Wall and floor furnaces are common in older Bay Area homes — especially on the Peninsula and in East Bay cities like Alameda, San Leandro, and Hayward, where a lot of housing predates central ducted systems. These units are simpler than a central furnace, and their repairs tend to cost less too. Here's what we actually charge for the most common wall- and floor-furnace repairs, what changes the price, and what's included.
Wall and floor furnaces aren't quite the same thing, though people often use the terms interchangeably. A wall furnace is mounted in or recessed into an interior wall; a floor furnace sits below the floor, with a grille you can feel warm air rising through. Both are simpler, single-room-or-zone systems compared to a central ducted furnace, which is part of why their repairs cost less too.
What wall & floor furnace repair costs in the Bay Area
Across the Bay Area, wall and floor furnace repairs typically run $129–$600, parts and labor included, quoted flat before we start.
| Repair | Typical Cost |
|---|---|
| Thermocouple | $80–$280 |
| Pilot assembly | $100–$320 |
| Gas valve | $150–$450 |
| Blower (fan models) | $180–$500 |
We charge a diagnostic fee to confirm the exact fault before any part is ordered. It's credited toward the repair when you approve the work.
What drives the price
- Which part failed. A thermocouple is a small, inexpensive safety part and one of the least expensive fixes on this list; a gas valve controls fuel to the burner and costs more to replace.
- Pilot vs. electronic ignition. Many older wall and floor furnaces still use a standing pilot light and thermocouple; if the whole pilot assembly needs replacing rather than just the thermocouple, the job moves up to $100–$320.
- Fan (blower) models vs. gravity models. Older gravity wall furnaces have no blower motor at all — heat simply rises. Newer fan-assisted models add a blower motor, which is the highest-cost part on this list at $180–$500 when it fails.
- Age and parts availability. Many wall and floor furnaces in Bay Area homes are original to the house. Parts for older or discontinued models can take longer to source than parts for a current model.
- Access. Floor furnaces sit in the floor itself and wall furnaces are recessed into a wall cavity, so tight clearances can add labor time versus a furnace with an open service panel.
Repair or replace? As a rule of thumb, if the unit is under about 8 years old and the repair costs less than half of what a replacement would run, repairing it is usually the smart call. On an older, original-to-the-house unit, a gas valve failure is often where it's worth asking us for an honest repair-vs-replace recommendation rather than defaulting to either option.
What's included
Every wall or floor furnace repair call includes:
- A gas safety check and diagnostic to confirm the actual fault.
- A flat, upfront price before any part is ordered.
- Parts and labor for the repair itself, done to code.
- An honest repair-vs-replace read if the unit is old enough that sourcing parts is getting difficult.
- The diagnostic fee credited toward the repair once you approve the work.
DIY checks vs. calling a pro
If the pilot light is out, check your owner's manual (often on a label inside the furnace's front panel) for the relight procedure — many units have a simple push-button igniter. Make sure the gas is on at the shutoff valve, and clear anything blocking the furnace's front grille so air can circulate.
Gas valves, pilot assemblies, and anything involving a gas smell are not DIY territory. If the pilot won't stay lit after a proper relight attempt, if you smell gas, or if the unit is original to an older home and has never been serviced, it's time to call a licensed tech. If your furnace has an electronic igniter instead of a standing pilot, don't try to manually light it — a failed igniter is a repair call, not a workaround.

Frequently asked questions
How much does wall or floor furnace repair cost in the Bay Area? Most repairs run $129–$600 depending on the part. A thermocouple is about $80–$280, a pilot assembly $100–$320, a gas valve $150–$450, and a blower on fan-assisted models $180–$500.
Why is a thermocouple repair one of the cheaper fixes? A thermocouple is a small safety sensor that confirms the pilot flame is lit before it allows gas to flow — it's inexpensive to source and quick to replace, which keeps the repair near the low end at $80–$280.
Do all wall furnaces have a blower motor? No. Older gravity wall furnaces rely on heat rising naturally and have no blower. Newer fan-assisted models add a blower motor, which is the highest-cost part on this list at $180–$500 if it fails.
My pilot light keeps going out — is that the thermocouple or the pilot assembly? It could be either. A worn thermocouple is the more common and less expensive cause ($80–$280); if the whole pilot assembly needs replacing, it runs $100–$320. A tech can tell which one you need.
Is the diagnostic fee separate from the repair cost? We charge a diagnostic fee to confirm the fault, but it's credited toward the repair when you approve the work — so it's not an add-on cost.
Are wall and floor furnaces common in the Bay Area? Yes, especially in older Peninsula and East Bay homes — cities like Alameda, San Leandro, and Hayward have a lot of housing stock built before central ducted systems were standard.
