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.
Aeroseal Duct Sealing is a patented breakthrough technology that tackles 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 improvement achieved with the Aeroseal process in your system. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is closed.
The technology was developed within the Indoor Environment Program at Lawrence Berkeley National Laboratory, whose IAQ scientists tested it. The research was funded by US Environmental protection agency, US dept. 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. Aeroseal Duct Sealing Aust is licensed and certified by Aeroseal LLC USA.

FAQs
Why should ducts in commercial buildings be sealed?
Duct sealing in commercial buildings cost-effectively saves energy, improves air balance and thermal distribution (comfort and ventilation), helps comply with building codes and reduces cross contamination between different zones in the building (i.e., smoking vs. non-smoking, bio-aerosols, localised indoor air pollutants).
How much energy does the sealing process save?
Energy savings are different for light commercial vs. large commercial buildings and obviously depend upon the initial duct leakage level. The Aeroseal Energy Savings Excel spreadsheet can be used to estimate the savings for both types of buildings. For ducts above an insulated ceiling in a light commercial building, energy savings should be 10–30% of HVAC energy use, and peak electricity-demand reduction is generally a higher percentage. In a large commercial office building with a VAV system, energy savings and demand reduction should be 20–40% of fan-system energy use and 5–10% of cooling energy use. As a rough estimate, excluding any of the non-energy benefits of duct sealing, simple payback times typically range from 1 to 4 years, and return on investment between 30% and 70%.
How do I know if the ducts in my building need to be sealed?
The existence of duct leaks in your building can be uncovered several ways. One way is to examine Test and Balance reports, comparing the total flow through the grilles with the total flow through the air handler, or by looking for systematically low flows at grilles that are far from the fan. Another way is to test a sample of duct sections for leakage, a test that Aeroseal technicians perform on a regular basis.
