When your air conditioner stops cooling in San Antonio, the problem usually comes down to a handful of common failures: a blown capacitor, low refrigerant, a seized condenser fan motor, or a clogged drain line that tripped the float switch. Halden Heating and Air San Antonio fixes these issues daily, and we’ve been doing it since 2004. Every repair call includes a written price before any work begins and a written guarantee on the completed repair. If the same problem comes back within the coverage window, the second visit is free. Andre Fuller and our team of background-checked, uniformed technicians reach most San Antonio homes the same day you call, with a live arrival time you can track to the door. Call (903) 623-6784 for service.
AC Maintenance
AC Maintenance is the scheduled tune-up that keeps your system from failing in the first place, and our AC Repair Maintenance Checklist for San Antonio Homeowners covers what we inspect. In San Antonio’s climate, where your condenser sits in 100-degree heat for months at a time, a maintenance visit catches worn contactors, weak capacitors, and dirty condenser coils before they become a midnight breakdown. Halden Heating and Air San Antonio offers tune-ups that run between $80 and $200 depending on system size and condition, and every visit ends with a written report of what we found. The most valuable part is the measurement: we check refrigerant pressures, amp draws on the compressor and fan motor, and the temperature split across the evaporator coil, so you know exactly how hard your unit is working.
Coil Cleaning and Airflow Checks
A condenser coil caked with cottonwood, dust, and grass clippings can raise your electric bill by 20% or more while shortening compressor life. We clean the outdoor coil, check the blower wheel and filter, and measure static pressure to confirm the system can breathe. Most San Antonio homes in areas like Leon Valley and Helotes need this service twice a year because of our long cooling season, and we also provide AC Repair in Universal City for homes just northeast of the city.
Electrical Inspection and Capacitor Testing
We test the capacitor’s microfarad rating under load, inspect contactors for pitting, and tighten every electrical connection. A capacitor that’s drifted 10% below its rating will still start the compressor, but it’s pulling extra amps and generating heat. Catching that during maintenance costs a fraction of an emergency AC capacitor replacement at 2 a.m.
Styles & brands we work with
AC Service
AC Service covers the full range of repair, diagnostic, and corrective work needed when your system underperforms or stops entirely. In San Antonio, most service calls fall between $150 and $650, with the final number depending on the part that failed and the system type. Halden Heating and Air San Antonio approaches every service call the same way: a full diagnostic first, then a written price before anyone touches a tool. There’s no hourly meter running while we figure out what’s wrong, and no surprise at the door. Our AC Repair in San Antonio page explains the most common failures we see across town.
Troubleshooting Calls That Don’t Need Parts
Not every service call ends in a replacement part. Condensate drain clogs, tripped breakers, dirty filters, and thermostat misconfigurations account for a meaningful share of visits, and those jobs sit at the low end of the $150-$650 range. We’ll show you what we found, in plain English, and hand you a written summary before we leave.
System-Wide Diagnostic Service
When a unit has multiple issues or the problem isn’t obvious, we run a system-level diagnostic: refrigerant pressures, superheat and subcooling, compressor amp draw, fan RPM, temperature drop, and electrical supply voltage. That’s the difference between replacing a part that failed and replacing a part that was only a symptom. Our techs are certified on Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard equipment.
AC Unit Repair
AC Unit Repair means fixing the physical equipment itself, not just topping off refrigerant or clearing a drain line. In San Antonio, the most common AC unit repairs are condenser fan motors, blower motors, compressors, contactors, and control boards, with most jobs landing between $150 and $650 in parts and labor. Halden Heating and Air San Antonio carries common OEM and OEM-equivalent parts on our trucks, so a single-visit repair is the norm, not the exception. If we need to order a part, we’ll show you the expected arrival date and schedule the return visit before we leave your driveway.
Condenser and Blower Motor Replacement
A motor that hums but won’t spin, or spins slow and hot, is on borrowed time. San Antonio’s heat eats fan motors, especially on rooftops and west-facing condenser pads in neighborhoods like Timberwood Park and Fair Oaks Ranch. We replace the motor and run capacitor together as a set in most cases, because a failing motor almost always takes the capacitor down with it.
Compressor and Refrigerant Circuit Repairs
A failed compressor is the most expensive single repair on any AC unit, and it’s the one time we’ll walk you through the repair-versus-replace math honestly. We check the cause of failure before quoting a replacement, because installing a new compressor on a system with a leaky evaporator coil just burns the new part. You’ll get both options in writing with real numbers.
AC Capacitor Replacement
AC Capacitor Replacement is one of the most common repairs we perform in San Antonio. The capacitor is the electrical component that gives the compressor and fan motor the starting jolt they need, and in triple-digit heat it’s often the first part to fail. A typical AC capacitor replacement in San Antonio runs $150 to $350, including the part, and most jobs are finished in under an hour. Halden Heating and Air San Antonio tests capacitors on every maintenance and service visit, and when we replace one, we replace it with a properly rated part, not whatever happens to be on the truck.
Signs of a Failing Capacitor
A capacitor that’s starting to go often announces itself: the outdoor unit hums but doesn’t start, the fan is slow to spin, or the compressor short-cycles on and off. In Helotes and Scenic Oaks, where power quality can fluctuate during storm season, we see capacitor failures cluster after lightning-adjacent surges. If you hear that hum, shut the system down at the thermostat and call us rather than letting it continue to trip the breaker.
Dual-Run vs. Single-Run Capacitors
Many San Antonio homes have a dual-run capacitor that serves both the compressor and the fan motor. We test both legs independently, and if one side has drifted out of spec, we replace the whole component. A dual-run capacitor can fail on one side while still starting the other, which is why a system can blow warm air even though the fan is spinning.
AC Recharge
AC Recharge, also called a refrigerant top-off, restores the coolant level your system needs to produce cold air. In San Antonio, a recharge alone typically runs $200 to $450, but the real issue is why the refrigerant got low in the first place: systems don’t consume refrigerant like gas in a car. Halden Heating and Air San Antonio won’t just add refrigerant and leave. We leak-test the system with an electronic sniffer and nitrogen pressure test, and we’ll show you what we found before we quote any repair.
Refrigerant Types: R-22 vs. R-410A
If your system was installed before roughly 2010, it may run on R-22, which has been phased out of production and now costs far more per pound than its replacement, R-410A. Our techs carry both on the truck to keep most recharge calls to a single visit. We’ll tell you which refrigerant your unit takes and what the per-pound cost means for your repair estimate, with no jargon and no surprise line items.
Why Low Refrigerant Is a Symptom, Not a Diagnosis
A system that’s low on refrigerant has a leak somewhere, period. In areas like Castle Hills and Alamo Heights, we often find slow leaks at the evaporator coil or at brazed joints that have been vibrating for a decade. Adding refrigerant without finding the leak is the cheapest fix that costs the most over time, because you’ll be back in a month with the same problem. We’d rather find the leak once and fix it right, which is the same standard we hold on every AC Repair in San Antonio call.
Emergency AC Repair
Emergency AC Repair in San Antonio means a system that’s completely down during dangerous heat, and Halden Heating and Air San Antonio takes those calls seriously. Our phones are answered by a live person 24/7, not a voicemail tree, and we dispatch technicians on an emergency basis for same-day or after-hours service. Emergency AC repair pricing falls within our standard $150 to $650 range for most failures, and we do not charge overtime simply because it’s hot outside or late at night. Every emergency repair still includes a written price before work starts and a written guarantee on the result.
When Emergency Service Is Justified
A system that’s blowing warm air at 9 p.m. on a 102-degree day, a burning smell, or a compressor that won’t start are all legitimate emergency calls, especially in households with infants, elderly family members, or medical equipment. San Antonio’s late-summer stretch from mid-July through early September is when we run the most emergency calls across neighborhoods like Terrell Hills, Kirby, and Lackland AFB. If you’re not sure whether it’s an emergency, call us anyway; we’ll help you triage it over the phone at no charge.
What to Expect During an Emergency Visit
You’ll get a live arrival time and the technician’s name before we head your way. When we arrive, we diagnose the issue, show you the written price, and if you approve, we fix it on the spot. Most emergency repairs are completed in 60 to 90 minutes because our trucks are stocked with high-failure parts, including capacitors, contactors, fan motors, and common control boards for Rheem, York, Daikin, and Bryant systems.
AC Not Blowing Cold Air
AC Not Blowing Cold Air is the single most common complaint we get in San Antonio from June through September. The cause is usually one of five things: a failed capacitor, a refrigerant leak, a clogged or frozen evaporator coil, a faulty blower motor, or a thermostat that’s lost its cool. Halden Heating and Air San Antonio handles these calls daily, and most repairs fall between $150 and $650 depending on which part failed. The first thing we do is put a temperature probe on the supply and return vents to measure your actual temperature drop, so we know whether the system is underperforming slightly or not cooling at all.
Frozen Coils and Airflow Restrictions
An evaporator coil that’s frozen into a block of ice isn’t cooling anything, and it’s almost always caused by restricted airflow or low refrigerant. A dirty filter, collapsed duct, or closed vents can all cause the coil to freeze, and running the system while it’s frozen can slug the compressor with liquid refrigerant and destroy it. If you see ice on the copper lines or frost on the indoor unit, turn the system off at the thermostat and call us rather than letting it thaw and refreeze. Our team serves homeowners throughout the broader San Antonio area, including our neighbors we help on the AC Repair in Universal City page.
Compressor Runs but Air Is Warm
If the outdoor unit is running but the air coming from your vents is warm, the system has lost its ability to transfer heat, which almost always points to a refrigerant issue or a failing compressor. We check the compressor’s amp draw, the refrigerant pressures, and the temperature of the suction and liquid lines in the first ten minutes of the diagnostic. That gives us a clear picture of whether the problem is mechanical, electrical, or refrigerant-related, and you get the written price for the fix right after.
Brands We Service
Halden Heating and Air San Antonio technicians are factory-trained and certified to service major equipment brands, including Rheem, York, Daikin, and Bryant, along with Carrier, Trane, Lennox, Goodman, and American Standard. We have experience with Rheem’s classic cube-style condensers common in San Antonio’s older subdivisions, and we know their dual-run capacitor and contactor failure patterns well. York systems built in the early 2010s have a particular control board failure mode we diagnose quickly, which saves you time and diagnostic labor.
Daikin and Bryant units are increasingly common in new construction across Alamo Heights, Fair Oaks Ranch, and the I-10 corridor, and we carry OEM and OEM-equivalent parts for both on our service trucks. Whether you have a Rheem heat pump in Timberwood Park, a York unit in Helotes, or a Daikin system in Leon Valley, we can diagnose and repair it. And if your unit is another make entirely, the same written price, same written guarantee, and same free second visit apply.

- Your outdoor unit hums but won’t start. That hum is almost always a failed capacitor or seized fan motor, and continuing to let it sit and try to start will trip the breaker and can overheat the compressor. Shut the system down at the thermostat and call us before you try to spin the fan by hand; compressors damaged this way are the most expensive AC unit repair on the menu.
- Warm air is blowing instead of cold. A system that’s blowing warm air could be low on refrigerant, running without its compressor, or frozen solid at the evaporator coil. The longer it runs in this state, the more stress you’re putting on every component downstream, and in a San Antonio afternoon that heat gain in your house compounds fast.
- You see ice forming on the copper lines or the indoor unit. Ice on the refrigerant lines means the evaporator coil is freezing, and that’s a symptom of low refrigerant or blocked airflow. Running the system while frozen risks slugging the compressor with liquid refrigerant, which is a total system failure waiting to happen.
- The breaker for your AC keeps tripping. A breaker that trips once is a fluke; a breaker that trips twice is a system telling you something. The most common culprits are a failing compressor drawing excessive amps, a shorted fan motor, or a capacitor that’s failed closed. We see this pattern constantly in neighborhoods like Castle Hills and Terrell Hills during our longest heat waves.
- You smell burning or electrical odors from the vents or outdoor unit. A hot, acrid smell from the outdoor unit often means a failed motor or electrical component is overheating, while a smell from the vents can signal blower motor issues or a burned control board. Turn the system off at the thermostat immediately and call our 24/7 line at (903) 623-6784; we’ll walk you through what to do while a technician heads your way.
Our Process, Step by Step
We built our process around the thing San Antonio homeowners hate most about HVAC calls: the four-hour window and the price surprise. Here’s how every Halden Heating and Air San Antonio repair goes.
- 1
Call or book online. When you call (903) 623-6784, a real person answers, day or night. We take your address, the symptoms you’re seeing, and your preferred time, and we schedule a technician with a live arrival time you can track on your phone.
- 2
Your technician arrives, introduces themselves, and listens. Before any tool comes out, the tech gets your description of the problem. What temperature is the thermostat set to? When did it start? Which rooms are warmest? That context saves diagnostic time and points us to the right system fast.
- 3
Full diagnostic with measured findings. We test the capacitor under load, check amp draws, measure refrigerant pressures and superheat/subcooling if it’s a sealed-system issue, and confirm airflow and temperature drop. Everything is written down, and we’ll show you the numbers in plain English with specific readings from your unit.
- 4
Written price, approved by you, before any repair begins. We hand you a fixed price for the repair based on what we found, not an hourly estimate that can balloon. If there’s a less expensive temporary fix and a more expensive permanent one, you’ll see both clearly. No tool gets picked up for repair work until you approve the number.
- 5
The repair, the test, and the written guarantee. We make the repair, run the system through a complete cycle to confirm it’s cooling properly, and document before-and-after readings. You get a written guarantee on the repair, backed by our 365-Day Done Right Promise, which includes a free second visit if the same issue comes back within the coverage window.
How Much Does AC Repair Cost in San Antonio?
Most AC Repairs in San Antonio cost between $150 and $650, with the majority of straightforward jobs (capacitors, contactors, drain line clearing, thermostat replacement) falling in the $150 to $350 range. See how much AC Repair costs for a full breakdown. Refrigerant recharges typically land between $200 and $450 depending on the refrigerant type and the amount needed, while bigger jobs like a condenser fan motor or blower motor replacement usually run $350 to $650. A full compressor replacement is the exception, often exceeding the top of this range, and that’s when we’ll walk you through the repair-versus-replace decision with real numbers for both.
Three main factors drive the price: the part that failed, the refrigerant type if it’s a sealed-system issue, and the age of your equipment. R-22 systems cost more to recharge than R-410A systems because R-22 is no longer produced in the U.S. and what’s left is expensive. To avoid overpaying, get a written price before work starts and ask for the specific part number and test results that justify the repair. Our free estimates include the full diagnostic, the measured findings, and the written price, so you’ll never be asked to approve work blind.

Frequently Asked Questions About AC Repair in San Antonio
AC Repair is the process of diagnosing and fixing a malfunctioning air conditioning system so it cools your home properly again. It covers everything from replacing a failed capacitor or contactor to repairing refrigerant leaks, blower motors, and control boards. At Halden Heating and Air San Antonio, every repair starts with a full diagnostic and ends with a written guarantee, because a repair that isn’t proven to work isn’t a repair at all.
Most AC repairs take 60 to 90 minutes once the technician arrives, assuming the part is on the truck. Our service vehicles carry the highest-failure parts for Rheem, York, Daikin, Bryant, and other major brands specifically to keep most calls to a single visit. If a part has to be ordered, we’ll show you the expected arrival date and schedule the return visit before we leave, and the diagnostic findings stay on file so the return visit starts where we left off.
Most AC repairs in San Antonio cost between $150 and $650, with common jobs like capacitor replacement landing on the lower end and bigger repairs like blower motor replacement on the higher end. You’ll never get a phone estimate and a different number at the door; the price we quote after diagnosis is the price you pay. Call (903) 623-6784 for an exact quote on your system, because the diagnostic findings are always yours to keep whether or not you approve the repair.
