Job Responsibility:

Perform diagnostics and root cause analysis on multi-zone VRV/VRF systems (Daikin, Mitsubishi, LG, etc.)
Conduct system performance verification, including checking inverter compressor operation, EEV functionality, and pressure/temperature relationships
Accurately interpret wiring diagrams and perform low/high voltage troubleshooting
Commission new VRV systems and verify factory start-up procedures are completed to spec
Utilize manufacturer-specific tools and software (Daikin Service Checker, Mitsubishi Maintenance Tool, LG LGMV, etc.)
Analyze operational data from service tools to identify abnormal operation, refrigerant imbalance, or control logic failures
Execute refrigerant circuit service work, including leak detection, evacuation, charging by weight/subcool/superheat, and component replacement
Interpret and follow service bulletins, technical manuals, and engineering documentation
Document detailed service reports with recommendations and corrective actions taken
Collaborate with technical leads and project managers to resolve ongoing or complex issues in the field

Requirements:

Deep understanding of VRV/VRF operation and architecture (heat recovery, heat pump, branch selector boxes, control logic)
Proficient with manufacturer-specific diagnostic software and tools
Strong electrical troubleshooting skills (including 3-phase, inverter boards, sensors, and communication wiring)
Knowledge of pressure/temperature enthalpy relationships and system balancing
Understanding of control strategies for both cooling/heating and defrost sequences
Ability to identify software vs. hardware failures in the field
Familiarity with refrigerant flow control and piping configuration (including oil return and elevation considerations)
Experience with indoor and outdoor board/component replacement
Comfort working independently on active systems with high expectations for performance

Nice to have:

3+ years of experience servicing VRV/VRF systems in commercial environments
Factory training or certification from major manufacturers (Daikin, Mitsubishi, LG, etc.)
Proven ability to interpret and analyze service tool data
Experience supporting building engineers or facilities managers with system operation guidance
Experience with commissioning and re-commissioning VRV systems post-install
Familiarity with BACnet/Modbus integration or BMS system interaction
