When a furnace won't light, keeps shutting off, or the limit switch keeps tripping, resetting it doesn't fix the cause. Every Furnace Repair visit includes a carbon monoxide safety check before we leave, not an upsell.
A short list of components causes the overwhelming majority of Furnace Repair calls: the ignitor, the flame sensor, the gas valve, or the heat exchanger. Each gets tested with real equipment — multimeter, microamp readings, combustion analysis — instead of parts-cannon guessing.
What doesn't change from visit to visit.
Every furnace repair includes a combustion analyzer reading to check for dangerous CO levels, not an optional add-on.
No-heat calls during cold snaps get priority routing over routine maintenance stops when temperatures drop, especially in peak winter.
You approve a fixed repair price before any part is replaced, whether it's an ignitor or a heat exchanger.
Our techs are equally trained on gas furnaces and electric resistance systems, so the fuel type never determines who gets sent.
The most common furnace failure points.
A cracked hot-surface ignitor or a flame sensor coated in carbon buildup are two of the most common no-heat causes, and both are usually same-visit fixes.
Gas valve testing means checking actual response and pressure output, since these parts are costly enough to warrant confirming the fault first.
A cracked heat exchanger is a genuine safety issue that can leak combustion gases into the airflow — we inspect with a camera and combustion analyzer rather than assuming based on age alone.
Short-cycling or mid-cycle shutdowns frequently trace back to the limit switch or a struggling blower motor — we test both before condemning the control board.
Older furnaces with standing pilots have their own failure points — thermocouples, pilot orifices, draft issues — that we're equipped to handle that newer ignition systems don't have.
A furnace that won't respond at all to the thermostat is sometimes a wiring or control issue, not a furnace failure — we rule this out early to avoid overcharging for parts you don't need.
Four steps, safety checked at every one.
Describe the symptom — no heat, short-cycling, a smell — and we schedule the nearest available tech.
A stocked truck arrives in your confirmed window ready to diagnose and often repair on the spot.
Combustion analysis and component testing happen before any repair is quoted, then present a flat-rate quote for your approval.
Most furnace repairs are completed same-visit, with a final CO safety check before the tech leaves, backed by our labor warranty.
Feedback from completed furnace repairs.
Furnace kept shutting off every twenty minutes. The tech found a dirty flame sensor and cleaned it, been running fine for two months now.

They caught a hairline crack in the heat exchanger during a routine repair call and walked me through the safety concern honestly, not to upsell.
— V. Ashworth, homeowner
No heat during the coldest week of the year, they got someone out same day and had it fixed within an hour, ignitor replacement.
— Q. Delrio, homeowner
Old standing pilot furnace that most companies don't want to touch anymore. They knew exactly what they were doing, thermocouple was the issue.

Common questions before a Furnace Repair visit.
A furnace that clicks or hums but never lights is a strong sign of an ignitor issue, but we confirm with a resistance test before quoting.
Yes — it can allow combustion gases to mix with breathing air, which is why we test carefully and won't run the furnace if confirmed cracked, so we take the inspection seriously and won't operate a confirmed-cracked unit.
Yes, a combustion analyzer reading is part of every Furnace Repair service, included in the visit, no extra charge.
Yes — our techs are trained on thermocouples, pilot orifices, and draft diagnostics for older systems, including thermocouple and draft-related repairs.
We prioritize no-heat situations, usually landing a same-day slot even during high-demand cold weather.
Most common parts — ignitors, flame sensors, control boards — are stocked, but rare parts may need next-day ordering to complete the repair.
We dispatch heating techs throughout Arnold and the surrounding zips — call to confirm availability.
