Combustion & CO Safety Checks

Every furnace visit includes a combustion analysis and carbon monoxide test before any repair recommendation.

Gas & Electric Certified Technicians

Flat-Rate Furnace Pricing

Diagnosis happens first, and the quoted flat rate reflects the actual confirmed fault.

Cold-Weather Priority Dispatch

Furnace Repair Done Right, Every Time

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

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 Mount Prospect, IL.

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 Mount Prospect, IL.

Blower Motor & Limit Switch Repair

We test motor amp draw against rated spec before replacement. Techs handling blower motor & limit switch repair carry the specific parts and tools this job calls for, not a generic kit.

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.

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.
