How to Change an AC Filter

We have recently begun repairing AC units. One thing that we’re finding is that many problems can be averted if you take the time to perform some basic maintenance on your AC.

This starts with changing your AC filters before they get too dirty. That means changing those filters at least every 60 days (and every 30 days if you have pets).

Here are the steps you will need to take to change your AC filter.

  1. Locate the air vent. It’s usually in the wall near your thermostat.
  2. Open up the grill.
  3. Pull out the air filter.
  4. Check the size of the filter. You’ll need to buy exactly the same size at the hardware store. A high-efficiency filter will typically give you the best results.
  5. Locate the “air flow indicator arrow.” This is a small arrow on top of the filter. Make sure that points to the interior of the wall.
  6. Fit the filter snugly into place, then close the grill.

As you can see this process isn’t terribly hard.

Now, if you have a central air conditioning unit you may have to change the filters at the AC unit itself. This isn’t a big deal, and the steps are basically the same. Consult your owner’s manual for specific instructions about where your filter is located.
