Rheem furnace repair in San Antonio typically costs between $150 and $700, and most repair visits we schedule are completed the same day the technician arrives. We’re an independent Rheem service provider, which means we diagnose and fix Rheem furnaces without being tied to manufacturer warranty restrictions that sometimes delay repairs. If your Rheem is short-cycling, blowing cold air, or making a sound you’ve never heard before, call (254) 271-2545 and a live person will answer, day or night.
This page is for San Antonio homeowners who own a Rheem furnace and want to understand what’s wrong, what it should cost, and who they can trust to fix it without turning the living room into a worksite. Luis Serrano and our crew have run Rheem-specific diagnostics in homes from Alamo Heights to the Pearl District, and we’ve learned that Rheem failures follow patterns that are different from Carrier, Trane, or Lennox. That pattern recognition is what keeps your repair bill from becoming a parts-replacement guessing game.
How Rheem Products Fail – and How We Fix Them
- Classic 90 Plus and 80 Plus induced-draft pressure switch trips. These Rheem mid-efficiency lines use an induced draft motor that pulls combustion gases through the heat exchanger. In San Antonio, the real culprit is often a partially clogged condensate drain or a small crack in the rubber pressure switch hose that only leaks under certain temperatures. We test the switch with a manometer before replacing it, because a $25 hose fixes what a $180 part swap guesses at.
- Rheem Classic Series hot surface ignitor failure. Rheem’s older 80% AFUE Classic Series units used a silicon nitride ignitor that gets brittle with age. The symptom is usually a furnace that tries to light, clicks, and then shuts down with no flame. We keep OEM Rheem ignitors in the truck as well as a quality aftermarket equivalent, and we’ll tell you the price difference before either one goes in.
- Rheem Prestige Series modulating gas valve codes. The Prestige line is a modulating furnace, and its gas valve is a sophisticated part. When it starts throwing error codes like “pressure switch stuck open” or “flame lost during run,” the fault is often a voltage drop at the control board, not the valve itself. We measure actual gas pressure at the manifold and verify board output before recommending a $400+ gas valve replacement.
- Induced draft motor bearing whine on R96V and R97V units. These high-efficiency Rheem units use a variable-speed draft inducer. A high-pitched whine that changes with furnace load is almost always motor bearing degradation. We don’t mask this with lubricant. We replace the inducer assembly with an OEM part when the unit is under warranty or a properly-matched aftermarket part when it isn’t.
- Heat exchanger corrosion in San Antonio’s humid shoulder seasons. Our climate means furnaces sit idle for long stretches, then run hard on the first cold snap. Moisture collects inside the secondary heat exchanger on 90%+ Rheem units, accelerating corrosion. We scope the exchanger with a camera when a homeowner reports a musty smell at startup or when a carbon monoxide detector tripped. A cracked heat exchanger is a safety issue, and we will say so plainly.

Our Rheem Furnace Repair Process
- 1
Call and talk to a person. You call (254) 271-2545. A live person answers. We ask about the symptoms, the Rheem model number, and when the problem started.
- 2
Written price before anything starts. The technician arrives in a marked truck, puts on shoe covers, and lays down a drop cloth before the front door closes. They diagnose the furnace, then hand you a written price for the repair. No work starts until you approve it.
- 3
The repair, done right. We use OEM Rheem parts when warranty or performance demands it, and quality aftermarket parts when they match or exceed original spec at a better price. Luis Serrano’s rule: never install a part we wouldn’t put in our own home.
- 4
Test, test, test. We cycle the furnace through startup, run, and shutdown. We check gas pressure, exhaust flow, and temperature rise across the heat exchanger. The furnace doesn’t get signed off until it runs a full cycle without a single anomaly.
- 5
Cleanup with a photo. Floors are swept, tools removed, and a photo of the clean work area is taken before we leave. You’ll see exactly what the space looked like when we walked out.
- 6
The 365-Day Done Right Promise. If the same problem comes back within a year, we make it right at no charge. No runarounds, no fine print.

That means shoe covers and drop cloths on every visit, a written price before any work starts, and a photo of the clean-up before we leave. Our technicians are background-checked, uniformed, and trained in the C.A.R.E. values: Clean up like it’s their own home, Ask before moving anything, Respect the family’s time and quiet hours, and Explain the price before the work.
We service Rheem furnaces every week, which means our techs know the difference between a 90 Plus pressure switch and a Prestige gas valve without staring at the wiring diagram for half an hour. And if your Rheem is beyond saving, we also service Carrier, Trane, and Lennox equipment, so we can talk honestly about whether repair or replacement is the smarter move for your home.
FAQs
Yes, in most cases we can dispatch a technician the same day you call, and the repair is usually completed during that first visit. Common parts like ignitors, pressure switches, and flame sensors are stocked on our trucks. If your specific Rheem part needs to be ordered, we’ll tell you honestly and give you a timeline before you spend anything.
No. As an independent Rheem service provider, we can perform repairs and routine maintenance without voiding your manufacturer warranty. What voids warranties is improper installation or using incompatible aftermarket parts. We check the warranty status on your specific serial number before recommending OEM versus aftermarket components, and we document everything so your warranty claim, if one exists, is supportable.
Common Rheem parts like ignitors, flame sensors, and pressure switches are available same-day from local supply houses, which is why most repairs are completed in one visit. Less common parts, like a Prestige Series modulating gas valve or a variable-speed inducer motor, typically arrive in one to three business days. We’ll always tell you the expected wait before you approve the work.
If your Rheem furnace is under 12 years old and the repair costs less than $500, repair is usually the right call. If the unit is 15 years or older and facing a $600+ repair like a heat exchanger or gas valve replacement, we’ll show you the numbers for a new system and let you decide without pressure. San Antonio winters are short but cold snaps are real, and an aging furnace failing in January is a problem you don’t want twice. Call (254) 271-2545 and we’ll assess your unit honestly.
Yes. A Rheem furnace tune-up runs between $80 and $200 depending on system age and whether it’s a mid or high-efficiency unit. We inspect the heat exchanger, clean the flame sensor, check gas pressure, and test the safety switches. A maintained Rheem furnace is less likely to fail on the first cold night, and maintenance also keeps your warranty valid. We’ll give you a written report of what we found, whether you need anything or not.
