8 Steps to Follow When You Clean a Furnace

1. Deactivate the Power & Gas

The first step in cleaning your furnace is safety. Before cleaning anything, turn off the power to the
furnace. If your unit is connected to natural gas, shut that off as well. Only continue with the next
steps once you’re certain that everything is off.

2. Clean the Outside

Part of ensuring a functioning furnace is keeping the furnace’s exterior clean, too. Dust or
debris on the pipes that feed into your furnace can cause issues. Prevent this by cleaning the
exterior of any ducts, pipes, or electrical conduit that lead to the furnace with a vacuum cleaner
brush attachment. A feather duster can clean more delicate objects like electrical connections.

3. Wash the Blower Motor

The next step to follow when cleaning your furnace is to wash the blower motor. Take off the metal panel and remove the blower from the main unit. To clean the blades, use a stiff brush and warm soapy water.

4. Clean the Heat Exchanger

A furnace turns cool air into hot air using a heat exchanger. This important piece needs to be
properly cleaned to ensure the furnace functions properly. Do another safety check to ensure it is completely cooled off before cleaning. Then use a stiff brush to dust off any debris.

5. Check the Air Filter

A dirty air filter can cause suboptimal efficiency. A reusable filter can be cleaned of dust or debris. A
disposable filter can simply be replaced with a new one.

6. Inspect & Clean the Flame Sensor

The flame sensor is a small metal rod typically on the right side of the furnace. The next step to follow when you are cleaning your furnace is to remove the flame sensor and use a cloth to eliminate dirt or debris.

7. Check the Drive Belt Tension

Check that tension on the blower unit belt deflects between ½ inch to ¾ inch. While inspecting the tension, ensure the belt has no frays or cracks. Frays or cracks in the belt will result in lower tensions and the furnace performance will suffer.

8. Lubricate

Lastly, add 2-3 drops of light machine oil to the blower motor unit and the shaft bearing.
