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
- 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
What the repair involves
After the repair we run the furnace through a full cycle and check temperature rise, static pressure and draft. A furnace that starts is not the same as a furnace that's right.
If it's time for new equipment
If the heat exchanger is cracked or the unit is past 20 years with repeated failures, we'll say so plainly and quote a replacement. If it has years left, we'll tell you that too — that's the more common answer.
