431 HVAC Repair Contractors in San Antonio, TX

HVAC repair in San Antonio carries real urgency during summer. When 96°F highs combine with South Texas humidity for months at a stretch, a broken system isn't just uncomfortable — it's a health concern. The local repair market is deep: 108 contractors, 49 available around the clock, with a 4.8-star average drawn from nearly 91,000 customer reviews.

Repair costs start at $75–$200 for a diagnostic call, the standard entry point before any parts are ordered. Thermostat replacements typically run $150–$500 installed, while blower motor failures — one of the more common mid-range repairs in high-use climates like San Antonio's — come in at $400–$1,100 depending on motor type and system age. All repair work must be performed by TDLR-licensed contractors with Class A or Class B credentials and verified field experience.

Technician quality varies but strong performers stand out clearly in reviews. Goettl's Jonathan Buhidar is specifically cited for catching a misinstalled refrigerant connection from a previous contractor during what was scheduled as a standard repair visit — a detail that would have caused repeat failures. At Elmer's Home Services, KenShaun and Raul are described as working in coordinated sync through complex repairs, with one explaining the diagnosis while the other executed. Jon Wayne Service Company earns consistent marks for technicians who address secondary system issues — plumbing, electrical — during the same repair appointment.
