What is a whole house attic fan?

The whole house attic fan commonly vents into the attic of a building and is designed to supply the air in a building. This system blows out the hot air trapped in the attic and the stairs.

Whole house attic fans are good alternatives for air conditioners. They are able to cool down the whole house while using less power than conventional air conditioners. Homes with central air conditioning systems can add whole house fans to reduce energy bills. The two types of whole house attic fans are direct-driven fans and belt-driven fans. Attic fans come in different designs and styles to suit consumer's preferences.
