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.
Furnace failures cluster heavily around a handful of parts — ignitors, flame sensors, gas valves, and heat exchangers — and most no-heat calls come down to one of those four. 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.
We bump no-heat calls ahead of routine work 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.
Whether the furnace runs on gas or electric heat strips, our techs are trained on both, so the fuel type never determines who gets sent.
Six repairs that cover most of our winter service calls.
Cracked ignitors and carbon-fouled flame sensors account for a large share of no-heat calls, 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.
Because a cracked heat exchanger can leak combustion byproducts into the home's air, we inspect it carefully with a scope and 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.
We still service standing-pilot furnaces, checking thermocouple output and draft conditions 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.
What happens from your call to heat restored.
Tell us what the furnace is doing and we'll route the closest technician.
Truck arrives stocked with common ignitor, flame sensor, and control board parts 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. Their technician 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.
It's a genuine safety concern since it can let combustion byproducts into the airflow, 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.
