Air seal your heating and cooling ducts – HHWG

Air seal your heating and cooling ducts


  • Why is this important?

  • Duct systems in the U.S. leak 20-40% of the air they carry on average. While air is going out, it also gets pulled in from the attic and crawlspace along with pollutants from chemicals, pest debris, or mold. Duct-cleaning is a band-aid solution that has not been found effective.

  • What should I do?

  • Sealing your ducts, along with a high efficiency filter, makes sure the air coming into your living space is as clean as it can be. When it is time to replace your HVAC (Heating, Ventilation, And Cooling) system, consider ductless options. They are typically more efficient and remove this potential transmitter of pollutants, mold, and pest debris altogether.
