Why You Need to Have Your Air Conditioner Air Filter Changed

The air filter is one of the simplest parts of the air conditioning system, but it’s also one of the most important. Though many homeowners aren’t even aware that they have an air filter in their AC system, neglecting it can cause serious issues. Let’s take a look at what can happen to your air conditioner if you don’t have your air filter cleaned or changed every few months.

What the Air Filter Does

The air filter sits between the evaporator coil and the air return duct. It is there to prevent dust, dirt, and other debris from making it to the coil and clogging it up. A clogged evaporator coil would cease to function properly, causing some of the same problems that we’re about to talk about. Unfortunately, even though the air filter is good at its job, it has no way of actually getting rid of the debris that it collects. If it is not cleaned or replaced every few months, the air filter will become clogged.

The Problem of a Clogged Air Filter

If the air filter becomes clogged, it will cut off the flow of air to the evaporator coil. This will throw off the temperature balance around the coil, causing it to freeze over. If the coil freezes over, it will cease to function properly. The weight of the ice can permanently warp the coil, requiring that it be replaced. If left alone for long enough, the ice can actually spread to other parts of the system and damage them as well. The best way to prevent this from happening is to have your air filter cleaned or replaced every few months.
