Refrigeration Technician (Commercial Cold Rooms)

The hospital building services team in Paarl needs an HVAC technician who knows both the electrical side and the refrigerant side. Bring a calm head on busy days and you'll be fine.

This post is Paarl-based, with most of your time spent at a hospital building services team. The first two weeks are spent shadowing someone experienced.

• Install split units, cassettes and ducted systems, including brazing and vacuum work
• Pressure test with nitrogen, pull a deep vacuum and charge with R410A, R32 or R134a
• Recover refrigerant into cylinders and log every kilogram used
• Replace thermostatic expansion valves and electronic controllers
• Clean coils, replace filters and check drain lines on scheduled services
• Diagnose faulty compressors, fans, contactors and control boards

• Refrigeration and air-conditioning trade test or an NQF 4 occupational certificate
• Brazing, flaring and vacuum skills you can demonstrate
• At least 2 years servicing commercial or residential systems

• Transport refrigeration units on trucks and trailers
• CO2 transcritical refrigeration experience in retail stores

• Company vehicle with a fitted tool rack
• Gauge manifold, vacuum pump and recovery unit issued to you
