The Refrigeration and Air Conditioning Systems Mechanic program will cover the design, installation and service techniques of refrigeration and air conditioning systems in residential and commercial buildings.

Consisting of in-class studies and on-the-job training, the Refrigeration and Air Conditioning Systems Mechanic apprenticeship (trade #313A) will take three to five years to complete and include approximately 8,000 hours with an employer. Because of the included real experience, to be eligible for the Refrigeration and Air Conditioning Systems Mechanic program you must be formally employed as an apprentice, currently working in the trade and released by your employer as a 313A apprentice.

At the conclusion of your apprenticeship, including your experience training, you'll be able to write the exam for your certificate of qualification. Passing this exam will mean you qualify for a certificate of apprenticeship from the Ministry of Labour, Training and Skills Development, and that you are certified in your occupation.
