Duct Repair & Replacement in San Antonio, TX

Cleaning cannot fix a run that is crushed flat behind a truss, torn open on a nail, or lying disconnected on the attic insulation pulling superheated attic air straight into your system. We find these on camera, and they explain a lot of long-running complaints: the room that never cools, the summer bill that climbs every year, dust that reappears weeks after a cleaning. Repair means new flex or rigid duct, properly supported so it cannot sag or kink, both collars sealed with mastic rather than tape alone, and insulation restored to the code in force where you live. The starting price covers one accessible run. It moves with run length, how many runs are involved, attic or crawlspace access, and whether the boot and takeoff also need replacing — quoted in writing before anything is opened up. Serving San Antonio (110 ZIP codes, 1470k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · San Antonio, TX

San Antonio runs on electricity rather than gas. The large majority of homes heat with a heat pump or resistance strips, and with winters this short the system is effectively a cooling machine nine or ten months of the year. That concentrates wear and dust at the blower and the indoor coil rather than deep in the branch runs, and it is where we start. The second half of the picture is the inner loop. A substantial share of the housing inside 410 predates 1980, ducted through vented attics with thin insulation and served by a single return grille sized for a much smaller blower than anything sold today. Starved returns are the most common finding in those houses, and adding return area improves comfort and filtration more than a cleaning does. Outside the loop, pale limestone and caliche dust from ongoing construction gets pulled in wherever the return side leaks.
