The Wall, Window or Box Air Conditioner Unit has been around for many years. Also known as window rattlers, these units come in many sizes and have improved overtime. They are however noisy and more expensive than Split Systems.
As with all Air Conditioning systems, these units get just as dirty as the rest. Dirt, Dust and Mould can build up in many areas of the unit and cause performance issues and also health problems.
While the unit performs similar, the cleaning requirements are slightly different. Some units may need to be removed from its mount to be able to be cleaned completely. This is because the area outside of the mount is open to the elements. Additionally the bottom of the unit acts as a catchment tray for moisture extracted from the air. This can cause build up of even mum, mould and sometimes plant growth.
