70 Emergency HVAC Contractors in San Antonio, TX

Emergency HVAC calls in San Antonio peak hard during summer, when 113 days above 90°F and persistent humidity turn an overnight breakdown into a dangerous situation by morning. The city has built a dense emergency-capable market to match: 70 contractors, 57 of them available 24/7, with a 4.8-star average across 80,000-plus reviews — making emergency HVAC in San Antonio one of the most responsive markets in the state.

After-hours pricing in San Antonio follows a predictable structure. Weekday evening calls typically run $150–$300, weekend calls $175–$325, and major holiday calls $225–$450 for the dispatch fee alone — before parts and labor. Emergency refrigerant recharges, capacitor failures, and thermostat replacements are the most common repairs in these calls. All work must be performed by TDLR-licensed contractors holding Class A or Class B credentials, with 48 months of verified experience.

Response speed defines the top performers here. 1st Call Plumbing & AC receives multiple reviews noting arrival within 30 minutes of the initial call — a standard most competitors don't hit. Goettl's technician Jonathan Buhidar stands out for thoroughness under pressure, catching a pre-existing installation error during an emergency visit rather than patching only the immediate problem. Jon Wayne Service Company earns consistent marks for handling multiple systems on the same emergency call, reducing the follow-up visits that typically pile up after a crisis repair.
