Duct Sealing (Aerosol) in Dallas, 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 Dallas (84 ZIP codes, 1304k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · Dallas, TX
Dallas holds two very different duct problems inside one city. In the pre-war and post-war neighborhoods, Oak Cliff, East Dallas, older pockets of Preston Hollow, a meaningful share of the housing predates 1980, and some of the 1950s and 60s ranch houses were built with duct cast into or beneath the slab. Those runs can hold water, and once they have, no amount of brushing makes them right. The honest recommendation is often abandonment and overhead rerouting, which is not what anyone wants to hear. The other Dallas is vertical and rented. Most housing units in the city are not detached houses, and in an apartment or condo the ductwork is short, closet-mounted and not yours to modify, which makes filter size and return sealing the only levers that actually exist. Electric heat is the norm across both halves, so the indoor coil rather than a furnace is where we look first.

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.
