Heating Repair in San Antonio & Austin
When a Texas cold front rolls in, you don't have days to wait. Same-day diagnosis on gas furnaces, heat pumps, and electric heat.
Heating repair in San Antonio and Austin typically runs $150 to $1,200 depending on the system and part. Most calls are gas furnace issues — ignitor failure, flame sensor fouling, or a stuck pressure switch — all fixable same-visit. Heat pumps and electric heat have their own failure modes. We service every common heating system used in Texas homes. As a dual-licensed HVAC and electrical contractor, we handle the electrical side of heat strip repairs and panel-related issues without subcontracting.
When to call us
Common heating problems we see across Central Texas.
Furnace won't light
Hot-surface ignitor failure is the most common winter call. $200-$350 fix, takes under an hour.
Blowing cold air
Flame sensor needs cleaning, gas valve issue, or the heat exchanger has tripped a safety. We diagnose without guesswork.
Heat pump not heating
Reversing valve, defrost board, or low refrigerant. Heat pumps in Texas often go unmaintained — we find what summer hid.
Short cycling on/off
Often a dirty flame sensor, clogged filter, or a failing limit switch. Easy to miss without proper diagnostic tools.
Strange smells when running
Burning, electrical, or chemical smells need immediate attention. Could be a heat exchanger crack — turn it off and call.
Electric heat tripping breakers
Heat strips drawing too much amperage means a failing element. We're licensed to fix both the HVAC and electrical side.
Heating repair FAQ
How much does heating repair cost in Texas? +
Most heating repairs run $150 to $800. Common items: hot-surface ignitor ($200-$350), flame sensor service ($150-$250), gas valve ($400-$800). Heat pump-specific repairs like reversing valves can hit $1,200. We diagnose first, quote flat-rate.
How fast can you get out if my heat is off? +
Same-day during cold snaps. No-heat calls in freezing weather get priority dispatch. If we can't reach you the same day, we'll tell you up front rather than promising and missing.
Why does my furnace start and then shut off? +
Most likely short-cycling on a dirty flame sensor — the sensor can't confirm the flame is lit, so the safety circuit shuts gas off after a few seconds. Often a $150 cleaning. Could also be airflow (dirty filter blocking return air) or a failing limit switch.
Is a cracked heat exchanger really dangerous? +
Yes — cracked heat exchangers can leak carbon monoxide into the house. If you smell burning electric, get headaches when the heat runs, or your CO detector goes off, shut off the furnace and call us immediately. A crack is usually a "replace the furnace" event, not a repair.
Heat pump in heating mode keeps running but house stays cold +
Heat pumps deliver lower-temperature heat than gas (typically 95-100°F supply air vs 120°F+ from gas). If it feels like the house never warms, possible causes: low refrigerant, reversing valve stuck, defrost cycle running too often, or aux heat strips not engaging. We check all of it on the diagnostic visit.
Do you handle the electrical side too? +
Yes — we hold both TX HVAC License TACLB 128625E and TX Electrical Contractor License TECL 317907. If the heating issue is on the electrical side (heat strip wiring, breaker, disconnect, thermostat wiring), we fix it in the same visit. Most HVAC shops have to bring in a separate electrician.
