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.
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.
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.
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.
Four steps, safety checked at every one.
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.
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.

What Dyer 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.
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.
