Oil Furnace Repair & Service

Prevent serious problems with regular servicing and timely oil furnace repair

Oil furnaces are longer lasting than other furnace options like gas, but they do require occasional maintenance, ideally from a professional. Most notably, the oil filters will need to be changed regularly and the system as a whole should be cleaned from time to time. This occasional maintenance can go a long way towards preventing more serious issues later down the line and can provide an opportunity to discover other potential issues early, while the repairs are still simple and inexpensive.

If your oil furnace does develop a problem, don’t wait to reach out to your local HVAC contractor. Many small furnace problems will grow worse if ignored and the last thing you want is to be without heat in the middle of winter.

Common reasons for oil furnace repair

  • Burner Not Working: This is the broadest category with a wide range of possible causes. The cause could be as simple as a thermostat set too low or a lack of fuel/electricity. If none of the obvious causes are to blame, then the issue is likely due to a plugged nozzle, blocked filter, clogged oil line, weak transformer, or broken oil pump. There are other possibilities as well, so it’s always best to contact a professional who can perform a more in-depth analysis and make the required repairs afterward.
  • Odors/Fumes: If you are noticing odd smells or fumes, you might have a plugged nozzle or cracked heat exchanger. Other possibilities include a dirty chimney, burner in need of adjustment, or items too close to the furnace/smoke pipe.
  • Odd Noises: Often you can tell the type of problem your furnace has based on the type of sound. Rumbling generally indicates an incorrectly set pilot light or dirt in the burner, whistling suggests filter issues. A high pitched screeching or squealing generally indicates an issue with the belt or blower motor. Grinding is the most serious sound and you should shut off your furnace immediately if you hear it. This sound usually indicates serious internal problems, normally with the motor bearings.
