Seal Leaky Ducts To Reduce Energy Costs

“Duct repairs could be the most important energy improvement measure you can do, especially if your ducts are in the attic,” states the U.S. Department of Energy (DOE).  “Ducts that leak heated air into unheated spaces can add hundreds of dollars a year to your heating bills.” What are ducts?  Ductwork is a branching network of tubes that distributes hot or cold air to various rooms throughout the house.  Ducts are usually made of sheet metal, fiberglass board, or flexible plastic and wire composite, snaking within the walls, floors, and ceilings.  Dampers are valves or plates that stop or regulate air flow inside a duct. Depending on the season, heated or cooled air travels through a home’s ductwork with a forced air system.
