The Mid-Level Marine HVAC Technician – Installation and Repair is responsible for executing the installation, commissioning, and repair of shipboard HVAC systems including air conditioning, ventilation, and refrigeration systems. The technician works semi-independently to ensure that HVAC equipment and ductwork are installed and functioning according to marine engineering standards and project specifications, while maintaining environmental safety and crew comfort across vessel zones.
Perform the installation, alignment, and fitting of HVAC components such as AHUs, chillers, compressors, ducting, dampers, and grilles on ships and offshore platforms.
Execute ventilation system layout, duct routing, flexible connections, and insulation in accordance with engineering drawings.
Conduct basic testing and commissioning activities such as leak testing, airflow measurement, refrigerant charging, and system startup.
Diagnose and repair faults in HVAC systems including motors, thermostats, sensors, control panels, and valves.
Ensure proper electrical and mechanical connections, mounting, and vibration isolation of HVAC equipment.
Coordinate with electricians and shipfitters during system integration and cable routing.
Support routine servicing tasks such as filter replacement, pressure checks, and component calibration.
Maintain technical documentation of installation progress, repair activities, and part replacements.
Ensure compliance with marine safety and HVAC installation standards, including fire protection requirements around ductwork.
Mentor junior technicians or apprentices during team-based tasks.
Installation Execution and System Setup
– Independently install HVAC systems in accommodation spaces, engine rooms, and hazardous areas.
Hands-On Repair and Diagnostics
– Troubleshoot and repair mechanical and electrical HVAC faults during construction, commissioning, or service.
Marine Environment Adaptation
– Adapt installation methods for shipboard constraints including vibration, corrosion, and space limitations.
Interdisciplinary Coordination
– Work closely with structural, electrical, and piping teams to ensure proper system integration.
Technical diploma or certification in HVAC, Marine Engineering, Mechanical Technology, or related field.
3–6 years of experience in HVAC system installation and repair, preferably in a marine or offshore environment.
Proficient in reading and interpreting HVAC layout drawings, schematics, P&IDs, and ducting plans.
Strong working knowledge of HVAC components including chillers, fans, compressors, thermostats, VFDs, and air distribution systems.
Skilled in using tools and instruments such as manometers, refrigerant gauges, multimeters, and leak detectors.
Familiar with marine HVAC regulations (IMO, SOLAS, ASHRAE) and installation safety codes.
Ability to work in confined spaces, at heights, and offshore/onboard vessels as needed.
Good communication and team coordination skills.
Certification in EPA refrigerant handling, marine HVAC systems, or offshore safety training (BOSIET/STCW).
Experience with HVAC installations on LNG carriers, cruise ships, FPSOs, or naval vessels.
Familiarity with fire dampers, emergency ventilation cutoffs, and integration with fire/gas detection systems.
