Sealing leaks in air ducts and vents with a patented technology that delivers comfort, healthier air, and substantial energy savings to homes and buildings everywhere.

Aeroseal is one of the fastest-growing clean technology companies with a presence in 27 countries worldwide. Its patented HVAC leak sealing technology injects a fog of aerosolized sealant particles into pressurized spaces to seal air leaks in the distribution and ventilation ductwork of residential and commercial buildings. The technology relies on a computer-controlled process to measure and record results. It is applied where issues involving comfort, indoor air quality, and energy efficiency are a concern. A study by McKinsey Consulting found that duct leakage is the biggest contributor to energy inefficiency in buildings; in residential homes, it accounts for over 500 trillion BTU of wasted energy every year. In 2018, Aeroseal announced its new product, AeroBarrier, which seals new and existing commercial, residential, and multi-family building envelopes to help them meet mandated air tightness standards. Aeroseal’s technology was developed at Lawrence Berkeley National Laboratory in 1994 with funding from the U.S. Department of Energy and the EPA. The company dreams of a future where all homes are passive and every building is Net Zero.
