Furnace Repair in Tustin, CAFrom Techs Certified on Gas and Electric Units

Name: AAA Pro HVAC
Telephone: +1-866-805-8548
Price range: $$
Rating: 4.9

We service both gas and electric furnace systems with manufacturer-trained technicians.

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

If you're dealing with a pilot light that won't stay lit, an ignitor that clicks but never catches, or a furnace that runs but blows cold air, you already know 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.

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 Tustin, CA.

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 Tustin, CA.

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 Tustin, CA.

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 Tustin, CA.

Blower Motor & Limit Switch Repair

A furnace that runs but never blows warm air often traces to a blower motor or limit switch fault. Techs handling blower motor & limit switch repair carry the specific parts and tools this job calls for, not a generic kit.

Flue & Venting Repair

We inspect the full flue run, not just the connection at the furnace. This is one of the most requested furnace repair calls we get across Tustin, CA.

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. This is one of the most requested furnace repair calls we get across Tustin, CA.
