In order to refrain from overworking your furnace, it is important to change your furnace filter on a regular basis. Filters prevent HVAC appliances like furnaces and air conditioning units in Portland from circulating dust and debris throughout the house. Watch this video for a few tips on how to change your furnace filter.
Many furnace filters are found behind grills located within your walls. Remove the grill to access your filter and take a look at its condition. If your filter appears to have a buildup of dust, dirt, and other debris, it is time to replace it with a new one. Pull out your filter and check its size so that you can find a proper replacement. Look at the arrow on your new filter; this will indicate which direction the filter should be facing. Now you can simply slide in your new filter and close the grill.
