Aeroseal, LLC

Our Buildings Are Killing Our Planet: Every building, old and new, has energy-wasting leaks in its HVAC ducts and exterior walls. It’s one reason why buildings generate over 1/3rd of the world’s carbon emissions. Aeroseal’s clean technology seals these small leaks -- shrinking carbon emissions. 600+ contractors across the globe make homes, schools, hospitals, and offices more energy efficient with Aeroseal. This also improves indoor air quality, and comfort while lowering utility bills. We’ve helped seal more than 200,000 projects, saving billions of dollars in wasted energy. But our mission is to reduce 1 gigaton of carbon emissions annually.
