The air filter is one of the most vital parts of your home's air conditioning system. This is also the easiest part of the system to maintain yourself. However, some homeowners overlook air filter maintenance, while others feel more intimidated by doing it themselves. Here is some information you should know about the air conditioners filter:

Why Are Clean Air Filters Necessary?

The air filter prevents any dust, debris, and contamination from getting into your indoor air. The filters work to make the system more efficient, helps it last longer, and prevents dust buildup on the components inside the system.

Air filters also keep yourself and those who live in your home healthy. An air filter will catch the particles that you could breathe into your lungs. Air filters also help you save on your electric bills, as the system does not have to work as hard to cool your home.

When Should You Change Your Air Filter?

You should consult the owner's manual for your HVAC system, as some systems require more or less frequent air filter changes than others. In general, you should check your air filter every few months to see if it needs changing. You may want to check your filters more often if you live in a dusty climate, as dust tends to collect on air filters more frequently.

What Do the Air Filters Prevent?

Even if your home seems clean, there will always be something flowing through the air in your home. Some of the contaminates that will collect in an air filter include outdoor plant debris, pollen, pet dander, dust, skin cells, and the like.

How Can You Tell If Your Air Filter Is Clogged?

If you do not or cannot check your air filter, there are some clear signs that it is dirty and potentially clogged. The grate inside that covers your HVAC system will collect dust and debris from inside your house. If you see any visible dust, your air filter is likely dirty.

If you see a heavier buildup on your furniture in your home or notice more dust particles floating in the air, there is a high likelihood that your air filter is dirty. If the air conditioner continues to cycle more often than it had before, your air filter needs to be changed. This is because the air is not cooling as efficiently because the air cannot flow through the system as well.
