Refrigeration and Air Conditioning Mechanic


Refrigeration and air conditioning mechanics install, maintain, repair and overhaul industrial, commercial and residential refrigeration and air conditioning systems and their component parts.

At installation sites, refrigeration and air conditioning mechanics:

  • work from drawings or verbal instructions to mount or place system components,
  • assemble and install refrigeration or air conditioning systems and components,
  • install and calibrate related controls (including wiring), and
  • start up systems, test lines to detect leaks, and record the readings taken to ensure that the system is functioning satisfactorily.

Maintenance work involves checking all parts of a system, lubricating moving parts and monitoring the refrigerant charge. When there is a malfunction, refrigeration and air conditioning mechanics diagnose the problem and fix the unit by replacing or repairing controls, electric wiring or other parts.

Mechanics also repair heating equipment, troubleshoot gas-fired equipment and calibrate all gas-related controls.

For more information regarding tasks and activities, please review the Trade Regulation.
