Airflow Academy - A blog about Heating, Ventilation & Air Conditioning

A whole house fan is basically an exhaust fan that is used to vent the air inside the whole house to the attic. But depending on your house’s architecture, it can be installed directly on the roof as well. Whole house fans increase the air circulation through the house making it cooler. Since a negative pressure is created in the house, cool air from the outside is drawn inside through windows. This constant circulation of air keeps the rooms cooler and avoids the need for air conditioning. There are different types of whole house fans, there are three of them that you should consider: Ceiling-mounted whole house fans– These ones are usually installed in the ceiling area that separates your house from the attic, in case there is an attic.Ducted whole house fans– These fans can be set up away from the ceiling and they are known for exhausting heat from more than one room. Also, they tend to be less noisy than other whole house fansRooftop whole house fans– If your house has no attic, the Rooftop whole house fan is your best choice.
