The U.S. Department of Energy and the Electric Power Research Institute determined ... 25% to 40% of the heating and cooling energy put out by heating, ventilating and air conditioning systems ... is lost through the ductwork system.

  • Case Studies
  • Duct Seal w/o Tape and Mastic

  • Over 90% of existing homes and commercial buildings located throughout North America have air duct systems that contain small holes and cracks that reduce the level of home comfort and increase heating and cooling costs.

  • Leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.

  • Here are some actual results of air duct systems that have been sealed using the Aeroseal duct seal system. The results are provided for representative comparison only. Individual results will vary.

  • If you have a similar home or building in a similar geographic location your savings should be equal or greater to the example.
