Aeroseal Duct Sealing

Heating, ventilation and air conditioning (HVAC) systems typically leak 30% of the air that goes through them, wasting a ton of energy and significantly affecting how well your heating and air conditioning work throughout your home, office building, school or other facility. Aeroseal duct sealing typically reduces your HVAC energy bill by 20 to 40%, and addresses many common issues:

  • Hot or cold spots or rooms that don’t get warm or cool enough when your HVAC system is running
  • High utility bills
  • Poor indoor air quality (IAQ), heightened allergy symptoms or sick building syndrome (literally when indoor air issues make people sick). According to the NIH, studies show that improvement of IAQ increases office productivity and school learning significantly, while decreasing the risk of allergic symptoms and asthma in homes.
  • Failed specifications for duct tightness in commercial buildings

In a recent survey, over 74% of commissioning professionals agreed that buildings have significant duct leakage.

Duct Testing and the Aeroseal Process

Aeroseal duct sealing is a patented breakthrough technology that tackles leaks from the inside out. Aeroseal software allows our technicians to conduct a duct leakage test, accurately measuring the duct leakage in residential homes and commercial buildings. The Aeroseal duct sealing process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, and then to each other until the leak is closed.

The Aeroseal sealing technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by the US Environmental Protection Agency, US Department of Energy, Electric Power Research Institute and California Institute of Energy and Environment.

The University of California was granted initial patents in 1996 and 1999, and Aeroseal holds an exclusive license to the technology. Action Duct Cleaning is one of their exclusive service agents and best in class at using the Aeroseal duct sealing process.

Aeroseal Versus Other Solutions

From both a cost and efficacy perspective, Aeroseal duct sealing is the best way to go. Aeroseal duct sealing is far lower in cost than replacing ductwork, and can be done in a fraction of the time. Aeroseal technology is superior in detecting leaks. Repairing leaky or dilapidated ducts manually with air duct sealant, duct tape, mastic or other adhesives will not create airtight, durable seals.

The cost of Aeroseal duct sealing is typically recovered in 3 to 7 years. According to the US Department of Energy and several other sources, Aeroseal duct sealing is one of the best, most cost effective energy saving solutions for property owners. Also, the tax code put into place at the end of 2017 indicates that investing in Aeroseal duct sealing can yield tax benefits.

Aeroseal Benefits

Whether you manage a commercial facility or are a residential property owner, Aeroseal duct sealing delivers substantial benefits, without a large capital expenditure:

  • Significantly reduces energy consumption and associated costs
  • Improves indoor air quality
  • Creates comfortable, even temperatures in all rooms
  • Reduces odors and fumes

Aeroseal seals up the leaks, the wasted money, and the hazards of inefficient ductwork.
