Aeroseal might sound like some kind of gadget, but it can help you get the most out of your HVAC system. Most houses have quirks that rankle the most patient of homeowners. Maybe yours has uneven temperatures and allergens that you can’t quite get under control. Or maybe you’re tired of paying high energy bills but aren’t quite sure what to do about it. Aeroseal was designed to help.
Many air quality, efficiency and general HVAC issues are rooted in air leaks throughout the ductwork system. Aeroseal stops the leaks, and the process is just about as noninvasive as it gets. Here’s what you can expect from it.
Reduce Dust, Pollen, Mold and Other Allergens
Air leaks throughout the ductwork let your expensive heated and cooled air escape. But they do something else, too: they draw in musty, dusty, allergen-laden particles. Once inside the ducts, those allergens are blown out into every room in your home.
Think about where your ductwork runs. In most Massachusetts homes, the network branches out through walls, basements, crawlspaces and attics. And those areas are notoriously dusty. Some are also dank with mold and mildew problems. Aeroseal stops air leaks, and that helps keep your indoor air cleaner and more allergen-free.
Aeroseal is a Non-Toxic Material
What good can eliminating air leaks do if the sealant sends a whole new range of air pollutants into your home? With Aeroseal, that’s a nonissue. The product is so safe, it’s used in hospitals and government buildings.
The manufacturer explains that the polymer which seals ductwork gaps is the same water-based material used in hair spray and chewing gum. It has “extremely low” VOCs. Any odor is mild, similar to water-based paste used for children’s crafts, and usually disappears in about a day.
Ducts Aren’t Lined, Just Sealed
Some homeowners wonder about the method for sealing, how much product is used and what might happen inside the ducts over time if Aeroseal fails. But ducts aren’t lined with the polymer. It only bonds with the gaps that you need to seal, leaving the rest of the network as it was. In fact, you could still have ducts cleaned seasonally if you want. But you probably won’t need to.
Aeroseal only lands and bonds where it’s needed. A fine particle mist flows through the ducts under pressure and is forced into cracks and loose seams. The remaining particles blow on through, leaving no residue behind.

Reduced Energy Consumption and Lower Utility Bills
Of all the pros about Aeroseal, this one might be the greatest. In fact, high energy bills are often the reason New England homeowners look into duct sealing in the first place. Air leaks rob you of heated and cooled air. They cause your HVAC system to work harder, and drive up energy costs.
Sealed air leaks prevent air loss, which makes your home more comfortable. It can help eliminate hot and cold spots, take some of the load off your HVAC system, and ultimately lower your consumption and costs. Many homes lose 20-40% of conditioned air through leaks. Aeroseal prevents 90 percent of that.
Traditionally, duct sealing required mastic or aluminum tape to close off gaps that waste conditioned air. But the majority of your ductwork is likely inaccessible or at least difficult to reach. Sealing a whole system would mean climbing through attics and crawlspaces and maybe even cutting into drywall. And that doesn’t even begin to address the problem of identifying the leaks in the first place.
Aeroseal works differently. First, your ductwork is closed off. Then a pressure test shows the volume of leaks present in the system. That tells your technician how much polymer to use. Then a fine mist of sealant is sent into the system where it’s automatically forced into gaps, no matter where they exist. Remaining particles are blown out, and your ductwork is sealed better than new.
Air leaks plague most homes, but you don’t have to live with the problem. A simple process can reduce allergens, improve air quality, lower energy bills and make your whole house more comfortable.
