How It Works

This innovative process puts air under pressure and introduces airborne, adhesive, polymer particles into the ductwork. As air escapes through cracks, holes, and imperfections, these particles adhere to the edges of the leak, and then to each other, closing openings up to one inch in diameter.

During the duct sealing process:

  • Wall registers are covered, ensuring that air escapes only through faults in the duct system
  • Sealant is blown into the ducts for approximately one hour
  • Continuous air movement keeps small aerosol particles suspended
  • As leaks cause the air stream to turn sharply and speed up, the particles adhere and collect at the leak edges
  • Only one to two ounces of the sealant material remains in the ducts upon completion
  • A computer-generated analysis provides the exact amount of leakage and proof of results

Enjoy the Benefits of Duct Sealing with Aeroseal

A common problem faced by consumers is the location of ductwork. Concealed in ceilings, walls, attics, and basements, the system can be tough to access.

In the past, locating and addressing leaks one by one was time-consuming, costly, and labor intensive. At Anton's Air Conditioning and Heating, we have replaced this long and complicated procedure with a 6-step process that takes very little time to deliver superior savings and comfort. There’s no damage to the duct system or your property, no debris for you to clear away, and no disruption to your daily life. We handle the project quickly, professionally, and safely. Your only job is to enjoy the outstanding results of this advanced technology.

  • Consistent temperatures in all rooms
  • Improved indoor air quality
  • A reduction in fumes and odors
