Our Full Range of Furnace Repair Services

From the first symptom to the final fix, these are the specific furnace repair services our San Marcos-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 San Marcos, TX.

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 San Marcos, TX.

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 San Marcos, TX.

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. This is one of the most requested furnace repair calls we get across San Marcos, TX.

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?+

This symptom shouldn't be ignored since it sometimes points to a safety-related fault.

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 San Marcos during a cold snap?+
