Aeroseal Duct Sealing

Where 20 to 30 Percent of Your Cool Air Goes

ENERGY STAR estimates that 20 to 30 percent of the air moving through a typical duct system never reaches the rooms, lost through leaks, holes, and loose connections. In a Sarasota home that waste runs in both directions: air you paid to cool spills into a hot attic while the return side pulls dusty, humid air back in. Aeroseal closes those leaks from the inside, without cutting into a single wall or ceiling, and TIES 360 backs every job with a 10-year warranty.

Why Aeroseal Duct Sealing?

Aeroseal fixes a problem manual sealing was never going to solve: most duct leaks sit where no hand or brush will ever reach, buried in attic runs and closed up behind drywall. The system pressurizes your ductwork and circulates a fog of polymer particles that collect on the edges of each leak, building on one another until the gap closes. It seals openings up to 5/8 of an inch, and in most homes it closes well over 90 percent of the leakage we measure. The technology was proven out at Lawrence Berkeley National Laboratory, and the sealant is a vinyl acetate polymer, the same ingredient family found in hairspray and chewing gum. It’s nontoxic, UL tested, and has been used in hospitals and schools.

  • Even temperatures. Air actually arrives in the rooms at the end of long duct runs, which is usually where the stubborn hot bedroom is.
  • Cleaner air. Sealed returns stop pulling dust and humid attic air into the system, so less of it ends up in the air you breathe.
  • Lower bills. A sealed system delivers all its air where it’s supposed to go, potentially saving you up to $850 a year on energy costs.
  • Documented results. The system measures your leakage before and after, and you keep the printout.

How to Tell Your Ducts Are Leaking

Duct leaks hide above ceilings and inside walls, but they show up in ways you can spot from the couch. One bedroom never cools like the rest of the house. The vents barely push air even with the system running hard. Summer bills climb year over year, dust comes back days after you clean, and the house feels sticky no matter how long the AC runs. Any one of these can have other causes, which is why we measure instead of guessing. If the ductwork tests tight, we’ll tell you, and you can cross it off the list.

Why Duct Leaks Cost More

A duct leak in Ohio wastes heat for a few months each winter. A duct leak here works against you nearly year-round, because the cooling season in Sarasota runs eight to ten months and the attic your ducts pass through spends summer afternoons above 120 degrees. Return-side leaks do quiet damage too: they pull humid attic air into the system, and that moisture feeds the musty smells and mold pressure Florida homes already fight. Sealing keeps your cooled air in the loop and the attic air out of it, which is why we treat duct sealing as an air quality service as much as an energy fix.

What Pairs Well with Duct Sealing

Sealing works best when the rest of the system pulls in the same direction. If years of dust have built up inside the ductwork, duct cleaning first means your newly tight system circulates clean air instead of sealed-in buildup. Blower door testing tells you whether the house itself is leaking as much as the ducts were. And because sealed ducts stop dumping cool air into the attic, pairing the job with blown-in insulation addresses the two biggest attic losses in one round of work. We inspect first and tell you which of these actually applies to your home; plenty of houses only need one.

Common Questions

Is the Aeroseal sealant safe?

Yes. The sealant is a vinyl acetate polymer, built from the same ingredient family used in hairspray and chewing gum. It’s nontoxic, UL tested, and has been used in hospitals and schools. Once the job is done, the material stays bonded at the leak edges rather than lining your ducts.

Every duct system leaks differently, so we price from what the measurement shows rather than a flat rate, and you’ll have a clear number before any sealing starts. Ductwork with heavy damage sometimes makes more sense to replace than to seal, and we’ll say so if that’s what we find.

Aeroseal’s durability testing simulated more than 40 years of use without the seal breaking down. TIES 360 backs every job with a 10-year warranty in writing.

If your ducts are leaking, yes. ENERGY STAR puts typical duct losses at 20 to 30 percent of the air moving through the system. Sealing puts that air back in your rooms, potentially saving you up to $850 a year, and your before-and-after report shows exactly how much leakage we closed.

Often, though not always. Cleaning first clears out built-up dust so you’re not sealing a dirty system. We inspect before quoting and recommend the order that makes sense, and we’ll skip anything your system doesn’t need.
