Overview
### The Most Common Gas Furnace Failures Gas furnaces fail in predictable ways. The most frequent call we receive is a furnace that won't ignite — almost always a failed hot surface ignitor ($150–$250 repair) or a dirty flame sensor. The second most common is a furnace that runs briefly and then shuts off — typically a failing pressure switch, a restricted flue, or an overheating condition triggering the high-limit switch. The third is a blower that runs but produces no heat — usually a gas valve or inducer motor issue.
### Safety First on Every Gas Furnace Call Every gas furnace service call begins with a safety check. We verify the flue is clear and draft is adequate, test the heat exchanger for cracks using CO measurement, confirm the rollout switch is functioning, and check gas pressure at the manifold. We won't leave a system running that has a safety concern — but we also won't use safety concerns as a pretext for unnecessary equipment sales.
### All Brands Serviced Throughout Los Angeles We repair Carrier, Lennox, Trane, Rheem, Goodman, Bryant, York, American Standard, and all other residential gas furnace brands — both 80% AFUE and 96%+ AFUE two-stage and variable-speed models. Call (323) 970-3113 for same-day service.

What customers say about gas furnace repair
Verified reviews from Los Angeles homeowners who used our gas furnace repair service.
“Furnace was making a loud banging noise every time it started. LC diagnosed delayed ignition from dirty burners. Cleaned and tuned the whole system, tested CO levels, explained everything clearly. No upsell, fair price.”
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
“Pilot light kept going out on our older furnace. LC came out, replaced the thermocouple, cleaned the burner assembly, and did a full safety check. Fast, affordable, and they showed me how to relight it safely in the future.”
