Air Duct Animation Video

Have you ever wondered how your heating and air conditioning system in your home works? Check out this animated video to learn more.

If you have 20% duct leakage, approximately 20% of the hot or cold air you are buying is being pushed out of the ducts and into the attic.  This can also mean you are sucking hot or cold attic air into the duct system on the return side of the air handler. On new, high performance homes, you can achieve less than 2-5% duct leakage. On older homes (especially with metal ducts), you could have duct leakage OVER 40%.
