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

  • may install, maintain and repair equipment in refrigerated trucks used to transport food or medical supplies
  • may prepare work estimates for clients, as well as completing work orders, inspection sheets and other paperwork

Work environment

The majority of refrigeration and air conditioning mechanics work 40 hours per week. However, overtime and on-call work is commonly required to complete a project or to repair malfunctioning critical equipment (e.g., freezers containing perishable items) immediately.

Refrigeration and air conditioning mechanics often work indoors. They may work in buildings under construction or in warehouses, office towers, hospitals, schools or stores. Outside work may also be required, so workers may be exposed to various weather conditions.

Work in awkward or cramped positions and at heights is common. Hazards may include injuries from handling heavy equipment or from electrical shock. Safety procedures are followed, particularly when handling potentially harmful refrigerants.

Insights from industry

The majority of job openings will come from the need to replace those who retire.

The Construction industry, the largest employer of refrigeration and air conditioning mechanics, has been experiencing a very strong demand for workers in both residential and non-residential sectors. Government funding for capital projects could also be an important source of construction work. Industry sources report that there is an over-abundance of people trying to enter the industry with only pre-apprenticeship training or no prior experience at all.

Renewed concern for energy conservation should result in the development of new energy-saving heating and air conditioning systems. An emphasis on better energy management and environmentally safe refrigerants will likely lead to older systems in existing homes and buildings being replaced with more efficient systems. These activities will create a demand for refrigeration and air conditioning services.

The increasing use of technology in refrigeration and air conditioning, such as sophisticated control systems, as well as new forms of refrigerants, requires mechanics to be up to date with the latest systems and developments. Workers with current technological knowledge will have more work opportunities.
