Pilot Light Out? Ignitor Failed? Furnace Repair in Durham, NH Fixes It Right

We service both gas and electric furnace systems with manufacturer-trained technicians.

Flat-rate pricing quoted after diagnosis, no pressure toward a premature system replacement.

If you're dealing with a pilot light that won't stay lit, an ignitor that clicks but never catches, or a furnace that runs but blows cold air, you already know furnace failures carry a safety dimension — carbon monoxide and gas leaks — that most other HVAC repairs don't, so the diagnostic has to start there.

Our Full Range of Furnace Repair Services

From the first symptom to the final fix, these are the specific furnace repair services our Durham-area crews are equipped for.

Ignitor & Pilot Light Repair

Standing pilot systems get checked for thermocouple failure, the most common cause of a pilot that won't hold. Techs handling ignitor & pilot light repair carry the specific parts and tools this job calls for, not a generic kit.

Gas Valve Diagnostics

A gas valve that won't open or won't seal is tested with proper manometer readings, not just listened to. Techs handling gas valve diagnostics carry the specific parts and tools this job calls for, not a generic kit.

Heat Exchanger Inspection & Repair

We use a combustion analyzer and visual borescope inspection, not guesswork. This is one of the most requested furnace repair calls we get across Durham, NH.

Blower Motor & Limit Switch Repair

A furnace that runs but never blows warm air often traces to a blower motor or limit switch fault. Techs handling blower motor & limit switch repair carry the specific parts and tools this job calls for, not a generic kit.

Flue & Venting Repair

We inspect the full flue run, not just the connection at the furnace. This is one of the most requested furnace repair calls we get across Durham, NH.

Thermostat & Control Board Diagnostics

A furnace that won't respond to the thermostat at all sometimes traces to a control board fault rather than the burner assembly. This is one of the most requested furnace repair calls we get across Durham, NH.

Before You Call: Furnace Repair Answers

Why does my furnace click but never actually light?+

Usually a failing ignitor or a fouled flame sensor — both are testable with the right equipment rather than replaced blind.

Is a cracked heat exchanger dangerous?+

Yes — it's a genuine carbon monoxide risk and we treat it as a safety issue, not a routine repair line.

Why is my furnace running but blowing cold air?+

This symptom shouldn't be ignored since it sometimes points to a safety-related fault.

Do you service both gas and electric furnaces?+

Yes — our technicians are trained and certified on both fuel types.

How urgently should I call if I smell gas near my furnace?+

Immediately — leave the area and call, don't attempt to diagnose it yourself.

How fast can a furnace tech reach Durham during a cold snap?+
