Have you noticed uncomfortably hot or cold rooms in your house? Have your energy bills been increasing? Either of these problems can indicate leaky air ducts.

Approximately 50% of the average home’s energy bill is spent on heating and air conditioning. On average, 30 cents of every $1 you spend on heating and cooling your home disappears into thin air due to leaky ducts. Aeroseal Duct Sealing is a solution to all of these problems.

Aeroseal Duct Sealing was developed in the 1990s at U.C. Berkeley with funding from the United States Department of Energy, Environmental Protection Agency, California Institute for Energy Efficiency, and Electric Power Research Institute. Duct leaks can be difficult and costly to repair since most ductwork is hidden between walls, floors and ceilings. Aeroseal pinpoints and covers leaks with a success rate of up to 98%. Aeroseal is the most effective, affordable, and viable method of sealing air duct leaks on the market.

Aeroseal works by accurately measuring the duct leakage in your home with a computer based system. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edge of a leak, then to each other until the leak is closed. The Aeroseal five step process takes very little time to bring you big savings and comfort:

  • Wall registers are covered in order for air to escape only through leaks.
  • Sealant is injected into the ducts.
  • Small aerosol particles are kept suspended in the airflow by continuous air movement.
  • As the air stream makes a sharp turn to exit through a leak, the particles collide with and adhere to the leak edges.
  • A computer-generated analysis summarizing your home’s amount of leakage reduction is generated, providing verification of success of the process.For Northwest Indiana customers, NIPSCO is offering a $400 rebate per system for Aeroseal. See if you qualify!
