How often should I change my filter?
If your Honeywell, 3M, Filtrete, Trane, or Lennox filters look like this two filter, it's time for a change! Common filters are either 1" pleated, or non-pleated but pleated filters need to be changed every two months. Most manufacturer intervals are typically no longer than 90 days, but if you can get in the 60 day habit of changing your Honeywell, 3M, Filtrete, Trane, or Lennox filter you will be better off. Common filter-caused repair issues can cause a Trane, Lennox, Bryant, Day and Night, Goodman, Amana, or Rheem furnace to stop working in the colder weather that is coming. Coming into the furnace season, put reminders on your phone or calendar. Sometimes the filter access is in the duct, sometimes the filter access is in the furnace, but be sure to change the filter on a regular basis!
