Same-Day Furnace Repair Across Key Largo, FL

Name: AAA Pro HVAC
Telephone: +1-866-805-8548
Price range: $$
Rating: 4.9

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.

Our Full Range of Furnace Repair Services

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

Ignitor & Pilot Light Repair

Gas Valve Diagnostics

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 Key Largo, FL.

Furnace Repair FAQ

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 Key Largo during a cold snap?+
