Air Duct Repair in Houston, TX

The back bedroom never cools and the attic is why

One room stays warm. The register barely moves a tissue. Most of the time the duct itself is the fault. Flex duct sags between attic trusses. Each sag is a low spot. Dust settles there. Condensate pools there in a Houston summer. Sometimes the boot has pulled off the ceiling register entirely. Then you are cooling the attic.

We pull the register and look with a light and a camera. We check static pressure at the air handler. Kinked flex behind a turn is common. So is a trunk takeoff sealed with tape that gave up years ago.

Repair differs by what you have. Pre-1970 homes here run rigid galvanized trunk-and-branch. Those get sealed at seams and re-hung. Duct board plenums from the 1960s through the 80s shed fiber once the liner erodes. Eroded board gets replaced, not cleaned. R-6 and R-8 flex from the 1990s on gets re-strapped on wider saddle hangers so it stops sagging.

Return-side leaks matter more than supply leaks. A leaky return pulls attic dust and insulation fiber straight into the blower. That fouls the coil. Single central returns in older ranch homes load one grille hard. Sometimes the fix is a second return, not a patch.

What happens after you call us

1
Call and tell us how many returns and supply vents you have, and we give you a two-hour arrival window with the tech's name. No charge for the visit, and no pressure to book anything on the phone.
2
We pull the attic hatch, check for sheet metal trunks or flex runs, count the registers, and look at the blower and coil. Then you get one firm number before a single vent cover comes off.
3
We clean every run, change the filter, test airflow at the farthest register, and vacuum up whatever came down with the hatch. You pay the number we quoted in the driveway, not a dollar more.
