What to expect from LC Heating & Air
### Annual Furnace Maintenance in Los Angeles Los Angeles winters are mild but real — temperatures in the San Fernando Valley and foothill communities regularly drop into the low 40s at night from November through February. A furnace that hasn't been serviced in over a year can fail on the first cold night when you need it. LC Heating & Air performs annual furnace maintenance throughout Greater Los Angeles to keep heating systems safe, efficient, and ready. View our recommended Heat Strip →
Overview
### Safety First: Carbon Monoxide and Heat Exchanger Inspection Furnace maintenance is a safety-first service. We test the heat exchanger for cracks using CO combustion analysis — a cracked heat exchanger is a carbon monoxide risk that is invisible without proper instruments. We also inspect and clean the burner assembly, test the hot surface ignitor, clean the flame sensor, check flue draft, measure temperature rise, and test all safety controls including the high-limit switch and rollout switch.
### When to Schedule Furnace Maintenance in LA Fall is the right time — September through November, before the first cold spell. Don't wait until December when we're already responding to heating failures. A fall tune-up finds problems when you have time to address them before they become emergencies on a cold night.
### CO Detectors Are Required in California California law requires CO detectors in all homes with gas appliances. If your home doesn't have CO detectors on every floor, install them. If your furnace hasn't had a professional safety inspection in over two years, schedule one. Carbon monoxide is colorless and odorless — annual professional inspection is your best protection.

What customers say about furnace maintenance
Verified reviews from Los Angeles homeowners who used our furnace maintenance 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.”
“Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.”
