Fresno furnace & heating repair
About a third of furnace & heating repair calls in Fresno turn out to be something the homeowner could fix in 10 minutes with a $12 part. We'll tell you which third. What we won't do: try to sell you a service plan, push the most expensive option, or send a sales rep before sending a tech.
Sample job
Last spring we got a call from a homeowner near the historic core Fresno. 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 in one trip. Total: $340 including parts.
What this service includes
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.
Notes on Fresno housing stock
Most weeks we run 12–18 calls inside Fresno alone. Different houses, similar fixes — we've seen yours before.
On bigger jobs we'll bring two techs. On simpler ones, just one — fewer hands, faster billing.
