What they do
Air-conditioning and refrigeration mechanics assemble, install, maintain and repair heating, cooling and refrigeration systems and equipment. They may install ducted air-conditioning in a family home, or 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 WA, air-conditioning and refrigeration mechanics 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
Air-conditioning and refrigeration mechanics 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
Air-conditioning and refrigeration mechanics 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.
