What furnace repair involves
Repairing a furnace properly means confirming why the part failed, not just that it failed. A flame sensor that fouls every winter is telling you something about combustion or filtration.
Diagnosis and repair of gas, propane and oil furnaces — ignition, flame sensors, blowers, boards and heat exchangers.
Signs you need service
- Blower runs but the air is cold
- Furnace lights, then shuts down after a few seconds
- Clicking or repeated attempts to ignite
- Burning or hot-metal smell when it runs
- Thermostat calls for heat and nothing happens
What the repair involves
Most repairs come down to ignitors, flame sensors, pressure switches, inducer motors, blower motors or capacitors, control boards, and gas valves. We show you the failed part and explain what it does before we install a replacement.
If it's time for new equipment
Replacement makes sense when repair costs stack toward a large fraction of a new system, or when the exchanger is compromised. Short of that, repairing a well-built older furnace is usually the better use of your money.
Questions from Sussex Borough homeowners
- Can you come out the same day?
- For a no-heat call we try to, and voicemail gets a same-day callback. Leave your name, address and what the system is doing.
- Do you work on oil furnaces?
- Yes — gas, propane and oil. Say which one you have when you call so the right parts are on the truck.
