Role Details

Preventive Maintenance

• Conduct scheduled preventive maintenance on assigned HVAC equipment.
• Inspect and clean filters, coils, condensate trays, and drainage systems.
• Inspect fans, motors, belts, electrical connections, and mechanical components; measure and record operating parameters.
• Identify early signs of refrigerant leakage, abnormal noise, vibration, or reduced cooling efficiency; report defective components and recommend corrective action.
• Maintain accurate preventive maintenance records.

Corrective Maintenance

• Diagnose air-conditioning breakdowns and cooling-performance problems.
• Repair or replace defective HVAC components within authorized technical scope.
• Investigate water leakage and condensate drainage problems and identify HVAC electrical and mechanical faults.
• Test repaired equipment before returning it to service.
• Escalate complex failures requiring specialist equipment, certification, or manufacturer support.

HVAC System Coverage

• Practical capability is expected with split air-conditioning systems, ducted split systems, package air-conditioning units, common HVAC electrical controls, condensate drainage systems, motors, fans, and related mechanical components.
• Experience with VRF systems and Air Handling Units is highly desirable.

Materials and Equipment

• Identify spare parts and consumables and submit material requirements to the supervisor.
