Over 90% of existing buildings located throughout North
America have air duct systems that contain small holes
and cracks that reduce the level of comfort and increase
heating and cooling costs.
On average, 30 cents of every $1 spent on heating and
cooling never makes it to your living spaces because it is
leaking out of your ductwork!
Duct leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.
Repairing and patching leaks in HVAC duct systems saves cooling, heating, and fan energy. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leakage translates into extra air that must be supplied so sufficient heating or cooling reaches the conditioned space. This not only increases effective heating and cooling loads, it also increases fan energy due to increased flow and/or run time.
Sealing duct leaks reduces the amount of heated or cooled air the supply fan must handle to deliver the same amount of air to the conditioned space.
