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.
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.

No push toward replacement when a repair genuinely solves the problem.
We understand a dead furnace in winter is a pipe-freezing risk, not just a comfort issue.
From the first symptom to the final fix, these are the specific furnace repair services our Petersburg-area crews are equipped for.
Standing pilot systems get checked for thermocouple failure, the most common cause of a pilot that won't hold. Techs handling ignitor & pilot light repair carry the specific parts and tools this job calls for, not a generic kit.
Faulty gas valves are treated as a safety-critical repair, prioritized accordingly. This is one of the most requested furnace repair calls we get across Petersburg, NY.
We use a combustion analyzer and visual borescope inspection, not guesswork. This is one of the most requested furnace repair calls we get across Petersburg, NY.
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.
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 Petersburg, NY.
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 Petersburg, NY.

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.
Heat exchanger findings are documented clearly regardless of outcome.

Furnace kept clicking like it wanted to light and never catching.
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.
Pilot light kept going out every few hours.

Usually a failing ignitor or a fouled flame sensor — both are testable with the right equipment rather than replaced blind.
Yes — it's a genuine carbon monoxide risk and we treat it as a safety issue, not a routine repair line.
This symptom shouldn't be ignored since it sometimes points to a safety-related fault.
Electric resistance furnaces fail differently than gas units, and we diagnose accordingly.
Immediately — leave the area and call, don't attempt to diagnose it yourself.
