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.
Common problems and warning signs
- Short cycling — on and off every few minutes
- Loud bang or rumble at start-up
- Rooms furthest from the furnace never warm up
- Grinding or squealing from the blower compartment
- Furnace runs constantly but never reaches the set temperature
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.
Repair or replace?
We don't condemn furnaces to sell equipment. When a replacement is genuinely the right call, you'll get the reason, the options, and a price — with no pressure to decide on the spot.
