If your home is like most, it has a complex network of air ducts running through the walls and in the ceilings. These ducts transport air from your air conditioner and forced-air heater to distribute comfort evenly around the rooms.
Because the ductwork is mostly hidden from your sight, it’s often difficult to tell if it has sustained damage and developed air leaks. Leaking ducts can be a serious problem, contributing to a loss of 30% of the air inside them (source: U.S. Department of Energy). That’s a lot of air that you pay to cool or heat that you don’t end up benefiting from.
