The Mid-Level HVAC Maintenance Technician is responsible for performing preventive and corrective maintenance on shipboard and offshore HVAC systems, including air conditioning, ventilation, heating, and refrigeration equipment. The role involves diagnosing faults, executing repairs, optimizing performance, and ensuring compliance with marine operational standards and safety protocols. The technician operates semi-independently and supports junior team members while ensuring system reliability in diverse marine environments.
Conduct scheduled preventive maintenance of HVAC systems such as AHUs, chillers, compressors, heat exchangers, ductwork, fans, dampers, and control systems.
Diagnose and repair mechanical and electrical faults in HVAC components including motor drives, control valves, sensors, and thermostats.
Monitor and adjust airflow, refrigerant charge, temperatures, and humidity levels to maintain proper environmental conditions.
Inspect and service ventilation systems for accommodation areas, control rooms, machinery spaces, and hazardous zones.
Assist in the testing and balancing (TAB) of ventilation systems and verify airflow distribution and pressure regulation.
Maintain accurate records of maintenance activities, part replacements, service logs, and system performance reports.
Support emergency repairs and system restarts, especially during drydock periods, equipment upgrades, or post-shutdowns.
Ensure compliance with marine safety codes, environmental standards, and refrigerant handling regulations.
Mentor junior technicians and provide guidance during routine inspections and maintenance activities.
Coordinate with shipboard engineering staff or offshore platform teams for access, planning, and execution of maintenance work.
Technical Fault Diagnosis and Corrective Action
– Independently troubleshoot mechanical and control issues in HVAC equipment and restore system performance.
Preventive Maintenance Compliance
– Ensure regular maintenance is performed as per OEM recommendations and vessel maintenance schedules.
Marine HVAC Operation Standards
– Maintain operational readiness of HVAC systems critical to crew comfort, electronic cooling, and air quality, even in harsh marine conditions.
Team Support and Knowledge Transfer
– Supervise or assist junior technicians while upholding safety and quality workmanship.
