How to Replace Your Central Air Conditioning Filter

Replacing your central air conditioning filter will provide you with cleaner air, a more efficient and long-lasting system, and lower run times and utility bills. Most homeowners know that they should replace their air conditioner filter every once in a while, but did you know that most experts agree that it should be once every 30-60 days?

How to Remember to Change Air Filter:

Write the date on the air filter itself whenever you switch it out. This way, you’ll know exactly how long it has been since your last filter replacement. Set calendar and phone reminders for 30 days after you replace the filter.

Have plenty of backup HEPA filters and write the month on each one, like this:

Changing your air filter is very easy to do and the benefits are endless. This 2 minutemonthly maintenance task will save you thousands in the long run.

How to Change Your Air Filter:

  1. Find the filter. Sometimes it can be difficult to even find your filter, but all central HVAC systems have one. The most common location is by your air handler, usually low to the ground, where your return ducts meet the air handler. It may be located behind a hinged or sliding panel. For more tips on where it might be, see this air filter location guide.
  2. Check your current filter. If you are unsure if your air filter needs to be replaced, hold it up to the light and see if you can see any light passing through. If you cannot see light coming through, then your air filter is clogged and restricting air flow to your air conditioner. Still, a good rule to live by is to replace your air filter every 30 days.
  3. Choose your new filter. If you the cheapest option, buy the cheapest air filter. If you want cleaner air, less airborne pollutants, and higher efficiency we recommend getting a HEPA (High-Efficiency Particulate Arrestance) filter. HEPA filters meet standards regulated by the United States Department of Energy, removing 99.97% of particles that have a size of 0.3 micrometer or greater. They cost a bit more, but will do a much better job at filtering your air from harmful pollutants. This is especially important for anyone with asthma, allergies, and other respiratory problems. Although HEPA filters cost significantly more, they last about twice as long as more economical filters, needing replacements only every 2-4 months. In addition to their added efficiency, HEPA will end up saving you money in the long run.
  4. Change the filter. After finding, checking, and choosing your filter, take the dirty filter out and replace it with the new one. Put the old filter in a bag and tie it up to prevent the particles from be released back into the air. Take the dirty, old filter to your outside trashcan and dispose of it. When putting the new filter in, make sure that the arrow is pointing with the airflow, towards the blowing motor.
