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.
Is this different than the fan built into the air handling unit or furnace?
