Furnace calls in Cerritos don't wait for business hours. Ignitors, flame sensors, and gas valves live on our truck — combustion analysis happens on every call with a calibrated CO meter, not guesswork.
Cerritos is home to roughly 50,555 residents across CA. We serve East Cerritos, Cerritos Town Center, and ABC Unified, plus surrounding neighborhoods for furnace repair. California Title 24 requires Home Energy Rating System (HERS) testing on qualifying AC installs — we handle the paperwork. Ask about current rebate programs from Southern California Edison (SCE), SoCalGas that can offset qualifying furnace repair work.
Calibrated CO meter on every visit. Check draft pressure, flame rectification, inducer RPM, gas pressure — before we touch anything mechanical.
Ignitors, flame sensors, pressure switches, inducers — on every truck. Most diagnostic-to-repair cycles close in one visit.
We run three full heat cycles + CO verification + thermostat satisfaction test before we leave. You see the readings.
Flame sensor fouling (80% of calls), failed ignitor, or gas valve lockout. We clean + test sensor output with meter first.
Dirty flame sensor, restricted return airflow, or failing pressure switch. We verify all three on the first visit.
Thermocouple failure or pilot orifice blockage. On 20+ year-old units, we also walk through replacement pricing.
Dust burn-off (normal first use of season), gas leak (emergency), or overheated wiring (fire risk). We test gas pressure + sniff for mercaptan.
Sequencer failure on electric furnaces, gas valve issue on gas, or failed igniter/flame sensor. All diagnosed with multimeter readings.
“Quoted 3× higher by a chain for furnace repair. This team explained everything, did the work right, backed it with a real labor warranty.”
“Furnace Repair tech was experienced — walked us through the diagnostic, showed the actual readings, fixed it on the first trip. That's how it should be done.”
“Called three companies for furnace repair; this one actually answered on a Saturday in Cerritos. Arrived with the right tools, finished the job, cleaned up.”
The usual causes: dirty flame sensor, failing pressure switch, restricted return airflow, or oversized equipment. We verify all four on the first diagnostic visit.
Same-day service for emergencies (no heat, gas smell). Routine service typically within 48 hours.
Yes — every furnace call gets a calibrated CO meter test. If we find unsafe levels, we red-tag the unit, inform the gas utility, and won't put it back in service until it's fixed.
If your system is over 10–15 years old, needs frequent repairs, or your energy bills keep rising, replacement may be more cost-effective than continuing to repair. {company} provides free estimates and can help you choose the most efficient system for your Cerritos home.
Average home leaks 20-30% of airflow through duct joints — confirmed by a Duct Blaster test. {company}'s $189 duct-leak diagnostic tells you exactly how much cooled/heated air you're losing to the attic before you invest in a new system.
If the builder provided a 2-year warranty and the contractor honors it — yes. After that, compare. Builder-grade equipment tends to be entry-tier; {company} can diagnose and service any brand, and recommend upgrades when they actually pay back.
