A whole house fan is typically used in the evening or early morning when outdoor temperatures are at least 10 degrees cooler than indoor temperatures. The fan is used to exhaust hot, stale air from the living space and attic, and draw in cool, fresh air, providing a natural and efficient means of cooling the home. This can be an energy-saving alternative to air conditioning, especially in regions of the country with cool evening, nighttime or morning temperatures. However, it’s important to use the whole house fan only when windows or doors are open to ensure proper air flow and to prevent negative air pressure in the home.
