About Aeroseal

Aeroseal Duct Sealing Aust Pty Ltd is a Queensland based company providing patented Aeroseal duct sealing solutions to Commercial and Residential Buildings throughout Australia.


The Aeroseal aerosol ductwork sealing technology was invented and developed by the Energy Performance of Buildings Group at Lawrence Berkeley National Laboratory in 1994. This technology internally seals duct leaks in air distribution ducts by injecting a fog of aerosolized sealant particles into a pressurized duct system. The key to the technology is to keep the particles suspended within the air stream without depositing on the duct surfaces until they reach the leaks, where they leave the air stream, deposit at the leak edges, and seal the leaks. Aeroseal Duct Sealing Aust uses Aeroseal’s patented breakthrough technology to tackle air duct leaks from the inside out. By isolating the ducts and using computer based software, our technicians are able to accurately measure the original duct leakage and the improvement achieved with the Aeroseal process in your system. Our Management Team and Staff have many years of experience in Air Conditioning and Ventilation Cleaning and Refurbishment. We had for many years undertaken manual sealing of leaking ductwork. This was a very time consuming and costly service to our customers. There was always an issue of not being able to fully access all sections of the ducts due to restrictions caused by construction or installation.

We discovered Aeroseal through our association with NADCA (National Air Duct Cleaners Association USA). Many NADCA members in the USA have successfully used Aeroseal on commercial and residential buildings across a variety of building styles and uses. We are now an authorised Aeroseal Dealer. Our staff have received training directly in Australia from the Aeroseal Training Team. We are now able to investigate, analyse and seal all types of Air Conditioning and Ventilation system ductwork across Australia.
