Furnace and Air Conditioner
Monthly/Yearly Checklist


  • Replace filters monthly. If dirty or clogged, replace with a filter that is the same size.
  • To change filter, open up the return air panel, usually it is near the “boot” that connects from the ceiling to the side of your furnace.
  • Or look for your “Filter Rack”, probably located on left side of furnace.
  • Pull out the old filter to inspect. If dirty, replace with new filter.If it has been over a month, replace it, because it could have dust or sheet rock dust in it that looks clean.
  • Important! Make sure arrow is pointing the direction of the airflow, otherwise it will restrict air flow and cause problems for your furnace.
