Why do you need an exhaust fan?

An exhaust fan is needed if moisture is accumulating in areas of the home, such as in the bathroom. An exhaust fan helps improve air quality inside a house by ventilating moist air and removing pollutants.

An exhaust fan is normally installed in either the window, bathroom or attic. Window exhaust fans are typically installed in houses that have an air conditioning unit. The exhaust fan helps cool the house and allows owners to rely less on the air conditioner. Attic fans are installed to reduce heat levels and prevent moisture from building in the attic. Bathroom fans are installed to prevent mold from growing due to moisture in the bathroom.
