It is essential to clean the oil furnace heat exchanger since burnt oil leaves soot deposits that block heat transfer from the combustion chamber.
When soot insulates the sides of the heat exchanger, you get less heat in the home.
To clean the oil furnace heat exchanger, you first have to switch off the power supply. This will protect you from electrocution and accidental burns during the cleaning process. To access the parts of the oil furnace that should be cleaned, you will use your screwdriver to remove the metal panel that covers the furnace. Expose the heat exchanger by removing the flue vent connector and covers. Inspect the interior for any damage. Vacuum, brush, clean the soot and debris and then inspect again for damage. Next, evaluate the amount of dirt on the filter. Replace your filter if it is extremely clogged. Get a replacement at a local hardware store. You can take your old filter to them so that they provide the exact filter replacement. The next step is to loosen the screws and bolts that attach the fan unit to the furnace. Then remove all debris and dirt using a vacuum cleaner. Use a brush to brush away stubborn dirt gently. Use the vacuum one more time to remove all the debris that has fallen from the surfaces. Don’t leave any dirt after cleaning. Remember to clean the fan blades as they collect a lot of dirt and debris. The fan blades should be brushed gently and soaked in warm soapy water to loosen the dirt. Dry the blades with a rag and ensure all corners and edges are clean. You can now replace the fan and the oil filter. Secure the fan in place with bolts and screws. Put the new or cleaned filter back into its place. Screw back the cover once all the pieces of equipment are in place. Finally, turn on the power source to see if the furnace is working properly.
