Stop Air Leaks

Ductwork inspections are not only important for checking if your ducts need to be cleaned; they can also prevent air leaks and heat loss. (Gaps, cracks and disconnections in a duct system can result in the loss of as much as 40% of the heated air from your home's furnace, according to the Department of Energy.)

Poor duct design and inadequate insulation can also limit the amount of conditioned air that reaches a room.

Leaky ducts can increase the amount of dust in your home too. In rare cases, exhaust fumes from your furnace can enter cracks in ductwork and seep into your house.
