Comprehensive Furnace Repair Solutions

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

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 Fenton, MO.

Gas Valve Diagnostics

Faulty gas valves are treated as a safety-critical repair, prioritized accordingly. This is one of the most requested furnace repair calls we get across Fenton, MO.

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 Fenton, MO.

Flue & Venting Repair

Blocked or improperly sloped venting can back-draft combustion gases into the home. Techs handling flue & venting repair carry the specific parts and tools this job calls for, not a generic kit.
