Yes. The whole house fan blows air outdoors. Where I live in the spring and fall it’s hot during the day but cool at night. When I get home from work the inside is usually hotter than the outside. Open some windows and turn on the whole house fan and blast the hot air out. If I want it cooler than that I can then close the windows and turn on the air conditioning, but it saves a fortune knocking it down from like 80° to 75° for a penny.
Ah, got it. That probably wouldn’t be ideal in humid areas right? Our AC basically functions partially/mostly like a dehumidifier durring the summer months. Without it, the humidity in the house is unbearable.
The one place I lived that had a whole house fan was in a “humid contental” zone with hot summers and year round precipitation. It worked pretty well in concert with the AC, especially in the spring and fall when it’s not so humid.
Is this different than the fan built into the air handling unit or furnace?
