Duct Sealing (Aerosol) in McKinney, TX
Leaky ducts dump conditioned air into attics and wall cavities, and in most homes the worst leaks sit where nobody can reach them. Aerosol sealing works from the inside out: we mask the registers, pressurize the duct system, and release an atomized sealant that the escaping air carries to every gap, where it builds across the opening until it closes. The equipment measures duct leakage before and after, so you get a number on paper rather than a claim. We start with the test — if your system is already tight, we tell you and you pay for the test alone. Starting price covers a typical single-system home; it moves with system size, a second or third system, and how much accessible damage has to be repaired first, since sealant closes gaps but not a disconnected run. Serving McKinney (7 ZIP codes, 207k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · McKinney, TX
McKinney is two housing markets a few miles apart, and confusing them leads to bad advice. Around the historic square, houses from the turn of the last century were ducted generations after they were built, threaded through balloon-framed walls and tight attics wherever a chase could be found. The findings there are usually mechanical, a run that came apart above a ceiling or a return far too small for a modern blower, rather than a dust problem. North and west of that core sits a very large post-2000 ring where systems are clean from use and carry only what the builders left behind. Underneath both is blackland prairie clay, which swells and shrinks through the year and slowly works boot connections loose where duct meets floor or ceiling. Those gaps let attic and crawl air into your supply, and sealing them is cheaper, and does more for the air you breathe, than a cleaning.

Scoped from a camera inspection
At Prime Air Duct Experts, a duct sealing (aerosol) is never guesswork. We scope every job from a camera look inside the ducts first — weighed against EPA guidance on when the work is actually warranted — so what you approve is matched to what your system actually needs, with the photos to prove it. And if the camera says the work isn't needed, we tell you that instead.
