A furnace that won't ignite, short-cycles, or trips its limit switch repeatedly needs more than a reset — it needs a technician checking the ignitor, flame sensor, and heat exchanger. Every Furnace Repair visit includes a carbon monoxide safety check before we leave, not an upsell.

What Makes Our Furnace Techs Different in Dunbar, SC

Safety and accuracy on every heating call.

CO Testing on Every Visit

A CO safety check with a combustion analyzer is part of every visit, not an optional add-on.

Same-Day Winter Dispatch

We bump no-heat calls ahead of routine work when temperatures drop, especially in peak winter.

Quoted Before Repairs Start

You approve a fixed repair price before any part is replaced, whether it's an ignitor or a heat exchanger.

Trained on Both Fuel Types

Our techs are equally trained on gas furnaces and electric resistance systems, so the fuel type never determines who gets sent.

What Our Furnace Techs Actually Fix

Six repairs that cover most of our winter service calls.

Ignitor & Flame Sensor Service

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 Diagnostics

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.

Heat Exchanger Inspection

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.

Limit Switch & Blower Motor Repair

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.

Pilot Light & Standing Pilot Repair

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.

Thermostat & Wiring Diagnostics

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.

Dunbar Furnace Repair Reviews

Recent reviews from winter heating calls.

★★★★★

Furnace kept shutting off every twenty minutes. The tech 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.

Frequently Asked Questions

What Dunbar customers ask most.

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.

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.

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.
