If you aren’t quite sure how to replace the AC filter or don’t know if your filter needs to be changed yet, you’ve come to the right place! Here’s a step by step guide on how to identify a filter that needs changing and how to change it yourself.

4. Line Up Filter

This may be the most important aspect of replacing the filter. Once you’ve determined that a new filter is necessary, be sure to line it up in order to allow the air to flow well through the filter.
