Pilot Light Out? Ignitor Failed? Furnace Repair in Derby, CT Fixes It Right

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

Every furnace call starts with a combustion and carbon monoxide safety check, not just a symptom fix.

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.

Furnace Repair Done Right, Every Time

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

Ignitor & Pilot Light Repair

Hot surface ignitors crack over time and simply stop glowing — we test resistance rather than replacing on assumption. This is one of the most requested furnace repair calls we get across Derby, CT.

Gas Valve Diagnostics

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.

Heat Exchanger Inspection & Repair

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 Derby, CT.

Blower Motor & Limit Switch Repair

A furnace that runs but never blows warm air often traces to a blower motor or limit switch fault. This is one of the most requested furnace repair calls we get across Derby, CT.

Flue & Venting Repair

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 Derby, CT.

Thermostat & Control Board Diagnostics

We test low-voltage circuits before condemning the board. This is one of the most requested furnace repair calls we get across Derby, CT.
