What a refrigeration and air-conditioning technician actually does
Refrigeration and air-conditioning techs split between domestic installs, commercial service work and large industrial refrigeration. Domestic installers spend the day fitting split systems on residential walls, brazing pipework, vacuuming and charging refrigerant, and commissioning the unit. Commercial techs cover packaged rooftop plant, chillers and ducted systems in offices, hospitals and shopping centres. Industrial refrigeration techs work in food processing, supermarkets and cold storage on ammonia and large CO2 plants. Hours run 7am to 4pm with occasional after-hours call-outs on critical refrigeration when a cool room is failing. The trade is regulated nationally through the ARCtick refrigeration handling licence, which is mandatory for working with refrigerant. Climate change and the energy transition are pushing the industry into heat pumps, low-GWP refrigerants and natural refrigerant systems.
