Overview
This qualification covers competencies to develop systems; select equipment; and commission, maintain and diagnose faults/malfunctions of refrigeration systems and equipment that apply to commercial food storage and preservation and air conditioning and air distribution equipment and special applications. It includes regulatory requirements for purchasing and handling refrigerants.
Competency development activities in this qualification are subject to regulations directly related to licencing. A relevant contract of training through an apprenticeship or relevant employment may be required to enable the application of the required knowledge and skills to on the job work activities and environments. Refrigerant Handling Licence:
The achievement of the qualification meets the training components for the full national Refrigerant Handling Licence which is required to work on refrigeration and air conditioning equipment that carries the risk of a fluorocarbon refrigerant being emitted while decanting the refrigerant or manufacturing, installing, commissioning, servicing, maintaining or decommissioning refrigeration and air conditioning equipment.
Refrigeration and Air Conditioning Occupational Licence:
Additional and/or other conditions may apply in some jurisdictions subject to regulations related to refrigeration/air conditioning work. Practice in the workplace and during training is also subject to work health and safety (WHS)/occupational health and safety (OHS) regulations.
Electrical Occupation Licence:
The achievement of this qualification with the core restricted electrical units meet the electrical regulatory requirements for related restricted electrical work in most state/territories. This is required to work on electrical installations which are designed to operate at voltages greater than 50 volt (V) alternating current (a.c.) or 120 V direct current (d.c.).

How do apprenticeships and traineeships work?
Apprenticeships and traineeships let you combine hands-on work experience with training. You’ll gain job-ready skills and earn an income while you complete a qualification.
As an apprentice or a trainee, you work with an employer while completing your training. Most of your time is spent learning on the job, with some classroom or online training to support the skills you're developing in the workplace.
For some jobs, you may need to do an apprenticeship or traineeship before you are allowed to work as a qualified tradesperson. For example, you need to do an apprenticeship if you want to work as a licensed electrician.
Find out more about apprenticeships and traineeships.
See more information about the apprenticeship or traineeship you’re interested in pursuing on the Queensland Training Information Service.
How long will this course take?
This course is competency-based training, which means you progress as you demonstrate your skills and knowledge, rather than in a set amount of time.
The duration shown here is an estimate for full-time study based on how long most people take to complete the course. You may finish earlier than other people, or it may take you a bit longer.
If you’ve already completed training or have worked in a relevant area, you could get credits or recognition of prior learning. This can reduce the training you need to complete a qualification, which could reduce the time needed for training.
Duration for apprenticeships and traineeships
Apprenticeships and traineeships take longer than doing the qualification on its own, but you learn valuable hands-on skills.
For some jobs, you may need to do an apprenticeship or traineeship before you are allowed to work as a qualified tradesperson. For example, you need to do an apprenticeship if you want to work as a licensed electrician.
Learn about how courses are delivered
Different courses have different delivery options. Consider your needs when you’re researching courses. Some courses may be delivered entirely online or partially online. Others may be delivered in a classroom.
Some courses, like those delivered through apprenticeships and traineeships, are mostly based in the workplace but with some classroom or online study.
If a certain type of delivery is important to you, talk to your provider before you enrol to make sure they offer that delivery option.
How to reduce the cost of your course
There are lots of ways you can reduce the cost of your course.
- The government could partly or fully cover the cost of your course. See information about financial help and government funding on this page.
- The government also offers funding for some costs related to your course.
- If you’ve already completed training or have worked in a relevant area, you could get a cost credit or recognition of prior learning. This can reduce the training you need to complete a qualification, which could reduce the cost.
Learn about financial help and government funding
The main cost of training is usually the course fees, which vary depending on things like which course and training provider you choose.
You may be able to get your training for free or at a reduced cost, or you could get help with paying for training-related costs. You can also pay for some courses with a VET Student Loan.
Find out more about getting help paying for your training or check if you're eligible.
What are entry requirements?
Some courses have conditions you need to meet before you can enrol in the course. They help make sure you have the right background or skills for the training.
Entry requirements might include a certain education level, skills or knowledge, work status, or experience.
