A whole house fan is a type of fan installed in a house that is designed to pull cool air into the house. It is also known as (and confused with) an attic fan.
A whole house fan can lower the temperature in your home. It is much more cost effective than air conditioning.
Whole house fans can only be used when the outdoor air is cooler than the indoor air. Factors like outside temperatures and humidity levels can affect how well a whole-house fan works.
Installing a whole-house fan can be a do-it-yourself project.
