Course Description

This is a preparation course for individuals who will be attempting the 313A Certification of Qualifications (C of Q) Examination administered by the Ontario College of Trades (OCOT).

Individuals who are currently enrolled in an apprenticeship program and want a review before writing the C of Q exam are highly recommended to register!

A 313A Refrigeration and Air Conditioning Systems Mechanic license will enable you to work on any cooling and heating-cooling combination systems including geo-exchange systems in residential, industrial, commercial and institutional settings. Specifically, you will be able to plan, lay out, install, start-up, maintain, service, repair, test, verify, commission and decommission refrigeration and AC systems, electronic components and their accessories.

In Ontario, the Refrigeration and Air Conditioning Trade is also a part of the Interprovincial Red Seal Program.

Furthermore, you do not need to have a 313D license before you can attempt the 313A C of Q exam.
