This page is for San Antonio homeowners who own a Goodman furnace and want straight answers: what breaks, why it breaks, what it costs, and whether a repair makes sense versus a replacement. We service every Goodman line you’re likely to have in your home, from the entry-level Goodman GMSS series to the higher-end GMVM modulating units. No brand is perfect, and Goodman has its own set of common failures we see across the city, from Stone Oak to Alamo Heights.

How Goodman Products Fail – and How We Fix Them

• Ignitor failure on the GMSS and GMS series (90% AFUE single-stage) – This is the number one Goodman call we run in San Antonio. The silicon nitride ignitors on these units get brittle after four to six years, especially with the start-stop cycling that comes with our milder winters. You’ll hear the furnace click on, the draft inducer runs, but no flame ever lights. One of our techs confirms the ignitor is cracked, and most replacements run $150 – $300 including the part and labor.
• Pressure switch tripping on the GCVM and GMVM modulating units – These higher-end Goodman lines use more sensitive pressure switches to verify draft before ignition. What we see in San Antonio is not usually a bad switch but a partially blocked condensate drain or a vent pipe with a dip that’s collected water. The fix is often clearing the obstruction, not replacing the switch. A tech who doesn’t know Goodmans will swap the switch, bill you, and leave the real problem in place. We test the full vent path before we call anything a failed part.
• Heat exchanger stress on 80% AFUE units (GME, GMS8) – Older single-stage Goodmans in San Antonio run hard on the few genuinely cold nights we get, and then sit idle for weeks. That uneven load stresses the heat exchanger seams. We look for hairline cracks during every repair visit, not just when we’re replacing a limit switch. If we find one, we’ll tell you plainly whether a repair makes sense or if the unit’s age pushes the math toward replacement. Heat exchanger repairs on a Goodman usually only make sense while the unit is still under the 20-year or lifetime heat exchanger warranty; after that, the labor cost rivals a new system.
• Gas valve sticking on the 90% line (GMSS96, GCVM96) – Goodman’s two-stage gas valves on the 96% AFUE units have a known tendency to stick on low fire after repeated cycles. You’ll get weak heat, a furnace that runs but doesn’t satisfy the thermostat. Sometimes a good cleaning solves it; sometimes the valve needs replacing, which runs $250 – $500 installed depending on the exact valve. Either way, we’ll show you the old part and explain what you’re paying for before we touch it.
• Blower motor and control board quirks on the GMEC96 and GME8 – These ECM-equipped Goodmans occasionally throw a “motor fault” code that’s actually the control board misreading the motor, or the other way around. We bench-test both before recommending anything. A blower motor replacement runs $400 – $700; a board alone is typically $250 – $450. Guessing wrong here doubles the bill, so we test first. Always.

One detail most Goodman owners don’t get from the factory website: many of the “failed part” codes on these furnaces are actually connection issues at the molex plugs. A pin backs out slightly, the board sees an open circuit, and the furnace locks out. That’s a $100 fix we catch on the first visit, not a $500 part replacement some other shops will sell you. – Enough. Let’s talk process.

Our Goodman Furnace Repair Process

1. 1
   You call, a live person answers. Around the clock. You’ll tell us the symptoms, the model number if you have it, and we’ll schedule a visit. No voicemail, no callback queue.
2. 2
   You know who’s coming. Before the technician arrives, we send their name and photo. At the door, they’ll show a photo ID badge. If the person standing there isn’t the person we said was coming, that visit is on us. That’s our answer to Threshold Verified, and we don’t bend on it.
3. 3
   Diagnosis with a written price. The tech opens the cabinet, pulls error codes, checks the ignitor, flame sensor, pressure switch path, and heat exchanger. Then you get a written price for the repair. No work starts until you’ve seen the number and said yes.
4. 4
   The repair, using proven parts. We use OEM Goodman parts when they’re available and priced fairly; we’ll offer a quality aftermarket option when it makes sense and tell you the difference before you decide. No mystery parts.
5. 5
   Full test cycle. We fire the furnace, watch it light, run a full cycle, check flue draft, check for gas odor, and make sure the blower runs clean. We don’t leave until the house is heating.
6. 6
   Written guarantee. Every repair gets a written guarantee. If that repair fails within the coverage period, we come back and fix it free under our 365-Day Done Right Promise. No argument, no second invoice.
