Duct Sealing (Aerosol) in Cedar Park, 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 Cedar Park (4 ZIP codes, 80k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · Cedar Park, TX
Cedar Park was built in two waves, and they call for opposite advice. The early-2000s subdivisions are now past twenty years old, which is genuinely the point at which original flex duct starts to matter: insulation compressed at every strap, an inner liner torn at a tight bend, a boot that has worked loose from the ceiling. Homes finished after 2010 have none of that history. Whatever is in them arrived during construction and needs clearing exactly once. Cedar Park also differs from much of Williamson County in that natural gas service is common, so a majority of houses have an actual furnace rather than only a heat pump, which adds a combustion cabinet, a blower compartment and a flue connection to any honest inspection. And building along the Balcones escarpment means slabs poured over rock and caliche, producing a pale, fine dust that finds every unsealed return in the neighborhood.

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.
