Rheem AC repair in San Antonio typically runs $150 – $650 depending on the part that failed, and most jobs are done the same day we diagnose them. We’re an independent Rheem service provider, which means we fix the system you have without steering you toward a replacement you don’t need. If your Rheem unit is blowing warm air, short-cycling, or making a sound it never made before, call (361) 470-8872 and a live person answers, day or night.

This page is written for Rheem owners in San Antonio who want to know what actually breaks on these units, what a fair repair costs, and who they’re letting into their home to fix it. Devin Marlowe runs our crew, and the standard he set is simple: tell you what’s wrong, what it costs in writing, and what the guarantee covers. No footnotes.
How Rheem Products Fail – and How We Fix Them
- Capacitor failure on Rheem Classic and Prestige series condensers. San Antonio heat cooks capacitors faster than almost anything else on the unit. The symptom is a condenser that hums but won’t start, or a fan that spins sluggishly after the system’s been running hard all afternoon. We test the capacitor under load, not just with a visual check, because a capacitor can look perfectly fine and still be 40% out of spec. Replacement runs $150 – $300 parts and labor, and we use USA-made capacitors rated for 105°F ambient and above.
- Contactor pitting and welding on Rheem RA14 and RA16 outdoor units. A contactor is the electrical switch that tells your compressor and fan to turn on. Over years of cycling in San Antonio’s dust and humidity, the contacts arc and pit until they weld shut or burn open. When they weld, the outdoor unit keeps running even after the thermostat satisfies, which is a fast way to ice the coil. We replace with a contactor rated above the unit’s rated load amperage, and we tighten every lug to torque spec as part of the job.
- Evaporator coil leaks on Rheem’s RCF series matched coils. This is the most expensive failure on this list and the one Rheem owners ask about most. The aluminum evaporator coils on RCF-series air handlers can develop pinhole leaks after 8 – 12 years, especially in coastal-adjacent Texas air that carries more salt and humidity than Rheem’s own test conditions account for. We diagnose with an electronic leak detector and confirm with nitrogen pressure test before we ever quote a replacement or a repair, because you deserve to know it’s actually the coil and not a Schrader valve. Repairs here range $400 – $850 depending on access and coil size, and we’ll tell you straight if replacement is the smarter money.
- Condenser fan motor bearing wear on Rheem’s single-stage outdoor units. You’ll hear this one before you see it: a grinding or squealing from the top of the outdoor unit that comes and goes. San Antonio’s fine caliche dust works its way past the motor’s sealed bearing over time, and once the bearing starts to drag, the motor pulls more amps and runs hotter until it quits entirely. We keep common Rheem fan motor sizes on our trucks and can usually have this repaired same-day, $250 – $450 installed.
- Thermostat drift and wiring failures on Rheem EcoNet systems. The EcoNet control platform is solid, but the low-voltage wiring between the thermostat and the air handler in San Antonio attics runs through some of the hottest enclosed spaces in any American home. Insulation gets brittle, wires chafe, and you get intermittent communication errors that look like a control board problem but aren’t. We ring out the low-voltage circuit before condemning any board, because replacing a $500 control board when a $40 wiring repair fixes it is exactly the kind of thing we won’t do to you.
Styles & brands we work with






Our Rheem AC Repair Process
- 1
You call, a person answers. We take your number, your address, and what the system is doing. You’ll get a text with the name and photo of the technician coming to your door before we arrive. If the person at your door doesn’t match that photo and show ID, that visit is on us.
- 2
We diagnose with tools, not guesses. Manifold gauges for refrigerant pressures, amp draws on the compressor and fan motor, capacitor test under load, and a temperature split across the coil. We find the actual failure before we talk price.
- 3
You get a written price before any work starts. No exceptions. The price includes parts, labor, and any refrigerant or materials needed. You approve it in writing or we don’t turn a screw.
- 4
Parts decision, stated plainly. If a genuine Rheem OEM part is available quickly and makes sense, we use it. If a quality aftermarket part matches or exceeds the OEM spec for less money, we tell you that too and let you choose. We never hide a parts source.
- 5
The repair, then the test. We don’t leave until the system runs a full cycle, hits its temperature split, and the compressor and fan amperages are in spec. You see the numbers before we pack up.
- 6
Your written guarantee, in hand. Every repair includes a written guarantee. If that repair fails inside the guarantee period, we come back and fix it at no charge under our 365-Day Done Right Promise. No argument, no invoice.

Why San Antonio Homeowners Call Brandt HVAC Co San Antonio for Rheem Work
Most companies can swap a part. What takes longer to build is the certainty that the person at your door is who we said they’d be, the price won’t move after you approve it, and the repair is covered by a written guarantee that actually means something. Every technician we send is background-checked and identity-verified under the Threshold Verified standard, introduced by name and photo before we arrive, and badged at your door.
Devin Marlowe’s crew has handled enough Rheem units across San Antonio, from Alamo Heights to Stone Oak to the neighborhoods near the Pearl District, to know which failures show up on which series and what a San Antonio summer does to a system that skipped maintenance. And while Rheem is a big part of our repair volume, we service every major residential brand including Carrier, Trane, and Lennox, so if your Rheem is paired with another brand’s coil or furnace, it’s not a problem. One call handles the whole system.

Frequently Asked Questions
No, we’re an independent Rheem service provider, not an authorized Rheem dealer. That means we’re not limited to one brand’s parts pipeline, and we’ll recommend whichever repair is actually best for your system and your budget. Our Rheem repair work doesn’t void any manufacturer warranty, because we diagnose the failure and document it before repairing.
In most cases, yes. If you call before mid-afternoon and the part our diagnostic identifies is one of the common Rheem components we keep stocked on our trucks, we can often complete the repair the same day. Call (361) 470-8872 and tell us what your system is doing, and we’ll give you an honest ETA.
We’ll use genuine Rheem OEM parts when they’re the right choice for availability and price. If a quality aftermarket part matches or exceeds the Rheem specification at a better price, we’ll tell you both options and let you decide. On warranty-relevant repairs inside the manufacturer’s coverage window, we use OEM parts to keep your warranty intact.
If the repair is a capacitor, contactor, fan motor, or thermostat, repair is almost always the smarter money, even at 12 years old. If you’re looking at a failed compressor or a leaking evaporator coil and your system uses R-410A refrigerant, replacement starts making more sense, because putting $850 into a 12-year-old system is buying time, not years. We’ll give you our straight answer on the job, and we won’t quote a replacement unless the numbers support it.
Every repair we do includes a written guarantee stating exactly what’s covered and for how long. If that repair fails inside the guarantee period, we return and fix it free of charge under the 365-Day Done Right Promise. You’ll want other companies to put their guarantee in writing once you see what ours actually says.
