Application
This unit describes the skills and knowledge required to service air conditioning systems, including heating, ventilation and air conditioning (HVAC) systems, fitted to a range of vehicles and machinery. It involves preparing for the task, carrying out performance testing and correct servicing procedures, performing post-service testing, and completing workplace processes and documentation.
The unit applies to those who work in the automotive service and repair industry. Automotive air conditioners, in addition to HVAC systems, include those in agricultural machinery, heavy commercial vehicles, light vehicles or mobile plant machinery. It does not involve removing, replacing or topping up of refrigerant. The systems used vary depending on the work context.
Licensing requirements apply to this unit. Users are advised to check with relevant regulatory authority. An Australian Refrigeration Council accredited (ARCtick) Refrigerant Handling licence is required for those carrying out this work.
