HVAC Engineer / Technician
On a big yacht in the Caribbean or the Red Sea, the air conditioning matters more than almost any other system. If it fails, guests leave and the owner phones the captain. The HVAC engineer owns that plant: chillers, air handlers, fan coils, cold rooms and the controls that tie them together. Most come from a shoreside refrigeration trade and learn the yacht side on board.
The jobWhat fills the day
The core of the job is the chilled water plant. You look after the chillers and compressors, sea water cooling pumps, air handling units, and the fan coils fitted in every cabin and public area. You also run the provision cold rooms, freezers, galley refrigeration, wine stores and ice machines. Expect to spend real time on the building management system, tuning setpoints, tracing faulty sensors and logging refrigerant use for F-Gas records and the planned maintenance system.
With guests aboard you are on call for comfort. A master cabin that is half a degree too warm becomes your top priority, and you fix it quietly, often while the guest is at dinner. You avoid noisy work in guest areas and plan around the interior team's schedule. Between trips and in the yard you strip compressors, clean condensers and heat exchangers, replace filters across dozens of units, and work with contractors such as Heinen & Hopman or Condaria on bigger overhauls.
Captains and chief engineers hire people with a proper trade behind them. A City & Guilds or NVQ Level 3 in refrigeration and air conditioning, an F-Gas certificate and a few years on commercial chillers, cruise ships or data centres is the usual profile. Marine experience helps but is often taught on the job. You will also stand engine room watches and help with general maintenance, so a willingness to learn the wider plant is expected.
Progression goes two ways. Many HVAC engineers take the MCA Y4 route, collect sea time and move into third and second engineer roles, eventually chief. Others stay specialist and become the senior HVAC lead on 120m+ yachts, or move ashore into refit yards and technical management, where people who understand marine climate systems are hard to find. Keep a careful sea service record from day one.
Skills captains look for
- Chilled water systems
- Compressor and chiller overhaul
- Refrigerant handling and recovery
- BMS and control diagnostics
- Cold room and galley refrigeration
- Electrical fault finding
- Planned maintenance records
A day aboardOwner trip, 95m motor yacht, at anchor in the Maldives
Walk the engine room and chiller room, checking pressures, temperatures and sea water flow. Log readings and note anything drifting.
Breakfast in the crew mess and a quick word with the second engineer about the day's jobs.
Clean the sea water strainers on the chiller cooling pumps. Warm water and reef growth here clog them faster than in the Med.
Chief stew reports the VIP cabin is running warm. Find a sticking fan coil valve, swap the actuator while guests are on the beach.
Lunch and an hour off in the cabin.
Check the provision freezers and cold rooms after the morning delivery by supply boat. Defrost the fish room evaporator.
Update the planned maintenance system and refrigerant log. Order replacement filters and a spare actuator through the chief engineer.
Adjust air handler setpoints on the BMS ahead of dinner on the main deck aft, where doors stay open all evening.
Off watch, phone on and kept close in case a guest area alarms overnight.
Pay by yacht sizeMonthly, before tips. Estimates. Bars share one scale.
Pay is usually tax-free with food and accommodation covered. Rotational posts on larger yachts trade a slightly lower monthly figure for long paid leave, and charter yachts add tips shared across all crew. See the Engineer salary guide for figures from live adverts.

Questions crew ask
Do I need yacht experience to get an HVAC job on board?
Usually not. Chief engineers value a solid shoreside refrigeration background over yacht time. You will still need STCW and an ENG1 before any interview, and a short daywork stint in Antibes or Palma helps you understand life on board.
What size of yacht carries a dedicated HVAC engineer?
Mostly 80m and above, with a few 70m yachts that run in hot climates all year. Below that, the second or third engineer covers air conditioning alongside everything else.
Will sea time as an HVAC engineer count towards engineering certificates?
Yes, if you are signed on as part of the engine department and your service is properly recorded. Many use it to start the MCA Y4 route, so check with the chief engineer how your time is logged.
Is the work only air conditioning?
No. You normally also handle provision refrigeration, ice machines, wine stores and ventilation, and you stand engine room watches. Expect to help with general engineering jobs during yard periods.
