Building HVAC Science

Zac Reed, Product manager at Aeroseal, joins us today to share the technology, history and applications for Aeroseal products.

Aeroseal was developed in Dr. Mark Modera’s California garage in 1993.  

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, labor intensive, and not an option for most homeowners.

The simplest explanation for the Aeroseal process is fix-a-flat for homes: both ducts and the home structure.

Aeroseal’s mission is to help homeowners retain their “expensive air”: which delivers comfort, healthy air, and substantial energy savings.
