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.
What we usually get called for
- Yellow or lazy flame instead of steady blue
- Rising fuel bills with no change in the weather
- Water pooling near a high-efficiency unit
- Frequent tripped limit switches or a reset button that keeps popping
- Soot or dust around the registers
How we repair it
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.
When replacement makes sense
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 Delaware Township homeowners
- How long does a furnace repair take?
- Most are an hour or two once the diagnosis is done. Parts that have to be ordered are the main reason a job stretches past one visit.
- Is it worth repairing an older furnace?
- Often yes. Age alone doesn't condemn a furnace — a cracked heat exchanger or repeated major failures do.
