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. We test each with a multimeter and combustion analyzer rather than replacing parts on a hunch.
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.
We test gas valve response and pressure output rather than replacing an expensive part on a hunch, 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.
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.
We run the safety and diagnostic checks first, then present a flat-rate quote for your approval.
Repairs typically wrap same visit, and we re-check CO levels before signing off, backed by our labor warranty.
Recent reviews from winter heating calls.
Furnace kept shutting off every twenty minutes. Their technician found a dirty flame sensor and cleaned it, been running fine for two months now.
— B. Halloran, homeowner
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.

What Marion customers ask most.
Clicking or humming without ignition often points to the ignitor, though we always confirm with a proper resistance reading 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.
