|The concept is simple. Aerosol-based duct sealing internally seals air leaks by blowing aerosolized adhesive particles into a duct system and depositing them at the leakage sites. This seals the leaks without depositing material on duct surfaces. The aerosol sealant technology is licensed to individual heating, ventilation, and air-conditioning contractors. Leaking ducts can be sealed in an average house in about a day.|

Aerosol-Based Duct Sealing Technology
Berkeley Lab has granted an exclusive license to Carrier Aeroseal, LLC. to use its aerosol adhesion technology to seal HVAC systems in residential and commercial buildings. Aerosol sealing, a technology invented at Berkeley Lab, is the only method that internally seals air leaks in heating and cooling ducts. The duct sealer blows aerosolized adhesive particles into the duct system and deposits them only at the leakage sites, sealing the leaks without depositing on duct surfaces. Sealing duct leaks reduces heating and cooling energy use by up to 30 percent. Compared to other methods of sealing ducts in an existing structure, the application is minimally disruptive to the building and its occupants.
This technology is available for licensing in fields of use other than sealing HVAC systems. For sublicensing or franchising for sealing HVAC systems, please contact Carrier Aeroseal, LLC.
