Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the performance outcomes required to install automotive air conditioning systems in vehicles and machinery for driver and passenger convenience and comfort. It involves preparing for the task, installing and testing the operation of automotive air conditioning systems, and completing workplace processes and documentation.

It applies to those working in the automotive service and repair industry. Air conditioning systems include those being installed in agricultural machinery, heavy commercial vehicles, light vehicles or mobile plant machinery.

Licensing requirements apply to this unit. Users are advised to check with the relevant regulatory authority. An Australian Refrigeration Council (ARCtick) Restricted Refrigerant Handling licence is required for those carrying out this work.
