Oil furnace service is unlike other types of furnace services as to the fact that they simply take longer and require additional material to complete properly. We replace the fuel nozzle, adjust the ignitors to proper gap, clean the burner gun, check heat exchanger, clean parts as needed, replace the fuel filter, check operating efficiency, do belt maintenance, check pump coupler, check pump pressure, change air filter, check motors, check ignition transformers, check fire eye, check fuel tank, check safeties and ensure proper ignition.
