A dirty filter is one of the most common air conditioning problems that can prevent your unit from working properly. Dirty filters reduce airflow which can lead to other issues, such as the unit freezing up.
When it comes to changing out the filter, it varies. Some units can be monthly, while others can be every 3 months. A good tip to keep track of the condition of each filter is to write the date down on one of the sides of the filter every time you swap it out. In doing this, it will help record the duration of time it takes your unit to dirty a filter, and you won't forget the last time you changed it! Keeping a brand-new filter aside to compare each dirty filter to is a good way to know when it's time for a new one, or if you have a flashlight on hand, you can shine it through to see if light passes through.
You can find single or packs of filters at your local home improvement store, or even your grocery store. Some units might have already come with a washable filter, which you can slide out and clean.
Changing your filter when needed can make the difference in your unit performing efficiently.
