Air conditioning and refrigeration mechanics keep Australia cool, comfortable and running. From split systems in homes to the massive chillers in shopping centres, cold rooms in supermarkets and refrigerated transport moving food across the country, these systems need skilled people to install, service and repair them. If you like problem-solving, working with your hands and understanding how things work, an air conditioning and refrigeration (AC&R) apprenticeship is a solid path into a well-paid, in-demand trade.
This guide walks you through what the apprenticeship actually involves, what you'll earn, how long it takes and the practical steps to get started in Australia.
What the work involves
AC&R is a broad trade, and no two days look the same. Depending on your employer you might work in domestic and commercial air conditioning, industrial refrigeration, or a bit of everything.
Typical tasks include:
- Installing split systems, ducted air conditioning and packaged units
- Servicing and fault-finding on cooling and heating systems
- Working on commercial refrigeration like cool rooms, freezers and display cabinets
- Brazing copper pipework and pressure-testing systems
- Recovering, charging and handling refrigerant gases safely
- Reading wiring diagrams and doing basic electrical work on units
- Preventative maintenance to stop breakdowns before they happen
You'll work on rooftops, in ceiling spaces, in plant rooms and out in the weather. It's physical, and you'll use your brain constantly — diagnosing why a system isn't performing is a big part of the job.
Qualification and training
Most people train through the Certificate III in Air Conditioning and Refrigeration (UEE32211 or its current equivalent). It's a dual-trade style qualification that includes electrical competencies, because so much AC&R work involves wiring and controls.
Your training is split two ways:
- On the job: the bulk of your learning happens at work, under a qualified tradesperson.
- Off the job: you attend TAFE or a registered training organisation (RTO) in blocks or one day a week to cover the theory and practical assessments.
A key extra is the Refrigerant Handling Licence issued by the Australian Refrigeration Council (ARC). By law you can't buy or handle refrigerant gases without it, so getting licensed is essential for real-world work. You'll also usually need a White Card to work on construction sites, and often a driver's licence for getting to jobs.
How long it takes
An AC&R apprenticeship usually runs around four years full-time. The exact length depends on your state, your training contract and how quickly you progress through the units — apprenticeships are increasingly competency-based, so if you pick things up fast you may finish sooner.
Your apprenticeship is formalised through a training contract registered with your state or territory training authority. There's a probation period at the start, after which the arrangement becomes ongoing. For more detail on how this works, read Apprenticeship Contracts and Probation Explained.
What you'll get paid
Apprentice wages are set by the relevant modern award — for AC&R that's usually the Electrical, Electronic and Communications Contracting Award. Your pay is a percentage of the qualified tradesperson rate and steps up each year as you progress.
On top of your base rate you may be entitled to:
- A tool allowance
- Travel and fares allowances for getting to sites
- Overtime and penalty rates
- Superannuation paid on top of your wage
Rather than quote figures that go out of date, use the in-app Wage Calculator to estimate your pay, and check the Apprentice Pay Guide and Allowances and Overtime Explained. The Fair Work Ombudsman is the official source if you ever need to check what you're owed.
How to get started
You don't need a specific score to start — attitude, reliability and a genuine interest in the trade matter most. Here's the practical path:
- Step 1: Finish Year 10 at minimum (many employers prefer Year 12), and do well in maths and science if you can — this trade uses both.
- Step 2: Consider a pre-apprenticeship course to build basic skills and show employers you're serious. See Pre-Apprenticeship Courses: Are They Worth It?.
- Step 3: Get your White Card and, if you can, a driver's licence.
- Step 4: Apply for apprenticeship vacancies. You can browse apprenticeship jobs and create a free profile to get in front of employers.
- Step 5: Nail the interview — brush up with our interview tips and How to Practise for an Apprenticeship Interview.
Another option is signing up with a group training organisation (GTO), which employs you and places you with host businesses. Learn how that works in How Group Training Organisations Work.
Skills and traits that help
The best AC&R apprentices tend to share a few things:
- Comfortable with heights and tight spaces
- Methodical and patient with fault-finding
- Good with hand tools and happy to learn new equipment
- Reliable — turning up on time, every day, matters more than you think. See Reliability Beats Talent.
- Decent communication skills, because you'll deal with customers on service calls

Where it can lead
Once you qualify, you're a licensed AC&R mechanic with strong job security. The trade opens plenty of doors:
- Specialising in commercial or industrial refrigeration
- Moving into building services, energy efficiency or HVAC design
- Becoming a leading hand or supervisor — see Becoming a Leading Hand
- Getting your contractor licence and starting your own business
Because heating and cooling are everywhere, qualified mechanics are needed in every city and region across Australia, and skills transfer well internationally too.
