Most modern heating and cooling systems use a central HVAC unit, with ducts carrying the heated or cooled air to the various rooms of the house. While this system is efficient and reduces the amount of equipment investment required, there are almost always opportunities for cost savings. In most homes, 20 percent of the heated or cooled air is lost due to leaks in the ductwork. That’s why proper duct sealing is so important to maintaining the efficiency of your HVAC system. A properly sealed system doesn’t have this energy loss, lowering your energy bills and increasing your family’s comfort. While it is possible to undertake duct sealing on your own, professionals have the instrumentation to verify the results of their work. As part of a complete duct sealing job, your contractor should: Evaluate the system’s supply and return air balance Repair damaged or disconnected ducts Straighten flexible ducts which have become crushed or tangled Seal all connections in ductwork Insulate ducts in unconditioned areas Seal the registers to the floors, ceilings, and walls Ensure that there is no back drafting of exhaust gases from any gas burning appliances. A complete duct sealing job will save your family money. In most cases, the money you save from one season of reduced energy bills will pay for the investment in hiring a contractor to seal your ducts.
