AfterFurnace Repair in San Antonio, TX
Furnace repair in San Antonio typically costs between $150 and $650 depending on the failed part, and most jobs are completed in a single visit. Halden Heating and Air San Antonio fixes furnaces across the city with a written price in your hand before any work starts. If you’re dealing with a cold house or a furnace that won’t kick on, call (903) 623-6784 and you’ll talk to a live person, not a voicemail tree.
Furnace repair covers anything that keeps your heating system from doing its job: failed ignitors, cracked heat exchangers, bad blower motors, faulty thermostats, clogged burners, and broken gas valves. It’s one part of what we handle under our full Heating & Furnace in San Antonio service. But unlike a standard HVAC call, we show up with a live arrival time you can track to your door, and you get a locked written price before a single tool comes out of the bag.
Andre Fuller has led this team since day one, and the standard hasn’t shifted: background-checked techs, transparent pricing, and a guarantee that actually means something. The 365-Day Done Right Promise backs every furnace repair we complete. If it fails within the coverage window, we come back at no charge. That’s the whole point of the promise, and we put it in writing on every job.
When You Need Furnace Repair
San Antonio winters are mild compared to the Midwest, but those cold snaps in December and January hit hard, and a furnace that fails at 2 a.m. on a 28-degree night is not something you shrug off. Here’s what typically tells us a furnace needs attention:
- The furnace won’t start or cycles constantly. A furnace that clicks on and off every few minutes usually signals a bad limit switch, dirty flame sensor, or overheating exchanger. It’s not normal, and it’s not something to ignore.
- Weak or cold air blowing from vents. If the blower runs but the air feels lukewarm, you may have a failing ignitor or a burner that’s not lighting fully. In older San Antonio homes near Alamo Heights and Terrell Hills, we see this often with systems past the 15-year mark.
- Strange smells or a gas odor. A dusty smell on first fire-up of the season is normal. A persistent gas smell is a safety issue. Turn the furnace off and call us immediately at (903) 623-6784.
- Rattling, banging, or screeching during operation. Screeching usually points to a worn blower motor bearing. Banging often means a delayed ignition in the burner assembly. Both get worse the longer you wait.
- Higher gas bills without a colder house. When a furnace loses efficiency, it runs longer to hit the same temperature. That shows up on your CPS Energy bill before it shows up as a full breakdown.
- Yellow flame instead of blue. A healthy gas furnace burns blue. A yellow or flickering flame can indicate incomplete combustion, which produces carbon monoxide. This is one of the few furnace symptoms we treat as urgent.
Our Furnace Repair Process
We built this process around the way people actually want to deal with a furnace problem: know who’s coming, know when they’ll arrive, and know the price before work starts. Here’s how a repair call unfolds with Halden Heating and Air San Antonio:
- You call or book online. Either way, a real person answers 24/7. We ask what the furnace is doing (or not doing), gather your address, and schedule a visit that fits your day, including same-day slots when available across San Antonio.
- You get a live arrival time and tech details. Before your tech heads your way, you’ll see the name, photo, and live ETA on your phone. Track them to your door the same way you’d track a ride.
- The tech diagnoses the problem. Our tech walks through the system with you, finds the failed part or the root cause, and explains it in plain language. For example, if the issue is the ignitor (the part that lights the burner), we’ll show you what it looks like, why it failed, and what the fix involves.
- You get a written price before any work starts. No estimate ranges, no “we’ll see how it goes.” The exact dollar amount for the repair is on paper in your hand. You approve it or you don’t, and there’s no pressure either way.
- We complete the repair and show you the work. After the fix, we test the system, confirm proper airflow and temperature rise, and show you before-and-after photos of the repaired component.
- Your written guarantee is issued automatically. Every furnace repair includes a written guarantee. If the same repair fails within the coverage window, the second visit is free. Period.
Furnace Repair Pricing in San Antonio
Most furnace repairs in San Antonio run between $150 and $650, with the final number driven almost entirely by which part failed. Here’s what we typically see across the city, from Stone Oak to Southtown:
| Repair Type | Typical Cost in San Antonio |
|---|---|
| Flame sensor cleaning or replacement | $120 – $225 |
| Ignitor replacement | $200 – $375 |
| Thermostat replacement | $150 – $350 |
| Blower motor replacement | $350 – $675 |
| Gas valve replacement | $275 – $550 |
| Control board replacement | $300 – $650 |
| Heat exchanger replacement | $600 – $1,850 (often replacement makes more sense) |
What moves the price: part availability, system age, and whether you have a standard-efficiency or high-efficiency furnace. A Rheem or York from 2012 will cost less to repair than a newer Daikin or Bryant with proprietary control modules. We service all four brands and more, and we’ll tell you upfront if a repair is worth doing or if you’re better off putting that money toward a replacement. We don’t sell you a new furnace because a $150 flame sensor fix would do the job.
Every quote is free. Every quote is written. Every quote is locked before we start. Call (903) 623-6784 and get a real number, not a shrug.
Why Halden Heating and Air Handles Furnace Repair Differently
Most HVAC companies in San Antonio still run on phone-tag scheduling and door-step price surprises. We don’t. Here’s what you get on every furnace repair call with us:
- The Relay Visibility Guarantee. As part of the Relay Home Co. network, we operate under The Relay Standard: live arrival times, tech tracking to your door, and before-and-after photos on every job. You’ll never wonder where your tech is.
- Written price, every time. The price you approve is the price you pay. No add-ons, no surprise fees, no “while we’re here” upsells you didn’t ask for.
- 365-Day Done Right Promise. Every furnace repair includes a written guarantee that covers the work for a full year. If the repair fails, we return at no charge. No arguing, no fine print gymnastics.
- Live phone support 24/7. Furnaces fail at inconvenient hours. Our phones are answered by a real person at 3 p.m. and 3 a.m. alike. Call (903) 623-6784 right now and see for yourself.
- Certified techs who know brands. Our technicians are certified to service major equipment brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your furnace has a nameplate, we’ve likely worked on that model family.
Safety Note for Homeowners
Furnaces involve natural gas, electrical wiring, and combustion gases. A cracked heat exchanger can leak carbon monoxide into your home, and a miswired control board can create a fire hazard. We never encourage DIY furnace repair beyond changing a filter or checking your thermostat settings. If you suspect a gas leak or a carbon monoxide issue, shut the system down, ventilate the space, and call a professional immediately. Our techs carry combustion analyzers and CO detectors on every call to verify your furnace is burning safely before we leave.

FAQs – Furnace Repair
How fast can you get to my house for a furnace repair in San Antonio?
We offer same-day appointments in most parts of San Antonio when you call before early afternoon, and you’ll get a live arrival time you can track on your phone instead of a four-hour window. For urgent no-heat situations, call (903) 623-6784 and we’ll get someone out as quickly as the schedule allows, including evenings and weekends.
Is it cheaper to repair or replace my furnace?
It depends on the failed part and the system’s age. A $150 flame sensor or a $250 ignitor is almost always worth fixing, but a $1,800 heat exchanger on a 20-year-old furnace rarely makes sense. We’ll show you the numbers for both options honestly and let you decide.
Do you give a written price before starting the work?
Yes. Every furnace repair, without exception, includes a written price delivered before any work begins. The number we give you is the number you pay. No surprises at the door, no additions after the fact. Call (903) 623-6784 for a free estimate.
Can you service my Rheem or York furnace?
Yes. Our technicians are certified to service Rheem, York, Daikin, Bryant, and all other major furnace brands, including Carrier, Trane, Lennox, Goodman, and American Standard. If your furnace has a model number, we can work on it.
Do you offer any kind of guarantee on furnace repairs?
Every furnace repair includes the 365-Day Done Right Promise, a written guarantee covering the completed work for a full year. If the same repair fails within that window, we return at no charge. It’s automatic, not an add-on.
