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.

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

Techs arrive with combustion analyzers and common ignitor/gas valve stock loaded.
Safety check first — combustion and carbon monoxide — then full mechanical diagnostics.
Heat exchanger findings are documented clearly regardless of outcome.

Tech tested the ignitor's resistance right in front of me and swapped it in under thirty minutes.
Turned out to be a failed gas valve — they caught it with a proper pressure test, not a guess.
Shut the furnace down immediately for safety and walked me through the options.
Thermocouple was the culprit, replaced and tested before the tech left.

Usually a failing ignitor or a fouled flame sensor — both are testable with the right equipment rather than replaced blind.
