How to Change a Furnace Filter
November, 18th, 2020
Your furnace filter is one of the most basic parts of your HVAC system, but many people forget about it unless it’s causing a problem. Changing your furnace filter is an important part of furnace maintenance that you can perform yourself. Read on to learn more about changing your furnace filter!
Where is My Furnace Filter?
Depending on the age, manufacturer, and style of your furnace, your filter might be located in one of several different places. The filter’s location is often labeled on the unit, though sometimes you might have to look up how to access it in the manual.
Older furnaces may have a door built into the side of the unit. Remove this to replace the filter. You can pop it off or unscrew it to access the older filter. Slide out the old filter, make sure your new one is the same size, and slide it back in until it fits just like the old one did.
The filter size is always available on the side of the filter. It may also be included in your manual or written on a label near the filter.
Newer filters may have a filter base installed. This will usually be labeled and the label will include the size of filter that you need. Flip up the access panel, slide the old filter out, and slide the new one back in.
When Should I Change My Furnace Filter?
You should change your furnace filter monthly, or every other month, for optimal system functioning and to keep your system from experiencing extra wear and tear. A good rule of thumb is to change your furnace filter every time you get a utility bill. Use it as your reminder to make sure that your furnace is in great shape!
