Keeping Your Air Clean with the Right AC Filter

Having a clean air conditioning filter in your home is essential for keeping your air fresh and reducing energy costs. But it’s important to make sure you replace it correctly. Here are some tips on how to do just that.

The Benefits of Replacing Your Filter

Your AC filter works hard to capture dirt, dust, and other particles from the air. Over time, these particles accumulate on the filter, making it less effective. If you don’t replace your filter regularly, you could end up with poor indoor air quality, higher energy bills, and even system damage.

When Should You Replace It?

How often you need to change your AC filter depends on the type of filter you have and how much pollution is in your home. Generally speaking, most filters should be changed every three months. If there are pets or high levels of air pollution in your area, then more frequent replacements may be necessary.

Replacing Your Filter: Step by Step

The process for replacing an AC filter is relatively straightforward. First off, locate the housing unit which can usually be found near the return duct or blower motor. Then unscrew any screws holding it in place and remove the old one.

Next, measure out a new one that fits properly into the housing unit - make sure to get one with an appropriate MERV rating for optimal performance! Once that’s done, slide it into place and secure with screws before turning on your system again.

Other Maintenance Tips

In addition to replacing your AC filter regularly, there are a few other maintenance tasks that should be done periodically, such as cleaning condenser coils, checking refrigerant levels, and making sure all electrical connections are tight.

Performing regular maintenance will help keep things running efficiently, reduce energy costs, and improve indoor air quality, so don't forget about them!


Replacing an AC filter is an important part of maintaining its performance, so make sure you do it correctly following these steps! Doing so will help keep your air clean, reduce energy costs, and prolong its life span.
