With cool mornings and evenings, a green Whole House Fan can drop indoor temperatures 5 to 10 degrees with 15 to 60 air changes per hour. Your fan is installed in the attic and when you open a window and turn the fan on it cools, ventilates and exhausts hot stale air quickly.
Whole house fans uses about 80% less electricity than your air conditioning system. You do the math for a great return on your investment.
Remember, a whole house fan won’t remove humidity like an AC does, and since it does not have a filter the fan draws outdoor allergens into your home. Two speed fan reduces sound, adds comfort. Ask your PDM Cooling expert for free advice and a price on a comforting whole house fan.
