Chiller Technician (Hospitals & Data Centres)

The hospital building services team in Soweto needs an HVAC technician who knows both the electrical side and the refrigerant side. If you turn up on time and finish what you start, you'll fit in quickly.

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

• Service cold rooms, display fridges and freezers on planned maintenance routes

• Commission new systems and show the client how to use the controls
• Pressure test with nitrogen, pull a deep vacuum and charge with R410A, R32 or R134a
• Diagnose faulty compressors, fans, contactors and control boards
• Replace thermostatic expansion valves and electronic controllers
• Complete service reports on a tablet and have the site manager sign them

• Comfortable on roofs and ladders in summer heat
• Brazing, flaring and vacuum skills you can demonstrate
• Code 08 driver's licence, since the job is mostly on the road
• At least 2 years servicing commercial or residential systems

• Building management system alarm handling
• CO2 transcritical refrigeration experience in retail stores

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