We service both gas and electric furnace systems with manufacturer-trained technicians.
Flat-rate pricing quoted after diagnosis, no pressure toward a premature system replacement.
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.

Waiting rarely saves money and often turns a same-day repair into a longer, more involved job.
AAA Pro HVAC built its furnace repair process around one idea: diagnose first, quote honestly, fix it right.
Every truck across Tempe, AZ carries the tools and common parts specific to furnace repair, so most calls finish in a single visit.

Every furnace visit includes a combustion analysis and carbon monoxide test before any repair recommendation.
Our crews are trained on standing pilot, hot surface ignition, and electric resistance furnace systems alike.
No push toward replacement when a repair genuinely solves the problem.
No-heat calls during freeze warnings get moved to the front of the schedule.
From the first symptom to the final fix, these are the specific furnace repair services our Tempe-area crews are equipped for.
Hot surface ignitors crack over time and simply stop glowing — we test resistance rather than replacing on assumption. Techs handling ignitor & pilot light repair carry the specific parts and tools this job calls for, not a generic kit.
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.
We use a combustion analyzer and visual borescope inspection, not guesswork. This is one of the most requested furnace repair calls we get across Tempe, AZ.
We test motor amp draw against rated spec before replacement. This is one of the most requested furnace repair calls we get across Tempe, AZ.
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 Tempe, AZ.
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.

Tell us the symptom — no ignition, cold air, gas smell, or error code — and we route accordingly.
Techs arrive with combustion analyzers and common ignitor/gas valve stock loaded.
Safety check first — combustion and carbon monoxide — then full mechanical diagnostics.
Most ignition and control repairs finish same-visit.

Tech tested the ignitor's resistance right in front of me and swapped it in under thirty minutes.
Old furnace was blowing cold air even though the blower ran fine.
Shut the furnace down immediately for safety and walked me through the options.
Thermocouple was the culprit, replaced and tested before the tech left.

A clicking-but-not-lighting pattern is one of the most common furnace complaints we diagnose.
Yes — it's a genuine carbon monoxide risk and we treat it as a safety issue, not a routine repair line.
