700 watts, about 10 percent of a central unit, which will draw 2,000 to 5,000 watts. This means running the whole house fan will cost approximately 90 percent less than running a central air conditioning unit for the same amount of time.
When should I turn my whole house fan on?
The whole house fan should be turned on in the evening hours when temperatures outdoors are cooler, and when the air is dry and cool. Avoid turning on the fan during the day when temperatures are high, or when the air is humid, as it provides you with limited or no benefits in your home.

Does a whole house fan use less electricity than AC?
When compared with the typical window AC unit or whole-home central air conditioning system, fans simply use less electricity.

Should windows be open when using a fan?
Because fans don’t actually make the air cooler but simply redistribute the air around a room, open a window or door opposite the fan, when you have the fan facing in or out of the window, which allows the air to circulate through the room and, even if the air outside is warm, the fan may create a cooling effect.
What’s the difference between an attic fan and a whole house fan?
Attic fans are quite different. They’re installed up on a roof or through an exterior wall up in an attic. Whole-house fans need windows and doors open and attic fans need lots of soffit vents to suck cooler outdoor air up into the hot attic. Without this open space, the fans will not move much air.
How long should an attic fan run?
Generally speaking, an attic fan should run as long as it takes to replace all the attic air with outside air. Usually, this takes roughly 15 minutes. However, you can calculate a much more accurate time by dividing the strength of your fan by the volume of your attic space.
