How Goodman Products Fail – and How We Fix Them

Goodman sells more furnaces in the U.S. than nearly any other brand, and they’ve built a reputation for affordable, straightforward equipment. That’s a good thing. The trade-off is that certain parts fail in predictable ways. Here’s what we see repeatedly in San Francisco homes:

• GMSS96 and GMES96 pressure switch lockouts. These 96% efficient models have a narrow tolerance for venting changes. In San Francisco, older homes with converted garages or previous flue work often trigger pressure switch errors. The furnace locks out, the board blinks a code, and the house stays cold. We test the switch and the vent path, then replace or re-route as needed rather than just swapping parts and hoping.
• GKS9 and GME8 ignitor failures. The silicon nitride ignitors on 80% Goodman models can crack after 7 to 10 years of San Francisco’s damp, salt-heavy coastal air. We see this most often in Sunset District and Richmond District homes where the winter air carries real moisture. We replace with OEM Goodman ignitors because the cheaper universal ones run too hot and burn out in two seasons.
• Goodman flame sensor carbon buildup. This isn’t really a parts failure, it’s a maintenance failure. The flame sensor gets coated in carbon, the furnace fires, then shuts down after 10 seconds. It mimics a gas valve problem. We clean the sensor, check the burners, and if the carbon returns fast, we look at gas pressure and air intake. We don’t sell a gas valve unless the gas valve is actually bad.
• GMVC96 modulating gas valve drift. The variable-speed, modulating Goodman units are great when they work. But the modulating gas valve can drift out of calibration, causing the furnace to fire at the wrong rate and overheat. On a GMVC96, that often trips the rollout switch. We test actual gas pressure against the control board’s target, not just what the spec sheet says it should be.
• Draft inducer motor noise on all Goodman 80% and 90% lines. The inducer bearings wear out, and you’ll hear a grinding drone before full failure. We catch these early on tune-ups. The replacement is straightforward, and we stock both OEM and a quality aftermarket option so you can choose based on budget and how long you plan to stay in the home.

Our Goodman Furnace Repair Process

Here’s how a Goodman repair works when you call Brandt HVAC Co San Francisco:

1. 1
   You call, a person answers. No phone tree, no voicemail. We ask what the furnace is doing, and Devin Marlowe’s crews use that to bring the right parts the first time. Tell us what it’s doing, and we’ll tell you exactly what it needs.
2. 2
   You meet your technician before the door opens. We send a name and photo before arrival. The tech shows a photo ID badge at the door. If anyone else shows up, that visit’s on us.
3. 3
   Diagnosis with plain-language explanation. We test the Goodman control board codes, gas pressure, ignitor, flame sensor, and limit switches. You’ll hear the real words and what they mean: “your pressure switch is reading an open vent because the intake is partially blocked” not “we need to run some diagnostics.”
4. 4
   Written price before work starts. Every part, every labor hour, every option: OEM or aftermarket, repair or replace. You decide. We don’t start until you’ve seen the number and agreed.
5. 5
   The repair and a real test. We fix it, then run the furnace through at least three full heat cycles. We check the gas pressure, flame pattern, and start-up sequence.
6. 6
   Guarantee in writing. Every Goodman repair gets a 365-Day Done Right Promise. If the repair fails within one year, we come back free. No argument, no additional charge.

What Goodman Furnace Repair Costs in San Francisco

Goodman repair pricing in San Francisco breaks down by the part and the labor to get to it. Most jobs fall in the $175 to $825 range, depending on what failed:

• Flame sensor cleaning or replacement: $175 – $260
• Ignitor replacement (OEM Goodman): $225 – $375
• Pressure switch replacement: $190 – $320
• Draft inducer motor replacement: $400 – $650
• Gas valve replacement: $450 – $825
• Heat exchanger repair (where possible): $600 – $825
• Full diagnostic visit (applied to repair): $95 – $235

What moves the price is part availability and access. A Goodman gas valve in a clean basement furnace takes an hour. The same valve in a packed utility closet in a Pacific Heights Victorian takes longer, and that’s reflected honestly in the written quote. You’ll know the exact number before we touch a screw.
