AC Technician - VRV/VRF & Conventional System

Key Responsibilities:

• Maintenance and Servicing:

• Perform routine and preventive maintenance of VRV/VRF systems, split units, and

package units and also refrigeration equipment (freezers, fridge, coolers, etc.).

• Clean filters, check refrigerant levels, inspect electrical components, and calibrate

thermostats and controls.

• Ensure smooth functioning of indoor and outdoor VRF units by regularly inspecting

compressor performance, fan operation, and inverter functions.

• Perform leak detection, vacuuming, refrigerant recovery and recharging in

accordance with safety and environmental standards.

• Troubleshooting and Repair:

• Diagnose and troubleshoot faults in VRV/VRF systems including communication

failures, sensor malfunctions, and electronic expansion valve issues.

• Interpret VRV/VRF system error codes using service tools and control panels to

pinpoint system malfunctions.

• Repair or replace defective components including compressors, fan motors, PCBs,

sensors, and control boards.

• Analyze system operating parameters such as pressure, temperature, and current to

identify inefficiencies or failure trends.

• Coordinate with OEM technical support or manuals when dealing with complex

VRV/VRF issues.

• Installation Support:

• Assist in installation and commissioning of VRF/VRV systems and standard units as

per drawings and manufacturer specifications.

• Perform piping, insulation, vacuuming, and gas charging for new installations.

• Install related electrical works like wiring and DP switch etc., as per site conditions

• System Monitoring and Testing:

• Use diagnostic tools (e.g., manifold gauges, clamp meters, VRF controllers) to assess

system health.

• Monitor and record system pressures, temperatures, and airflow to ensure optimal

performance.

• Coordination and Reporting:

• Coordinate with supervisors and engineers for scheduled maintenance and urgent

repair works.

• Experience:

• Minimum 4–6 years hands-on experience in servicing VRV/VRF systems (preferably

Daikin, LG, or Mitsubishi) and conventional AC units.

• Technical Skills:

• Strong diagnostic and problem-solving skills specific to VRF technology.

• Familiarity with wiring diagrams, control systems, and remote monitoring tools.

• Knowledge of refrigerant types (R410A, R32) and handling procedures.

• Experience in maintenance and repairing of refrigeration units like refrigerators,

freezers, ice makers, water coolers, etc.
