Every job starts with a real diagnosis, not a guess — here's the full scope of what our furnace repair technicians handle across Waltham, MA.

Ignitor & Pilot Light Repair

Hot surface ignitors crack over time and simply stop glowing — we test resistance rather than replacing on assumption. This is one of the most requested furnace repair calls we get across Waltham, MA.

Gas Valve Diagnostics

A gas valve that won't open or won't seal is tested with proper manometer readings, not just listened to. This is one of the most requested furnace repair calls we get across Waltham, MA.

Heat Exchanger Inspection & Repair

A cracked heat exchanger is a carbon monoxide risk and gets flagged immediately with the furnace shut down if needed. This is one of the most requested furnace repair calls we get across Waltham, MA.

Blower Motor & Limit Switch Repair

A furnace that runs but never blows warm air often traces to a blower motor or limit switch fault. This is one of the most requested furnace repair calls we get across Waltham, MA.

Flue & Venting Repair

Blocked or improperly sloped venting can back-draft combustion gases into the home. This is one of the most requested furnace repair calls we get across Waltham, MA.

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. Techs handling thermostat & control board diagnostics carry the specific parts and tools this job calls for, not a generic kit.

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?+

Could be a delayed ignition fault, a failed gas valve, or a limit switch issue — a full diagnostic narrows it down.

Do you service both gas and electric furnaces?+

Electric resistance furnaces fail differently than gas units, and we diagnose accordingly.

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 Waltham during a cold snap?+

Call dispatch for a live arrival estimate based on current demand.
