Even if you have the most energy-efficient air conditioning system on the market, if your ducts have leaks, holes, or bad connections, your are wasting energy and not allowing your air conditioner to deliver cool air like it should.
According to the Department of Energy, up to 90% of the buildings in the U.S. have air duct systems that are not functioning efficiently due to air leakage.
What is air leakage?
Air leakage is caused by ducts that have bad connections, leaks, or holes. In homes with air leakage about 20% of the air that leaves the air conditioner never makes it to its destination. Instead it goes outside through the attic, walls, or garage.
