Sanborn’s Air Conditioning & Heating admits it. We tend to “beat people up” by reminding them incessantly about the importance of changing their HVAC filters on a regular basis. It’s one of the few things the non-professionals can do to prevent HVAC repairs. For the most part, maintenance and upkeep of your home’s HVAC system should be left to professionally-licensed heating and cooling technicians.
Of course the million-dollar question here is, just how often is regularly? The answer depends on a variety of factors, including what type of climate/environment you are living in and what kind of furnace filters you use.
Typically the cheaper fiberglass filters should be changed every 30 days. More effective pleated filters are usually expected to last up to 60 days. Please remember those are general guidelines. Sanborn’s has put together a list of questions to help determine if you should change your filters more often:

  1. Do you live in a dusty environment or in a location with poor air quality?
    If so, more dust likely gets into your home and is trapped by your air conditioning and furnace filters, and they should be changed more frequently.
  2. Do you have pets?
    Clean filters will remove more pet dander and odors from the air. The more pets you have, the more often you should consider changing the filter.
  3. Does anyone in your home suffer from allergies or respiratory issues such as asthma?
    They are affected much more by poor indoor air quality and to assure their comfort you should consider reducing the amount of time between filter changes.
  4. How often does your system run?
    If your system is running just an hour or two a day because you live in a mild or temperate climate, your filter will last longer. Of course, during summer in Southern California your system could be running nearly continuously and you may want to change your filter every two or three weeks.

The smart thing to do is an old-fashioned visual inspection every few weeks. A small coating of dust, with the fibers of the filter still visible means you can wait a while longer. If you see a thick layer of dust it’s time to change. The important thing is to err on the side of better safe than sorry. Filters are cheap compared to the cost of premature HVAC repairs.
