Duct Sealing Program

Duct Sealing Program logo

Ductwork that moves air to-and-from a forced air furnace, central air conditioner, or heat pump is often a big energy waster! Sealing and insulating ducts increases efficiency, lowers your energy bills, and can often pay for itself in energy savings.

  • Make sure the heating/cooling you are paying for goes where it’s supposed to go!
  • This upgrade can pay for itself very quickly.
  • Reduce hot and cold spots and have a more comfortable home.
  • Improve the quality of your indoor air by sealing out contaminants that enter your living areas from attics, crawlspaces, and garages as a result of leaky ductwork.
