Our Full Range of Furnace Repair Services

From the first symptom to the final fix, these are the specific furnace repair services our Sun Prairie-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. This is one of the most requested furnace repair calls we get across Sun Prairie, WI.

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.

We use a combustion analyzer and visual borescope inspection, not guesswork. Techs handling heat exchanger inspection & repair carry the specific parts and tools this job calls for, not a generic kit.

We test motor amp draw against rated spec before replacement. This is one of the most requested furnace repair calls we get across Sun Prairie, WI.

Furnace Repair FAQ

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?+

Gas odor calls receive top dispatch priority.

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

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