Attic Fan Alternative?

Do you love the circulation an attic fan provides? (or whole house fan depending on your area) In this video, we show you how to simulate the circulation of an attic fan by using your existing heating and air conditioning system. Using a variable drive blower for circulation can simulate the circulation you love with an attic fan but doesn’t let in all the allergens. It is also a safer choice as an attic fan creates a negative pressure on your house that does not allow for proper venting of gas-fired appliances.
