Certified Gas & Electric Furnace Technicians
Safety-First Furnace Diagnostics

Certified Furnace Repair Across Lexington, MI

Every furnace call starts with a combustion and carbon monoxide safety check, not just a symptom fix.

Heat exchanger cracks, ignitor failures, and gas valve issues all fall within our scope.

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, which is exactly why furnace repair calls in Lexington, MI get treated with urgency, not a next-available-Tuesday slot.

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 Lexington, MI.

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. Techs handling heat exchanger inspection & repair carry the specific parts and tools this job calls for, not a generic kit.

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 Lexington, MI.

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.
