DIY oil furnace maintenance

Lubrication, cleaning and changing of filters should be part of the DIY maintenance of your oil furnace. Also inspect the chimney stack for possible leaks. You will get important energy savings and prevent safety hazards.

Filters

See the owner’s manual for details on how to change the filters of your oil furnace. Periodic change of the air and fuel-oil filters is crucial for energy savings.

Leaks

Check for possible leaks at the fuel storage tank. Look for dripping or signs of oil. Leaks should be fixed immediately.

Noise Tips

Odd noises on your oil furnace should be inspected. They may be caused by problems in the burner (a reason for calling a heating professional) by a loose access panel or damaged belts (in the blower).

Lubrication and electrical components

Pay attention to the motor parts. Lubricate them at the beginning and middle of the heating season. Remove any possible dust and dirt. Use proper lubrication oil. Inspect oil leaks and smudges on the burner mounting plate. Take into account the owner's manual.

Inspect the visible wiring and other electrical connections for cracked elements, burns or cracked and loose wire nuts and tape. In case of smudges on the burner mounting plates or blackened areas in the electrical components, call a professional.

Smoke, chimney and exhaust stack

Inspect the smoke in the chimney stack of your oil furnace. Black smoke is a sign that the furnace is not tuned up.

Also inspect the exhaust stack. Look for leaks and holes.

Look for rust or gaps in the vent connections and chimney. The parts of the venting system can deteriorate over time.

Call a technician, if it is the case. Leaks are dangerous and pollutants.

DIY cleaning task

Inspect the thermostat and the stack control as well as the blower, and clean them. The blower and the stack control should be cleaned and checked at least two times throughout the season.

Troubleshooting

Pay attention to some common and simple problems that any DIYselfer can perform like maladjustments in the thermostat, lack of oil in the tank and clogged air and oil filters and blower.
