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.
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.
Ignitor or heat exchanger, the price is quoted and approved before work begins.
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.
Cracked ignitors and carbon-fouled flame sensors account for a large share of no-heat calls, 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.
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.
We still service standing-pilot furnaces, checking thermocouple output and draft conditions that newer ignition systems don't have.
Zero response from the furnace can mean a wiring fault or thermostat issue rather than the furnace itself — 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.
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.

What Berlin customers ask most.
Clicking or humming without ignition often points to the ignitor, though we always confirm with a proper resistance reading 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.
Common failure parts ride on the truck already; something unusual might mean a next-day return visit to complete the repair.
