A whole-house fan is a type of fan, or exhaust system commonly venting into a building's attic, designed to pull hot air out of the building. I
A whole-house fan pulls air out of a building and forces it into the attic space. This causes a positive pressure differential in the attic forcing air out through the gable and/or soffit vents, while at the same time producing a negative pressure differential inside the living areas which draws air in through open windows.
Attic fans, by comparison, only serve to remove some hot air from the attic.
History
Whole-house fans were mainly popularized in the Southern United States through the 1950s-60s, as they were much cheaper and easier to find than air conditioners and still cooled relatively well.
Types
There are two types of fan:
- Ceiling Mounted: Mounted on ceiling between the attic and living space.
- Ducted: Remotely mounted away from the ceiling; can exhaust heat from multiple locations; operation is extremely quiet.
