This image has been updated and the title "Air Conditioning & Refrigeration Mechanic" has been replaced with Airconditioning and Refrigeration Technician since 17 December 2024. The above image is therefore incorrect but OTJ left it in to show the pathways. It will be changed when ARC shows a new image.

Airconditioning & Refrigeration Technicians assemble, install, test, service and repair industrial, commercial and domestic heating, air conditioning and refrigeration systems in homes, shops, factories, office buildings, hospitals, and supermarkets.

Airconditioning & Refrigeration Technicians install, maintain and repair heating, cooling and refrigeration systems and equipment. They may install ducted air-conditioning in a family home, or Future Growth Strong build large walk-in refrigeration units for businesses needing mass food storage. They bolt and build units into buildings with brackets, piping, gas and water lines, cabling and wires. Following pre-set specifications, they use motors, pumps, filters, switches and gauges to put together the heating or cooling system that is required for the job.

In Australia, Airconditioning & Refrigeration Technicians are mainly employed by installation service maintenance and manufacturing firms that service shops, hotels and factories. Others can find work with firms that specialise in cold storage, food treatment plants and refrigeration on ships.

Working conditions

Airconditioning & Refrigeration Technicians work wherever they are required to install heating and cooling systems. These locations can be indoors or outdoors, at factories, industrial plants, restaurants, licensed premises, offices, private dwellings or construction sites. Their work environments can often be cramped, noisy, dirty or humid. Sometimes, they may have to work at heights. They usually work normal business hours, but may be required to be on call, day or night, to conduct emergency repairs.

Tools and technologies

Airconditioning & Refrigeration Technicians use drills, spanners, screwdrivers, hammers, welding equipment, pumps and grinders to install and repair heating and cooling units. Since their working environment can sometimes be hazardous, they are often required to wear personal protective equipment (PPE), which may include bright and reflective safety gear, hard hats, earmuffs, goggles, masks and enclosed steel-capped boots.

Education and training/entrance requirements

To become an Airconditioning & Refrigeration Technician, you usually need to complete an apprenticeship. The air conditioning and refrigeration mechanic – engineering trade apprenticeship usually takes 48 months to complete and is available as a school-based apprenticeship.

To work as an Airconditioning & Refrigeration Technician in Australia, you must obtain a restricted electrical licence. Contact the EnergySafety Division of the Department of Commerce (in each State) for more information.

To work with refrigerant chemicals in Australia, you must apply for a refrigerant handling licence from the Australian Refrigeration Council (ARC).

Apprenticeships and traineeships

As an apprentice or trainee, you enter into a formal training contract with an employer. You spend most of your time working and learning practical skills on the job and you spend some time undertaking structured training with a registered training provider of your choice. They will assess your skills and when you are competent in all areas, you will be awarded a nationally recognised qualification.

If you are still at school you can access an apprenticeship through your school. You generally start your school based apprenticeship by attending school three days a week, spending one day at a registered training organisation and one day at work. Talk to your school's VET Co-ordinator to start your training now through VET in Schools. If you get a full-time apprenticeship you can apply to leave school before reaching the school leaving age.

If you are no longer at school you can apply for an apprenticeship or traineeship and get paid while you learn and work.

Air ducts have more germs than a chicken coop.

EPA claims indoor air has been found to be up to 70% more polluted than outdoor air.

A build up of 10.668mm [0.42 inches] of dirt on a heating or cooling coil can result in a decrease in efficiency of 21%.

Operates and maintains stationary engines, boilers, refrigeration and air conditioning systems, and associated mechanical plants. Boiler operators control and maintain boilers, airconditioning and heating equipment in industrial plants.

Boiler or engine operators operate and maintain stationary boilers and engines, and associated mechanical plant equipment. They maintain boilers that are used to supply heat or steam for power that operates machines. They may light the fuel used in the boiler and control the flow of fuel and water into the boiler.

They monitor the control panel and regulate temperature, pressure, draft and other operational parameters. They also observe the boiler and secondary units to check for any faults, and perform minor repairs as well as required maintenance. They may also need to treat the water used in the boiler with special chemicals.

Registration or licensing is required.
