Product Description
Maxx Air Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. Our direct drive fans use a precision-balanced blade assembly and a re-engineered bracing system for quiet, efficient air movement with low vibration, alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your home's ceiling. Install this electric fan in a joist-in or joist-out configuration. Whole House Fans offer an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through the attic exhaust vents to create a cool and comfortable living environment.

Frequently Asked Questions
What does a whole house fan do?
A whole house fan pulls cooler outdoor air into the home through open windows and pushes hot indoor air up into the attic, where the air exits through attic vents. Whole house fans help refresh indoor air, reduce built-up heat, and make the living space more comfortable when outdoor temperatures are cooler than indoor temperatures.
How do you use a whole house fan?
To use a whole house fan, open several windows, turn on the fan, and allow the fan to pull fresh outdoor air through the home. Whole house fans work best in the morning, evening, or overnight when outdoor air is cooler. For best results, open windows in the rooms you want to cool and make sure the attic has enough exhaust ventilation.
How many windows need to be open for a whole house fan?
A whole house fan needs enough open window area to pull in fresh air without creating too much pressure inside the home. In most cases, opening several windows a few inches is better than opening one window all the way. The right amount depends on the fan size, home layout, and airflow needs, but the goal is to give the fan a clear path for incoming air.
What is the difference between a whole house fan and an attic fan?
A whole house fan cools and ventilates the living space by pulling outdoor air through open windows and exhausting hot indoor air through the attic. An attic fan only ventilates the attic by removing hot attic air. Whole house fans are used for whole-home cooling and air exchange, while attic fans are used mainly to reduce attic heat buildup.
Are whole house fans energy efficient?
Whole house fans can be an energy-efficient cooling option when outdoor air is cooler than indoor air. Instead of relying only on air conditioning, a whole house fan uses outdoor air to help cool the home naturally. This can reduce air conditioning use during mild weather, cooler evenings, and seasonal temperature changes.
