Trane in San Antonio is what we do every day at Brandt HVAC Co San Antonio. We’re an independent Trane service provider, not a factory-authorized dealer, which means we diagnose and repair your Trane equipment based on what’s actually wrong with it, not what a manufacturer program tells us to sell. Our technicians work on Trane systems across San Antonio and the Hill Country year-round, from 14 SEER XR14 condensers to XV20i variable-speed heat pumps. If your Trane is acting up, call (361) 470-8872 and a live person answers, 24 hours a day.
The difference with us comes down to where Trane experience meets San Antonio conditions. We know what the city’s brutal, humid, multi-month heat does to a Trane condenser, and we know which failure patterns show up on which model lines. That matters when you need a real diagnosis, not a guess. Call us and you’ll get a written price before any work starts, every time.
Why Trust Brandt HVAC Co San Antonio for Your Trane HVAC?
Our techs work on Trane equipment daily across San Antonio and the Hill Country, from 14 SEER XR14 condensers to XV20i variable-speed heat pumps, and we stock or source the specific components these systems actually need. That independent, model-level experience means we diagnose Trane failures accurately without being tied to any manufacturer program. We’ve seen which Trane parts fail in this climate and which ones hold up, because we’ve changed enough of both to know the difference.
Devin Marlowe, our owner, learned the trade at Los Angeles Trade-Technical College and spent the better part of two decades working on HVAC systems across the Southwest before running service calls throughout San Antonio. He’s the kind of guy who remembers which customers have a dog that likes to supervise the repair, and he quotes every job straight: what needs fixing, what it costs, and what the warranty actually covers, no footnotes. That’s how every Brandt HVAC Co San Antonio technician works, too.
Every technician we send to your door is background-checked and identity-verified under our Threshold Verified standard. You get the technician’s name and photo before the visit, and they show a photo ID badge at the door. If anyone arrives who you weren’t told to expect, that visit is on us and we make it right. We know opening the door to a stranger is a genuine concern for a lot of San Antonio homeowners, especially people who are home alone or parents with young kids. Our process removes that uncertainty completely.

Common Trane HVAC Problems We Fix in San Antonio
Here are the Trane failures we see most often in San Antonio. These aren’t generic AC problems; they’re the ones tied to specific Trane model lines and the way this city’s climate stresses them.
- ComfortLink communication faults on XV18 and XV20i variable-speed units. After San Antonio thunderstorms, we get calls for Trane variable-speed outdoor units throwing communication faults. The fan motor control boards lose sync with the ComfortLink II thermostat and lock out the compressor. You’ll see error codes, or the unit just stops cooling. The fix is usually a board re-sync or replacement of the control board, not the compressor. We’ve done enough of these to diagnose them fast.
- R-410A TXV metering devices sticking closed on XR14 and XL16i evaporator coils. This shows up as low suction pressure, coil freeze-ups, and intermittent cooling during peak afternoon heat. The TXV sticks, the refrigerant flow chokes, and the system can’t pull heat. It’s a part replacement on the evaporator coil side. If you notice your Trane cools fine in the morning but struggles at 3 p.m., this is a real possibility.
- Trane gas furnace ignitors cracking on XT80 and XC80 models. Thermal cycling cracks these ignitors over time, and the first cold front of the season brings no-heat calls. The ignitor fails, the gas doesn’t light, and the furnace blows cold air. It’s a straightforward part swap, and we keep these ignitors stocked because we know the pattern.
- Condensate drain pan cracking on horizontal Trane air handlers installed in San Antonio attics. High-humidity summer weeks mean these pans fill constantly, and plastic pans degrade under attic heat. A cracked pan leaks water into your ceiling below the unit. We replace the pan and check the drain line while we’re at it.
- Pitted condenser fins from hail and oak pollen clogging coils every spring. In many northwest-side neighborhoods built since the 1990s, original 10-SEER condensers are still limping along after 20+ years. San Antonio hail pits the fins, and oak pollen coats the coils in spring. We clean coils and straighten or replace damaged fin sections to get airflow back where it belongs.
Trane Parts & Our Repair-vs-Replace Approach
For Trane systems under warranty, or when the failed component is safety- or communication-critical, we install genuine Trane OEM parts. That means boards, gas valves, variable-speed motors, and communication modules get factory components, because aftermarket parts often cause repeat failures on Trane’s proprietary controls. Trane’s ComfortLink system in particular doesn’t tolerate off-brand boards well. We’d rather put the right part in once than come back twice.
For out-of-warranty systems over 12 years old, or when you’ve got a leaking evaporator coil, we give you a straight cost-per-year-of-remaining-life comparison. Repair or replace is a financial question, not a sales pitch. If a new Trane XR14 or RunTru system makes more sense than putting $2,000 into a 14-year-old unit, we’ll tell you that plainly and show you the math. Call (361) 470-8872 with your model number and symptom, and we’ll talk through what’s realistic.
Our Trane Service Process – Step by Step
- 1
Diagnosis. Our technician arrives, introduces themselves with their photo ID badge, and runs a full diagnostic on your Trane unit. For XR14 and XL16i systems, that includes checking refrigerant pressures and TXV operation. For XV18 and XV20i variable-speed units, we pull the ComfortLink fault codes and check the communication path.
- 2
Written price. We hand you a written price for the repair before any work starts. No parts get ordered, no labor begins, until you’ve seen the number and agreed to it. That’s non-negotiable at Brandt HVAC Co San Antonio.
- 3
Repair or installation. We complete the work using OEM or contract-quality parts matched to your system. Furnace ignitor replacements on XT80 and XC80 models typically get done same day because we carry the parts.
- 4
Testing and verification. We run the system through full heating and cooling cycles, check temperature splits, and verify the fault codes are cleared. For variable-speed units, we confirm the ComfortLink thermostat reconnects cleanly.
- 5
Written warranty. Every repair includes a written guarantee that states exactly what’s covered and for how long. If the repair fails within the guarantee period, we return free of charge under our 365-Day Done Right Promise.

AfterTrane Products We Service & Install in San Antonio
We service and install Trane XR14, XL16i, and XV18 model lines, plus Trane service in Cibolo and across the region. That covers single-stage, two-stage, and variable-speed AC condensers and heat pumps, plus Trane gas furnaces and air handlers. We also work on older Trane systems from the 1990s and 2000s that are common in established San Antonio neighborhoods. Our local stock includes common Trane ignitors, capacitors, TXVs, contactors, and ComfortLink control boards, which keeps turnaround fast on the most frequent repairs.
A field example from our files: Our tech arrived at a Terrell Hills home on a 101° afternoon where a Trane XL16i heat pump was blowing warm air. The compressor was running but the outdoor fan was not. The condenser fan motor capacitor had failed and the motor was drawing locked-rotor amps. We replaced the capacitor with an OEM 45/5 MFD 440V unit and verified the motor windings with a megger before restart, restoring a 19° split and cooling the house in under an hour.
We Also Service These Brands
While Trane is a big part of our work, we also offer our AC Repair services for all major residential HVAC brands in San Antonio, including Carrier and Lennox. You don’t need a different company for each system in your house, and you don’t need to worry that we’ll recommend Trane because that’s all we know. We give you the same straight diagnosis regardless of the badge on the unit.
FAQs – Trane HVAC Service in San Antonio
Those ComfortLink fault codes indicate a communication failure between the outdoor unit’s control board and the indoor thermostat. San Antonio thunderstorms cause power fluctuations that knock the boards out of sync, which locks out the compressor until the system re-establishes communication. The fix is typically a board reset or replacement, not a compressor issue. Call (361) 470-8872 and we’ll walk you through what your specific code means before we even schedule the visit.
It could be low refrigerant, but on XR14 and XL16i systems in San Antonio we also see stuck R-410A TXV metering devices on the evaporator coil causing low suction pressure and coil freeze-ups. A pitted or pollen-clogged condenser coil will also reduce cooling capacity, especially in spring when oak pollen is heavy. The only way to know is with gauges and a proper coil inspection. We’ll give you a written price for the diagnosis before we start, so you know what you’re spending up front.
Every six to twelve months for a 4-inch or 5-inch media filter, depending on how many people live in the house, whether you have pets, and whether you’re running the system year-round. In San Antonio, where AC runtimes are extremely high from May through September, filters load up faster than the manufacturer’s generic recommendation suggests. A clogged filter on a Trane furnace or air handler drives up static pressure and shortens blower motor life. We’ll check the filter when we’re out for a tune-up and tell you exactly what yours looked like.
Short-cycling on an XC80 is most often a cracked ignitor that has a hairline fracture in the heating element. It’ll light, then the cracked section opens and the furnace shuts down, then tries again. Another possibility in San Antonio attics is a dirty flame sensor, which is a quick clean, or an overheating limit switch from restricted airflow. Cold mornings bring this on because the furnace runs harder and the thermal cycling is more severe. We’ll diagnose it and tell you the exact part before we replace anything.
At 14 years old, a leaking evaporator coil is usually the financial tipping point. A coil replacement on an out-of-warranty XR14 can run deep into four figures, and the remaining compressor life is uncertain. We’ll give you a straight cost-per-year-of-remaining-life comparison: what the repair costs divided by the years you can reasonably expect from the system, versus what a new Trane or RunTru system costs divided by 15 to 18 years. That’s the honest way to look at it, and Devin Marlowe will tell you plainly if we think repair is throwing good money after bad. Call (361) 470-8872 for the numbers on your specific unit.

No, we’re an independent Trane service provider. We’re not part of any Trane dealer or manufacturer program. That’s actually why our Trane diagnosis is so straightforward. We don’t have an authorization relationship that pushes us toward replacement over repair. We work on what’s in front of us, and we tell you what we find. If your system is under warranty, we’ll use genuine OEM parts so the warranty stays intact.
Yes, on safety- and communication-critical components like control boards, gas valves, and variable-speed motors, and on any system under warranty. Trane’s ComfortLink controls and variable-speed drives don’t respond well to aftermarket substitutions. For out-of-warranty systems on basic mechanical parts where aftermarket quality is equivalent, we’ll present the option and let you decide. Every choice is in writing before we start.
Most common repairs, like ignitor replacements, capacitor swaps, or TXV replacements, are done same day when we have the part stocked, which we usually do for the most frequent Trane failures in San Antonio. Variable-speed control board replacements may take a day or two if the board needs to be sourced. You’ll know the timeline before we start, along with the written price.
We service and install XR14, XL16i, and XV18 lines, plus RunTru by Trane, along with older Trane systems still running in San Antonio homes. That includes single-stage, two-stage, and variable-speed condensers, heat pumps, furnaces, and air handlers. If you’re not sure which model you have, call us and we’ll help you read the data plate.
No, as long as the work is done correctly with genuine Trane OEM parts where required. We’re an independent provider, which means we can service Trane equipment without affecting the manufacturer’s warranty, provided we follow proper procedures and use the right components. We document everything on the invoice, so if you need to file a warranty claim, you have the record.
A full Trane AC or heat pump installation in San Antonio typically runs $3,500 to $7,500, depending on model, efficiency tier, and whether we’re replacing inside and outside units together. That’s the installed price, not just equipment. We’ll give you a written fixed price before any installation starts, and we’ll handle the rebate and financing paperwork if that applies. Call (361) 470-8872 for a specific quote on your house.
