This pre-employment assessment helps Air Control evaluate potential refrigeration mechanic hires across the practical knowledge and workplace behaviours required on Australian HVAC and refrigeration sites. It assesses site safety, PPE, hazard reporting, electrical isolation, fault-finding, refrigeration diagnostics, installation testing, documentation, communication, work ethic, apprentice supervision, and relevant compliance requirements. Candidates are tested on realistic scenarios, including leak response, system faults, lockout/tagout, safe refrigerant handling, and professional conduct. The assessment is designed to identify applicants who can work safely, diagnose methodically, communicate clearly, and support reliable project delivery.
