  • Turn off the electrical and fuel supply before working on your furnace

    • The electrical supply is usually a red switchplate near the stairs or the burner
    • The fuel supply is usually near the oil tank or the incoming gas pipe

  • Electrical and fuel supply has been turned off


  • If you are unable to clean the furnace thoroughly, contact a professional

  • Sweep or vacuum dust from around the furnace and registers so air can flow freely

  • Vacuum the burners and around the base of the furnace

  • Use a flashlight to spot any soot that’s collected, indicating poor combustion

  • Remove the bolts securing the blower and gently lift it out

  • Use a small brush and vacuum to clean the blower blades properly

  • Remove the lower door and vacuum the blower compartment

  • Clean the belts and pulleys that lead to the blower

  • Vacuum the heat vents in your home (do this annually before winter begins)

Replace Disposable Filters

  • Open the filter access and remove the filter

  • Check the filter size and type and note this on or near the furnace in permanent marker

  • - If you use a pleated or polyester filter, change every three (3) months
    - If you use a fiberglass filter, change it monthly
    - If you smoke inside or have pets, change it each month regardless of filter type
    - For a permanent filter, follow the manufacturer’s instructions, attached to the furnace itself

  • Place the old filter in the trash, not the recycling

  • Close the filter access, using the clasps to ensure it remains shut


  • Ensure the combustion air openings are not blocked or restricted

  • Inspect the flue pipe for corrosion or leaks

  • Check the drive belt leading to the blower for any cracks or frayed edges

  • Use a straw to remove dust from the pilot

  • Use an emery cloth to clean the flame sensor and reinsert into the proper bracket

  • Check the vents for rust and leaky water

  • Keep an eye out for loose panels as these can raise your heating bill or cause your furnace to shutdown

  • Look to see that drain lines are clear and draining properly

  • Have a look at your electronic thermostat to see if the batteries need to be changed

  • If you use the same vents for heating and air conditioning, there may be a setting to adjust the dampers based on season.
