Certified Gas & Electric Furnace Technicians
Safety-First Furnace Diagnostics

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

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 San Diego, CA get treated with urgency, not a next-available-Tuesday slot.

Licensed Furnace Repair service in San Diego, 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.

A cracked heat exchanger is a carbon monoxide risk and gets flagged immediately with the furnace shut down if needed. This is one of the most requested furnace repair calls we get across San Diego, CA.

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.

Common Furnace Repair Questions in San Diego, CA

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?+

Could be a delayed ignition fault, a failed gas valve, or a limit switch issue — a full diagnostic narrows it down.

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 Diego during a cold snap?+
