What Happens When Your Air Conditioner Filter is Dirty?

A dirty air filter can cause a lot of problems for your air conditioner. It restricts the flow of cold air, causing it to build up inside the air conditioner and lower the internal temperature. This buildup of cold air can cause ice to form on the coils, resulting in poor cold air flow and eventually freezing the system. Before your system completely freezes, there are some telltale signs to watch out for, such as uneven cooling throughout the house.

Additionally, dirt and dust can build up inside the air conditioner, clogging parts and causing damage. To prevent this from happening, it's important to clean or replace your air filter regularly. A vacuum won't be able to remove all the dirt, dust, and allergens trapped between the fibers of the air filter. A dirty filter will cause your HVAC system to work harder than normal and use more energy to cool your home.

It will also allow dust, dander, and debris that should filter into your air duct system. This can lead to costly repairs or a complete breakdown when you need your air conditioner most. To clean the air filter, simply remove it from your oven, remove dirt, and thoroughly clean it by running it in warm water.
