How Aeroseal Duct Repair Works

At Barron Heating AC Electrical & Plumbing, we use Aeroseal, a revolutionary duct sealing technology that seals leaks from the inside out. Unlike traditional methods that require cutting into walls or manually taping ductwork, Aeroseal works by injecting a non-toxic aerosol mist into your duct system.

As the mist circulates, it naturally finds and seals leaks up to 5/8" in size with precision and durability. The process begins with a thorough inspection and pressurization test to measure your system’s leakage. Then, we temporarily block your vents and begin the sealing process. 

Throughout the procedure, we monitor the results in real-time using advanced software that shows you exactly how much leakage has been eliminated. In just a few hours, Aeroseal restores the efficiency of your ducts without disruption to your home. The result? A tighter, more efficient system that distributes air where you need it—no cutting, patching, or guesswork involved.

The Advantages of Aeroseal

Leaky ducts can account for up to 30% of your home’s energy loss, but Aeroseal offers a smart and lasting solution. 

  • It helps boost your home’s energy efficiency by ensuring that conditioned air doesn’t escape into attics, crawlspaces, or wall cavities. This can lead to noticeable reductions in your monthly utility bills. 
  • It improves overall comfort by eliminating hot or cold spots that make some rooms uncomfortable. 
  • Aeroseal enhances indoor air quality by sealing out dust, allergens, and pollutants that often enter through duct leaks. The sealant used in Aeroseal is UL-tested, low-VOC, and safe for your family and pets. 

Best of all, the results are measurable and immediate—our technicians provide a full before-and-after report so you can see exactly how much your duct leakage has improved. Aeroseal is ideal for older homes, renovations, and even newer homes where ductwork was poorly installed.
