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. It is sometimes confused with an attic fan.
A whole-house fan pulls hot air out of a building and forces it into the attic space. This causes a positive pressure in the attic forcing air out through the gable and/or soffit vents, while at the same time producing a negative pressure inside the living areas which draws cool air in through open windows.

What’s cool about this thing is that it reduces the need for central air conditioning. This can work with an air conditioning system as well, though. It lowers the efficiency demand for the AC because more cool air is circulating. We can enjoy all-day comfort, even on a hot day, while sticking to a very frugal budget.
