What are the Effects of a Dirty Air Conditioner?

Dirt can be a nuisance anywhere in your home, but one place that it poses some of the biggest problems is mostly hidden from view: inside your air conditioner. Dirt buildup on your air conditioner can cause huge performance and efficiency problems, which is why you should take steps to keep your system clean. Today we’re going to help you do that by talking about the effects of a dirty air conditioner and what you can do to prevent dirt from building up on your system!


How does an air conditioner get dirty?


When your air conditioner is operating, it pulls in air from your rooms in order to be cooled. As this happens, any dirt that has built up in your rooms can get caught up in your system’s airflow. That dirt travels through your return ducts until it encounters your air filter. If you have a good and clean air filter, the dirt should get trapped by the filter and only clean air should move on past it. If your filter is dirty or inefficient, dirt can bypass your filter and build up on your air conditioner’s components.


Dirt can also build up on your air conditioner’s outdoor unit over time simply due to the fact that it operates outside where dirt and debris are constantly blown around.

How can you prevent your air conditioner from getting dirty?


  1. Get annual tune-ups for your air conditioner. During a tune-up, we’ll perform a full system cleaning on your air conditioner in order to remove any dirt that might have built up since your last maintenance appointment.
  2. Change your air filter every month. Your air filter is responsible for protecting your air conditioner from dirt buildup. In order to ensure it can do its job properly, change your filter every month.
  3. Regularly clean your home. By controlling dirt at its source, you can limit the amount of it that gets caught up in your home’s airflow. Sweeping, vacuuming and wiping your home’s surfaces will all help remove dirt from your home and limit the amount or dirt that your air conditioner is exposed to.
