Keeping your furnace clean is an important step in maintaining it. If a furnace is dirty, it can burn higher amounts of electric and/or gas fuel or work less effectively. A build up of dirt can cause problems in 3 areas of the furnace such as the filter system, the blower, and the heat exchanger. If left uncleaned it can cause further damage, and possibly result in the need for a new furnace. You should familiarize yourself on how to effectively clean each area of the furnace for continued furnace maintenance to keep it running smoothly.
Turn off the unit
Make sure the unit is turned off before performing any maintenance. Locate the access panel on the outside of the furnace and remove it so you can inspect the furnace thoroughly.
Inspect for damage
Inspect the filter for dirt or damage by holding it up to a light. If the filter appears dirty, it needs to be cleaned or replaced. If a filter is dirty, it will dust and debris throughout your home causing poor air quality.
If your filter is not disposable, remove any dirt with mild soap and water. Clean out all dust and debris from the furnace itself by using a vacuum around the motor and blower. In the smaller or wider areas of the furnace you may need special tools to get a deep clean depending on your unit. Vacuum/clean ducts and make sure there are no leaks. Apply the necessary motor oil before closing the furnace back up.
Remember that you should inspect your filter regularly. Furnace filters should be changed or cleaned three or four times a year to avoid costly furnace repair. Set a reminder on your calendar.
