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. We test each with a multimeter and combustion analyzer rather than replacing parts on a hunch.
Safety and accuracy on every heating call.
A CO safety check with a combustion analyzer is part of every visit, 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.
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.
A furnace that short-cycles or shuts down mid-cycle often points to a tripped limit switch or failing blower — 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.
What happens from your call to heat restored.
Tell us what the furnace is doing and we'll route the closest technician.
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 Cool 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.
Every furnace call includes a CO check with a combustion analyzer, no extra charge.
We still service standing-pilot units, including thermocouple and draft-related repairs.
We prioritize no-heat situations, usually landing a same-day slot even during high-demand cold weather.
Common failure parts ride on the truck already; something unusual might mean a next-day return visit to complete the repair.
