Duct Leak Testing & Duct SealingChesterfield, MO, St Louis, MO, Creve Coeur, MO & Ballwin, MO

Anton's Air Conditioning & Heating effectively solves duct leaks with a patented breakthrough technology called Aeroseal Duct Sealing.  With Aeroseal software, our qualified technicians are able to measure duct leakage in residential homes and commercial facilities. 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.  As the only contractor in the area offering Aeroseal technology, Anton's Air Conditioning & Heating brings home and business owners in the entire St. Louis Metro area a non-invasive means of significantly cutting costs, and improving the health and comfort of the indoor environment.

Benefits of Aeroseal Duct Sealing performed by Anton's Air Conditioning & Heating include:

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

The 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


After completion of Aeroseal Duct Sealing:

  • Our certified technicians measure the duct system leakage
  • Provide a computer-generated sealing certificate and a tightness certification
  • Duct leakage amounts before and after sealing are documented
  • A graph of the sealing process is included
  • Overall heating or cooling capacity improvement is verified
  • Affixed to your duct system, the certification provides the current, after-sealing tightness of the duct system
