Refrigeration

Workers in this field install and maintain the heating and air-conditioning systems that control the temperature, humidity and total air quality in residential, commercial, industrial and other buildings by precisely following blueprints, design specifications and manufacturers’ instructions.

They need knowledge of electrical components and systems since heating, air-conditioning and refrigeration systems consist of many mechanical, electrical and electronic components such as motors, compressors, pumps, fans, thermostats and switches.

In refrigeration, technicians work with a variety of precision measuring tools to manipulate conditions such as refrigerant pressures and air flow in duct systems. Voltmeters, pressure gauges, manometers and other testing devices are used in analyzing system performance. When servicing equipment, they must use extreme care to conserve, recover and recycle the chlorofluorocarbon (CFC) refrigerants used in the refrigeration and air-conditioning systems.

Main duties

Refrigeration and air conditioning mechanics perform some or all of the following duties:

  • Read and interpret blueprints, drawings or other specifications
  • Measure and lay out reference points for installation
  • Assemble and install refrigeration or air conditioning components such as motors, controls, gauges, valves, circulating pumps, condensers, humidifiers, evaporators and compressors using hand and power tools
  • Measure and cut piping, and connect piping using welding and brazing equipment
  • Install, troubleshoot and overhaul entire heating, ventilation, air handling, refrigeration and air conditioning systems
  • Start-up system and test for leaks using testing devices
  • Recharge system with refrigerant, check and test regulators, calibrate system and perform routine maintenance or servicing
  • Repair and replace parts and components for entire refrigeration, air conditioning, ventilation or heat pump systems
