The Purpose Of The Air Filter In Your Central Air Conditioning System

Posted on

If your home has a central air conditioning system, there is most likely a compartment near the system that contains an air filter. An air filter is a vital part of a central AC system, and it is something that you should change on a regular basis. The air filter serves several functions, but it cannot operate well if it is dirty. Here are a few things to understand about the air filter in your AC system.

It filters out debris from the air

The first purpose of the air filter is to remove dust, dirt, and debris from the air in your home. All the air in your home gets pulled through the AC system and is then sent back into your home after it is cooled. The air filter helps keep your AC system by removing a lot of the debris from the air before the air gets inside the system to be cooled.

This process also helps keep your home less dusty. As it pulls dust out of the air, the conditioned air is left cleaner, and this is the air that ends up in your home. A clean air filter is great at completing this task.

It can prevent the AC system from working properly

When the air filter in your system gets full of dust and dirt, it may prevent your AC system from functioning properly. This occurs primarily because the AC system needs airflow in order to extract heat out of the air as a way of cooling the air. As the filter gets dirty, it begins restricting airflow to the system. This makes it harder for the AC system to cool air, and this can lead to inefficiencies with your system. It's likely that your home may not be as cool as it should be if the air filter is dirty, and you may even see an increase in your energy bills from this.

You must change it as often as needed

To make sure your system is working at its best, it is your responsibility to replace the air filter anytime it is needed. There really isn't a set schedule that works perfectly for every home, and this is because there are a lot of factors that affect how often you should change your filter. For example, if you have pets in your home or if someone in the house smokes, you will need to change your filter more often. You should get in the habit of checking it every month and replacing it if it appears dirty.
