Refrigeration and Air Conditioning Mechanic (Refrigeration Mechanic)

Refrigeration Mechanics make, install, repair and service residential, commercial and industrial cooling and heating systems. Some work in building maintenance - for example, servicing the air conditioning systems in high-rise office buildings. Others specialize in repairing small, portable Refrigeration and freezing units. A Refrigeration Mechanic is designated under the Inter-provincial Red Seal Program as a Refrigeration and Air Conditioning Mechanic. As part of their job, they measure, cut and connect piping using welding and brazing equipment. They recharge systems with refrigerant gases as required. They also connect rooftop units to gas, test and balance systems and connect electrical systems. Refrigeration Mechanics must be able to use and adjust computerized controls, use computer software to calculate loads, and work on large machines. In some cases, they need to prepare work estimates for clients.
