The Importance of Changing Your AC Air Filter

Do you change your air conditioner filter every three months? If not, you are headed for some serious issues at some point. The air filter is a small part of your air conditioning system, but it’s a very important one. Let’s take a look at what can happen if you don’t change your filter often enough.

The Air Filter

The air filter is a fiber mesh, which is stretched across the air return duct of your system. All dust and other debris that passes into the return duct will become snared in the air filter, protecting the rest of the system in the process. The air filter is quite good at its job, but it has one problem: it can’t rid itself of the debris that it collects. This is why the filter needs to be cleaned or changed every few months. If not, it will eventually become clogged. That’s where the trouble begins.

The Evaporator Coil

The evaporator coil is a part of the air conditioner that evaporates refrigerant in order to absorb thermal energy. This is how your air conditioner cools your home. The temperature around the coil is constantly below the dew point, causing condensation to form on it. The flow of warm air from the home’s ducts prevents the temperature from dropping too low, but that air flow will be cut off if the air filter is clogged. This will cause the condensate to freeze on the coil, icing it over. While the coil is covered in ice, it will be unable to properly siphon thermal energy from the air in the ducts. The ice can also cause malfunctions in other parts of the system, eventually leading to a full system breakdown. This is why you need to change your air filter on a regular basis.
