The HVAC Technician will maintain, service, and repair a large-scale commercial HVAC system comprising Daikin VRV/VRF systems, air handling units (AHUs), and chillers, all managed through a Building Management System (BMS).

Clean/replace filters, inspect coils and condensate systems, and check refrigerant lines for leaks across all zones.
Diagnose and repair mechanical, electrical, and refrigerant-circuit faults on VRV systems, AHUs, and chillers.
Monitor and respond to BMS alarms and trends; support fault-finding using BMS data.
Check thermostat calibration, compressor amperage, and condenser performance; carry out deep cleans on schedule.
Support chiller-specific tasks: water treatment checks, pump and cooling-tower inspection, and load monitoring.
Maintain accurate maintenance logs, service records, and defect reports using the facility's CMMS/CAFM platform.
Respond promptly to HVAC-related emergency call-outs, including out-of-hours where required.
Follow safe isolation and permit-to-work procedures at all times; no bypassing of safety systems under any circumstance.
Liaise with the HVAC Lead/Chief Engineer on parts requisition, defect escalation, and PPM scheduling.
