Your AC Filter Replacement Guide

Do you need help replacing the filter in your air conditioner? Perhaps you’ve never done it before or you’re scared that you’ll open up the wrong compartment and void the warranty of your system? Don’t worry, we’re here to help. It’s actually a pretty simple process to clean or entirely replace your air conditioner’s filter. As long as you follow along with our handy guide, you’ve got nothing to worry about!

Replacing an air filter is fundamental to Deerfield air conditioning services. It’s something that homeowners should be able to do on their own. That doesn’t mean we can’t help you every step of the way, though!

Make sure you call us if you run into any problems. We’ve tried to address every point down below but there can still be things you encounter that we haven’t mentioned. Our technicians can help you on the phone, as long as you call us!

Follow Along

We’ve tried to make these instructions as clear and easy to follow as possible. Remember to check on the specific type of air filter you’re replacing so you know whether or not you need new, disposable air filters or if you can just clean the existing filter and reinsert it. Make sure you call us if you have any questions!

Step 1: Turn Off the System

You wouldn’t change the oil of your car while it’s still running, would you? Then don’t try to change the filter in your air conditioner while it’s working! Make sure before you do anything to the system, you turn it off so you don’t risk harming any of the sensitive interior components.

Step 2: Locate the Return Air Duct

Your system’s air filter is located in the return air duct. This is the area where all the air from inside your home is inhaled through the system to be cooled and eventually exhaled as cool, comfortable air to be enjoyed. You can usually find it near the air conditioner itself. If you have any questions, make sure you call our team for help.

Step 3: Remove and Replace the Filter

This is the fun part! If you’ve got a disposable filter in your air conditioner, you’re going to want to throw out the old filter and replace it with a new one that’s the right size. You can usually ask a professional or a store clerk to ensure you get the right air filter for the job.

If you’ve got a reusable air filter, then you can just rinse it off or clear it like you would the lint catcher in your dryer. Once you’ve taken away the thin later of dust and debris, it should be ready to be reinserted.

Step 4: Reinsert the Filter

Now you’re going to want to put the air filter back into the system where it can do its job. Take not—you’ll want to make sure you place it back in facing the right way. If the air filter is reinserted incorrectly, it could do a poor job of filtering your air. Align it properly and make sure you take note of which way the filter faces when you take it out so it’s easier to put it back in!

Step 5: Turn the System Back On

Turn the air conditioner back on and feel the difference! If something feels wrong, your next step should be to call us for help!
