HVAC TECHNICIAN — DAIKIN VRV, AHU & CHILLERS

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). The role requires a technician confident working independently on routine PPM while escalating complex faults appropriately, in a live, 24/7, high-footfall environment.

•Carry out scheduled PPM (monthly/quarterly) on VRV/VRF outdoor and indoor units, AHUs, and chiller plant, per OEM (Daikin) service intervals.

•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.

Requirements

•OND/HND or Trade Certificate in Mechanical/Refrigeration & Air-Conditioning Engineering, or a related technical discipline.

•Minimum 3–6 years' hands-on experience maintaining commercial HVAC systems, with direct working knowledge of Daikin VRV/VRF, AHUs, and chiller plant.

•Working knowledge of BMS-monitored environments; comfortable interpreting BMS alarms and trend data.

•Manufacturer-recognised technical training/certification (Daikin or equivalent) is an advantage.

•F-Gas/refrigerant handling certification, or willingness to obtain, is an advantage.

•Comfortable working with a CMMS/CAFM system for logging maintenance activity (training provided if not previously used).

•Strong fault-finding and diagnostic skills, with a methodical, safety-first approach to work.

•Willingness to work shifts, be on standby/on-call, and respond to emergency call-outs outside normal hours.

•Physically fit and able to work at height and in plant-room/industrial environments.

Benefits

•Competitive salary commensurate with experience.

•Structured PPM environment with clear procedures, tools, and CMMS support.

•Opportunity to work on a large-scale, high-profile facility with a modern, BMS-managed HVAC installation.
