Licensed Furnace Repair service in San Francisco, CA - AAA Pro HVAC

Most furnace repair problems give some warning before they turn into a pilot light that won't stay lit, an ignitor that clicks but never catches, or a furnace that runs but blows cold air — catching it early usually means a shorter, cheaper fix.

The AAA Pro HVAC Difference for Furnace Repair

AAA Pro HVAC built its furnace repair process around one idea: diagnose first, quote honestly, fix it right.

We're licensed, insured, and staffed with techs who've spent years specifically on furnace repair, not general handyman work with an HVAC certificate bolted on.

Furnace Repair Done Right, Every Time

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

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 Francisco, 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 San Francisco, CA.

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 San Francisco, CA.

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 San Francisco, 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 San Francisco, CA.
