Furnace filters are located in different places depending on your system. They can be near your ductwork, near the air handler, or near the furnace cabinet. If you have a new one installed, have your heating technician show you where it is.
Also, determine which size filter works with your furnace. The wrong sized filter won’t fit properly and won’t perform the job as intended.
Next, determine how to correctly place your furnace filter. Furnace filters come with an arrow printed on them. Be sure this airflow arrow is pointing towards the furnace or air handler.
And that’s it. If you have any questions about your furnace filter, just ask. When in doubt, call in a professional to ensure your furnace is operating at its best.
