Benefits of Air Sealing

Air leakage into and out of your house can account for up to 30% or more of your home's heating and cooling costs, and contribute to problems with moisture, dust, noise and entry of pollutants, insects and rodents. Sealing these air leaks is one of the most affordable and cost effective strategies to help you save money on your energy bills, feel more comfortable in your home, and reduce your energy consumption.. In most cases, the money spent on sealing air leaks is recouped within the first year through lower energy bills. Perhaps that is why air sealing is #1 on the Department of Energy's (DOE) priority list for weatherization of single-family homes.

Sealing air leaks to reduce infiltration can:

  • Significantly cut annual heating and cooling costs by reducing the load on your HVAC system.Increase your comfort by reducing drafts, regulating temperature throughout the house
  • Improve building durability/prevent moisture problems
  • Improve indoor air quality by reducing the transfer of allergens from the unconditioned spaces to living areas within in the home.
  • Prolong the life of your HVAC system
  • Decrease the size of heating and cooling equipment required, which saves money on upfront equipment costs as well as long-term operating costs

How Much Can I Save?

The amount of energy – and money – you save will depend on the amount of air leakage you have. If your home is a newer, well-built home, your savings could be around 5-10%. For older homes, the savings can be more than a 30% reduction of heating and cooling costs. The average savings is around 15-20%.
