G’day in this video we are going to go through and show you how to completely stripped down the air conditioning unit, still leaving the refrigeration coil in place with refrigerant it. This is how we do a Defaul, that’s where we clean all the components of the airconditioner indoor unit to bring the performance of the system back to original. When the fan gets blocked up with gunk, mould and dirt it reduces airflow, the reduced air flow reduce the performance, this usually happens after around five to ten years depending on the environment the systems is operating in and how much airborne dirt there is.
