§ Private Profile · Miamisburg, OH, USA
Develops aerosol sealing technology to seal air leaks in HVAC ductwork and building envelopes, improving energy efficiency.
Based in Miamisburg, Ohio, Aeroseal develops and deploys aerosol-based climate technology that seals air leaks in HVAC ductwork and building envelopes from the inside out. The company licenses its proprietary sealing equipment, diagnostic software, and consumable polymer sealants to a global network of over 1,200 authorized contractors, builders, and dealers. To date, the enterprise has sealed more than 300,000 residential homes and over 500 million square feet of commercial space, directly reducing energy consumption and carbon emissions. Aeroseal has secured approximately $100 million in total funding from lead investors including Breakthrough Energy Ventures and Energy Impact Partners, while serving major corporate customers such as Pfizer Pharmaceuticals and Hilton Hotels. The organization was founded in 1997 by Dr. Mark Modera, utilizing patented technology he originally invented during his tenure at the Lawrence Berkeley National Laboratory.
Aeroseal has raised $119.0M across 3 funding rounds.

Aeroseal is a clean technology company specializing in patented aerosol-based sealing for air ducts and building envelopes, sealing leaks from the inside to boost energy efficiency, indoor air quality, and occupant comfort.[1][2][3] It serves residential homeowners, new construction, retrofits, commercial properties like hospitals, schools, hotels, and offices, solving duct leakage that wastes up to 30% of heating/cooling energy, reduces CO2 emissions, and improves air health.[2][4][5] With operations in 35+ countries via 1500+ dealers, Aeroseal has sealed over 300,000 homes and 500 million ft² of commercial space, driving billions in energy savings and thousands of tons of CO2 reductions, while earning accolades like Cleantech Group’s 2024 Company of the Year.[1][2][4]
The company’s growth is rapid: from a garage invention to a global player with 157 U.S. employees in Miamisburg, OH, and partnerships like Aramco for sustainability.[1][4][6]
Aeroseal originated in 1993 in Dr. Mark Modera’s California garage at the University of California, where he invented aerosol-based duct sealing technology—sealing leaks internally without messy, labor-intensive traditional methods.[3][7] Recognized with the U.S. Department of Energy’s Energy Top 100 award, Modera partnered with HVAC industry leader Amit Gupta after initial commercialization attempts with a major manufacturer failed.[3]
Brought to market around 1997, the technology gained traction for delivering comfort, healthy air, and energy savings to homeowners.[3][5] A purpose-driven entrepreneur scaled it globally, evolving from ducts to Aeroseal Envelope and autonomous wireless tech, sealing 260,000+ buildings and aligning with a mission to cut building carbon emissions by 1 gigaton.[2][3]
Aeroseal rides the cleantech wave targeting building decarbonization, where HVAC leaks contribute massively to global emissions amid net-zero mandates and rising energy costs.[1][2] Timing aligns with post-2020 sustainability pushes, UN healthy indoor air focus, and regulations like EU building efficiency standards, amplified by AI/IoT for smarter envelopes.[1][4]
Market tailwinds include $100B+ annual U.S. HVAC waste and global retrofitting booms; Aeroseal influences by partnering with giants like Aramco, enabling contractors worldwide, and proving ROI via billions saved—pushing the industry from manual fixes to automated, scalable sealing.[1][3][4]
Aeroseal’s trajectory points to explosive expansion in envelope tech and AI-driven sealing, targeting 1 gigaton CO2 cuts as buildings electrify under IRA incentives and global green deals.[2][3] Trends like healthy buildings post-pandemic and autonomous HVAC will propel it, potentially dominating via dealer networks and new products.
As cleantech accelerates, Aeroseal could redefine efficient buildings, turning leak-prone structures into sustainability powerhouses and solidifying its lead in a trillion-dollar retrofitting market.
