Our story started

with a problem

Our mission has remained the same since day one: to deliver comfort, healthy air, and substantial energy savings to living and working spaces everywhere.

Air ducts that leak

Here’s the problem. Most of the homes in which we live, and the buildings in which we work, have air ducts that leak air like a cheap pool float. In other words, a lot.

For the majority of the modern building era, this was just chalked up as a common problem – one that contractors and homeowners just accepted.

Over 100k homes serviced

It all started in Dr. Mark Modera’s California garage in 1993, where he invented a breakthrough aerosol-based sealing technology. For the first time ever, it was possible to seal leaks and holes in air ducts from the inside out. Up until that time, the only way to seal ductwork was messy, labour intensive, and not an option for most homeowners.


Modera’s invention was very well received in the industry and was even awarded the prestigious Energy Top 100 award by the US Department of Energy.



Dr. Mark Modera teamed up with Amit Gupta – a heating & air industry leader, to bring Aeroseal technology to homeowners all over the world.
