Your Easy to Follow Air Filter Replacement Guide

We talked a few weeks ago about why it’s so important to change your air filter every 1-3 months in your air conditioner, but we don’t ever really talk about how to do it. This is an important point to address, since so many homeowners call us or search online for guides to changing their filter. We want to steer you away from an amateur who might not know what they’re talking about, and be your sense of authority on the matter.

Take a look below at our step by step air filter replacement guide and be sure to let us know if you need any more advice or further AC services in San Antonio, TX. Your air filter is vital to the functionality of your AC, and the know-how to replace your filter is great general knowledge to have. So, let’s get started!

Keep This List Handy

If you need to look this step by step guide up on a regular basis, it might be a good idea to print it out and put it on the fridge or on a communal bulletin board. This info should be shared to anyone in your house that might need to replace the air filter in your air conditioner.

Step 1: Turn Off Your Air Conditioner

The first and most important step before you get started in replacing your air filter is turning off the system. The air filter plays an important role in the cooling process, so it’s vital that you don’t let your system run into problems. You’ll have to bear the heat for a second while you replace your filter.

Step 2: Locate Your Air Filter

The air filter is located in most air conditioning units where the air intake grill is. The “air intake grill,” or “return air intake” section of your air conditioner is where the air is brought into the system to be cooled and treated. This can area should be easily visible to you. If you have trouble locating it, make sure you check the system’s manual or call our team for help.

Step 3: Replace the Air Filter

This part is a little tricky. Depending on the brand of air conditioner you have, you’re either going to want to replace the air filter with a new disposable one, or you’re going to need to clean the existing filter. Check the manual of your air conditioner and find where it tells you what kind of filter you have and what you’ll need. If it’s a disposable filter, you’re going to need the right size to replace it. Call us if you have any questions about the type of filter that’s required or if you can’t figure out what to do.

Step 4: Turn on the System

Once you’ve cleaned and replaced the filter, close the system up and turn it on. It should work like a charm! If you notice anything strange, either an unpleasant smell, sound, or something else, don’t hesitate to call us. Whatever you do, don’t start opening up the system further as it could cause more issues and void your warranty. Just call our team!
