How to Change Your AC Filter Easily

Are you looking for an easy way to keep your home's air clean and free of dust, pollen, and other allergens? Replacing your air conditioner filter is a simple task that can help you do just that. It also prevents dirt from entering the system and wearing it out more quickly. Here's what you need to know about how to change your AC filter.

Step 1: Find the Right Replacement Filter

The first step in replacing your air conditioner filter is finding the right replacement filter. You'll need to know the size of your existing filter, as well as the type of filter you need (pleated, fiberglass, high-efficiency, etc.). If you don't know what size or type of filter you need, take a look at your owner's manual or contact the manufacturer. Once you have the right one in hand, make sure it fits snugly into place.

Step 2: Remove Your Old Filter

Now that you have the right replacement filter ready to go, it's time to remove your old one. Start by turning off power to your air conditioner - either switch off its breaker or unplug it from its outlet. Then locate its filter compartment - usually behind a removable panel on its side - and carefully pull out the old one without damaging any wiring or components.

Step 3: Clear Out Any Debris

Before installing your new filter, take some time to clear out any debris that may have accumulated inside its compartment. Use a vacuum cleaner with an attachment hose for this purpose; this will help ensure that no dust or dirt clogs up your new one.

Step 4: Install Your New Filter

Once all debris has been cleared away from inside its compartment, it's time for installation! Make sure that it fits snugly into place and doesn't move around when closing up again; if necessary, adjust until secure.

Step 5: Turn On Your Air Conditioner Again

Finally, turn on power back on for your air conditioner and check whether everything is working properly. You may want to run it for a few minutes just in case.


Replacing an air conditioner filter is an easy task with many benefits. With just these few steps, you can easily replace an old one with a new one so that everyone can enjoy cool, clean air!
