Furnace & Heating Repair services in San Jose
There's a reason furnace & heating repair in San Jose is mostly handled by small shops, not the big franchises: nobody beats a guy who knows the housing stock and answers his phone. Our pricing's flat-rate, our techs are state-licensed, and our trucks have parts on them. Most jobs done the same visit.
What's specific about San Jose jobs
Newer San Jose construction tends to be on slab foundations with PEX. Easier access in some ways, more code-current in others.
On bigger jobs we'll bring two techs. On simpler ones, just one — fewer hands, faster billing.
From the books — a recent San Jose job
Last spring we got a call from a homeowner near the south side San Jose. Heat pump blowing cold air in 28°f weather. Diagnosis: failed reversing valve solenoid. We replaced solenoid coil, recommissioned, ran the test, and were out the door in the same visit. Total: $675 including parts.
What we cover
Heating-side repairs run different than AC. Most furnace calls come down to ignitor failure, flame sensor, control board, or pressure switch. Heat pumps add reversing valve and defrost board.
Gas furnace ignitor failures are the most common winter call — about 40% of no-heat calls. The ignitor is a $35 part and a 20-minute job; total flat-rate runs $185-$340.
Heat pump no-heat in cold weather usually means failed reversing valve solenoid (system stuck in cool mode) or failed defrost board (outdoor coil iced up). Both diagnoseable in under an hour.
Older furnaces (15+ years) develop heat exchanger cracks. We check for them every diagnostic visit because a cracked heat exchanger leaks carbon monoxide and is a replacement-not-repair issue.
