|Description:||The Heating, Ventilation, Air Conditioning and Refrigeration (HVAC and R) industry designs, builds, maintains, and repairs essential indoor comfort and cooling systems including heating, ventilation, and air conditioning. Refrigeration equipment for supermarkets used for food processing and cold storage facilities and sports facilities such as hockey and curling rinks are also a vital part of the industry.
As a result of the expanding markets for refrigeration and air conditioning and changing technology, a dramatic need exists for qualified personnel both at home and abroad. A refrigeration mechanic fabricates, installs, alters, repairs/services any system used for cooling and/or heating (i.e. heat pumps) in closed systems that contain a refrigerant or brine and thermoelectric cooling. This includes piping, controls, and electrical work. These workers also connect rooftop units to gas and test and balance systems.
