Furnace Repair — questions answered.
How much does furnace repair cost in Campbell?＋
Most furnace repairs in Campbell range from $189 (diagnostic only) to $950. Flame sensor cleanings run ~$220, ignitor replacements $295, gas valves $550+, inducer motors $650+. Every quote is written and flat-rate.
Is it safe to keep running my furnace?＋
If your CO detector is going off, shut off the gas at the valve behind the unit and open windows. Call us immediately at (408) 797-9855. If there's an active gas smell, call PG&E 1-800-743-5000 first, then call us.
Can you repair my furnace today?＋
Same-day availability Mon–Sat. Call (408) 797-9855 for a hard 2-hour arrival window.
When should I replace instead of repair?＋
If you have a cracked heat exchanger, replace — never repair. Otherwise, 15+ year old furnaces with repair bills approaching $1,000 usually make more sense to replace, especially with SVCE rebates available for heat-pump conversions.
Do you service 90%+ AFUE condensing furnaces?＋
Yes — condensing, two-stage, modulating, and variable-speed. Every major brand.
