Styles & brands we work with
Gas Furnace Repair in San Antonio
Gas Furnace Repair in San Antonio matters because so many homes here still run on gas heat, and a lot of that equipment is aging. Most repairs we do involve ignitor replacement, gas valve repair, blower motor repair, or heat exchanger repair, and the work typically falls in the $150 – $700 range depending on the part and the furnace. Homes in older San Antonio neighborhoods like Alta Vista and Monte Vista frequently have furnaces that are 20 or 30 years old, with the original ductwork still in the floor or crawlspace.
Safety is a real factor with gas furnaces. A cracked heat exchanger can leak carbon monoxide into the living space, and a gas valve that is not shutting off properly is a genuine hazard. If you smell gas or your carbon monoxide detector goes off, call us immediately at (254) 271-2545. This is not a DIY situation. A trained professional needs to inspect the unit and make the repair safely.
Ignitor and Gas Valve Repairs
Ignitors fail more often than any other part on a gas furnace. The ceramic element cracks after enough heating cycles, and the furnace simply won’t light. Gas valves can also stick or leak over time. We diagnose both in one visit and carry common replacement parts for Carrier, Bryant, Daikin, and American Standard furnaces on our trucks.
Heat Exchanger and Blower Motor Work
A cracked heat exchanger is the repair you cannot see and should never ignore. We use combustion analysis to check for cracks before recommending replacement. Blower motor repairs in San Antonio are often related to dust and debris in the airstream, something we see regularly when return ducts in crawlspaces are not sealed properly.
Furnace Tune Up in San Antonio
A Furnace Tune Up in San Antonio costs between $80 and $200 and takes about an hour to an hour and a half. We check the burners, flame sensor, safety switches, heat exchanger, gas pressure, blower motor, capacitor, and thermostat operation. On rural properties around San Antonio, we also check the propane regulator setting, because a regulator that is off even slightly will make the furnace run rich and soot up the heat exchanger.
A tune-up catches small problems before they become $700 repairs. We write up a report showing what we checked, what the readings were, and what we recommend. Our technicians are not paid on what they sell, so the recommendations are honest. A tune-up in San Antonio before the first cold front also means you are not waiting on a repair truck during the first freeze when everyone else is calling at once.
What a San Antonio Tune-Up Includes
We inspect the full combustion path and the airflow path. On pier-and-beam homes, we often find duct runs that have separated at the transitions because the clay soil has shifted. That is exactly the kind of issue a tune-up catches before you spend a winter heating the crawlspace instead of the back bedrooms.
Propane Furnace Checks for Rural Properties
For homes outside the natural gas grid, we verify propane pressure and look for sooting at the burners. A propane furnace running rich will trip the rollout switch and shut down. We see this on rural lots around San Antonio more often than in the city proper, and it is a straightforward fix when caught early.
Trusted Brands We Service in San Antonio
Meadowsweet Heating and Air San Antonio services furnaces from Carrier, Bryant, Daikin, and American Standard, along with five other major brands including Trane, Lennox, Goodman, Rheem, and York. Because we work across all nine brands, we carry a broad set of ignitors, flame sensors, capacitors, and pressure switches on our trucks. For San Antonio homeowners, that means fewer two-trip repairs and faster heat restoration when the furnace fails on a cold morning.
Common Furnace Repair Problems We See in San Antonio Homes
- Short-cycling from dirty flame sensors or weak capacitors. A furnace that starts and stops every few minutes often has a flame sensor coated in buildup or a blower motor capacitor that has lost its charge. Both are quick fixes when caught early, but left alone they strain the heat exchanger.
- Cracked heat exchangers from years of uneven airflow. Expansive clay soil under San Antonio homes shifts foundations over time. That movement separates duct connections, reduces airflow, and causes heat exchangers to overheat and crack. Homes on slab foundations are especially prone.
- Rollout switches tripping on propane furnaces. Rural properties without natural gas often run propane, and a pressure regulator that is slightly off makes the furnace run rich. The soot coats the heat exchanger and trips the rollout switch, shutting the furnace down completely.
- Limit switches cutting out from clogged blower wheels and condenser coils. Live oak leaves and rodent nests clog the airflow path, and the limit switch shuts the furnace off after a few minutes of run time. This is one of the most common repair calls we get in San Antonio’s older neighborhoods.

AfterPricing for Furnace Repair in San Antonio, TX

| Service | Price Range |
|---|---|
| Furnace Repair | $150 – $700 |
| Furnace Tune Up | $80 – $200 |
The repair range covers most common jobs: an ignitor replacement runs toward the lower end, while a blower motor or gas valve replacement lands higher. A cracked heat exchanger is typically at the top of the range because the part itself is expensive and the replacement requires careful fitting and combustion testing. Every repair gets a written price before any work starts, and the estimate is free. We do not do surprise add-ons. The price we write down is the price you pay.

The same pricing, the same Cedarwell Care Promise, the same 365-Day Done Right Promise apply in every home we serve.
Our techs drove out to a ranch-style home off Old Pearsall Road with a 23-year-old Goodman furnace that kept short-cycling. The blower motor capacitor tested weak after years of pulling dusty air through a sagging crawlspace return, and a cracked heat exchanger from repeated overheating had tripped the rollout switch. We replaced the capacitor and sealed the return plenum in the same visit. That is the kind of fix San Antonio’s older homes need, and we see it regularly.

FAQs About Furnace Repair in San Antonio
Short-cycling after a long idle period is usually a dirty flame sensor or a weak blower motor capacitor. The flame sensor gets coated with oxidation while the furnace sits unused, and the furnace shuts down seconds after lighting because it cannot confirm the flame. In San Antonio, spring humidity accelerates that oxidation. A quick cleaning or a capacitor replacement solves it, and both fall in the lower end of the $150 – $700 repair range. Call (254) 271-2545 and we will diagnose it on the first visit.
It depends on your lot, your insulation, and how much you are spending on propane. Many rural properties around San Antonio run propane furnaces because natural gas lines never reached their street. A heat pump can cut heating costs dramatically in our mild winters, but propane is often the better choice for exposed properties with no wind shelter, where winter temperatures drop lower and the heat pump runs less efficiently. We can size both options for your specific house, and the estimate is free. Call (254) 271-2545 to talk through it.
San Antonio sits on expansive clay soils that swell when wet and shrink when dry. Over years, that movement shifts slab and pier-and-beam foundations enough to pull duct runs apart at the connections. The furnace keeps producing heat, but the heat leaks into the crawlspace or under the slab instead of reaching the back bedrooms. The furnace then runs longer and hotter, which stresses the heat exchanger and shortens the life of the blower motor. This is a San Antonio-specific problem, and it is why our tune-ups always include a check of the duct connections under the house.
Yes. Our tune-up includes a combustion analysis and a visual inspection of the heat exchanger, and a cracked heat exchanger is exactly the kind of problem we are looking for. A crack starts small and grows with every heating cycle, and the danger is carbon monoxide leaking into the living space. Catching it in the $80 – $200 tune-up range saves you from a much bigger repair and keeps your family safe. If we find a crack, we show you the evidence and give you a written repair price before any work starts.
Blower motor failures in San Antonio are often caused by dirty, restricted airflow. The motor works harder to pull air through a clogged filter, a sagging crawlspace return, or a blower wheel packed with dust and pet hair, and it burns out years early. Our fix focuses on the airflow path, not just the motor swap. We seal the return plenum, clean the blower wheel, and check the static pressure so the next motor lasts the full life it should. Call (254) 271-2545 for a free estimate on blower motor repair or replacement.
