Oil Furnace Maintenance

Oil furnace maintenance: what an annual tune-up includes, warning signs of trouble, and when replacing oil with a Mitsubishi heat pump makes sense.

  • Inspect, clean and service oil furnace blower assembly, squirrel fan, fan motor, and capacitor.
  • Check and adjust the tension on belt and oil motor.
  • Replace nozzle, and oil filter (spin on filter cartridge extra), all high and low voltage wiring.
  • Inspect contact, burner relay, burner motor, coupler, fuel pump pressure, electrodes, vent pipe, supply and return plenums.
  • Brush and clean furnace flue and vent pipe to chimney.
  • Replace furnace filter (customer to provide or replacement is extra).
  • Thermostat and combustion test.

Oil-burning furnaces need more maintenance than gas furnaces due to soot and grime build-up that comes naturally in an oil-powered model. Your oil furnace should be cleaned and checked twice each heating season and serviced by a professional each fall.

INSPECTION CHECKLIST
Here are 3 things you can do between professional inspection appointments to make sure your unit is running smoothly. However, if you’re not comfortable working on or near an oil furnace motor, you can always call, and reduce the risk of error or damage to your unit.

1. LOOK
Look for signs of black soot around your furnace. Soot outside the furnace itself could mean that the unit is burning more than oil. You should also look at the smoke coming from your chimney while the furnace is burning; black smoke could indicate that the oil is not being burned completely.

2. LISTEN
Listen for any unusual vibrating or rattling sounds coming from the furnace blower. If you notice any of these signs, contact your local.

3. CHANGE
Remember to change the air filter in your furnace as often as recommended by your operator’s manual, or more frequently if you own pets.
