Job Description

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.

Key Responsibilities

• 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

Qualifications

• 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 acquire, 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.
• Career development within a growing Integrated Facilities Management company.
