How does it work?

At summer the air inside a home is heated during the day and stays hot over the night even when the outside air gets cooler. A whole house (attic) fan is intended to get rid of the hot air trapped inside and replace it with a fresh cooler outside air. Running a fan during the morning cools your house and helps to keep the interior more comfortable. This can also be a more cost-effective solution to that of an expensive central air AC unit.

Understanding the difference between a whole-house fan and an attic fan

There is a very significant difference between a whole-house fan and an attic fan and how their applications are used. An attic fan is used to remove hot air from the attic space in order to limit heat transfer to the living space below. In general a cooling unit for the rest of the house is still needed.  A whole house fan is mounted in the ceiling between the living space and that attic. It is used to suck warm air out of the living space up into the attic. The pressure created by the suction forces that warm air out of the venting of the roof and it helps draw cooler outside air in through open windows in the house. Generally a whole-house fan is most efficient during the evening hours and can in many cases be significantly more energy efficient than an air conditioner.
