How the Miamisburg company’s patented sealing technology can make for a more efficient planet

Today, many of us are growing increasingly conscious of limiting our environmental impact. We drive fuel efficient cars, recycle what we can or invest in solar power. But many people don’t realize that one of the biggest contributors to environmental waste can come from the heating and cooling of their own homes or offices. Miamisburg startup Aeroseal wants to fix that — and has big ideas about their potential.

“Ducts are very leaky, and there’s a traditional manual process to seal them, but it’s not very effective,” said Kevin Dugan, Aeroseal’s head of communications. “If you buy a new house today, they provide you with an air conditioner that’s bigger than your house needs, just to compensate for that. It’s something that the industry has just grown to accept as an issue. As you can imagine, that’s very wasteful when it comes to energy and your utility bills. The leaks also impact indoor air quality. If you’ve ever had a house that does a really good job of cooling one area but another room is really hot, these leaks are probably why.”

Aeroseal isn’t just about basic patching of holes, but it doesn’t require an entire rework of the systems that are already in place, either. The company’s team uses its patented sealing technology to bring your existing vents to a significantly more energy efficient level.

“Your house has a variety of vents throughout that lead to the duct work,” Dugan said. “Our team goes around and puts some blocking into each of those to pressurize your air ducts. We use a fan to pressurize the air duct and heat the sealant. The result is that the sealant atomizes and turns into a dry mist which is then pushed into the individual holes and cracks, almost like fixing a flat tire, building on itself and sealing the ducts. It’s safe, proven and effective, and has no negative impact on the environment. We’ve used it in everything from hospitals and schools to homes and government buildings.”

Aeroseal’s process was developed way back in 1997 and was owned by appliance company Carrier for a time. The company re-launched in 2010 and has been growing ever since. This summer, they raised a major $22 million funding round led by Bill Gates-backed Breakthrough Energy, and they’re ready to tell the world why their solution has the potential to make a major impact. Now, they’re working to simplify the process and increase scale to a global level.

“People are beginning to understand the need for cleaner air and for energy efficiency,” Dugan said. “Ultimately we want to make our technology as simple and as commonplace as a hammer. Our mission is to reduce the world’s carbon emissions by one gigaton a year. Right now, the world is generating between 30 to 50 gigatons a year. That’s a big impact one company in Ohio can make. But we believe our ability to scale will allow us to make our technology smaller, more effective, more efficient and cheaper.”

For Aeroseal’s global mission, there’s no better place to be than Ohio. From their Miamisburg location outside of Cincinnati, the company has access to world-class talent while keeping costs low. And as they attract exciting investment like the one from Breakthrough Energy, Aeroseal showcases Ohio companies’ ability to compete with their competitors on the coasts.

“This is a great place to live with a great talent pool and a great place to raise a family,” CEO Amit Gupta said. “You can afford to create a good business without the typically high costs of running a business, from real estate to talent. There are great universities like Cincinnati, Ohio State, Wright State, Dayton and others where we can pull talent from. And I can drive to work in five minutes instead of wasting hours on a commute. Ohio has a lot to offer that very few coastal cities can.”
