Cleaning Out Your Furnace's Combustion Chamber

Posted on

If you have a furnace within your home to heat your house's interior during winter months, doing maintenance to the unit during its off-season will ensure it is ready to use when cooler weather settles in. This will also give you ample time to call a furnace repair specialist should you find damage within the unit that is in need of servicing. Cleaning out the combustion chamber is one task that will help the furnace to run efficiently. Here are some steps you can follow when cleaning out the area on your own.

Take Safety Precautions Before Starting The Job

Before you start the cleaning procedure, make sure the power to your furnace is shut off so it does not come on while you are working. The unit will most likely be plugged into a red or black outlet on the wall behind or next to the furnace. If you are unable to access the outlet, turn off the furnace's circuit breaker at your main circuit control panel.

Scrape Then Vacuum The Interior To Remove Loose Debris

Once power has been disabled to your furnace, open the combustion chamber to assess the amount of debris inside. This is usually in the front of your unit and may require a screwdriver to gain entry to the enclosure. Use a small wire brush to scrape the interior walls, ceiling, and floor of the chamber. Be careful not to scrape the flame igniting area during this process. This will be on the bottom of the chamber. The debris you scrape from the interior will accumulate in the bottom portion of the chamber. Use a vacuum cleaner with an attachment to remove this debris effectively. Wipe the igniting area with a piece of microfiber cloth to remove any debris that settles where the flame is lit.

Add Water And A Detergent To Remove Caked-On Particles

If you still notice areas where soot and ash are still present within the combustion chamber, using a mild detergent can be helpful in removing them in their entirety. Rent a water jet to do the job. This piece of machinery will project water into the area via a small nozzle. Place a mixture of water and detergent in the container portion of the machine and direct the stream toward the affected areas. Use a non-abrasive sponge or wire brush to remove the encrusted debris from the metal enclosure. A clean piece of microfiber cloth can be used to remove the particles that the water jet had removed.
