Troubleshooting, maintenance and system advice for marine air conditioning, chillers and seawater cooling.
Practical, plain-English guides to marine air conditioning, chiller systems and seawater cooling — written for yacht owners, captains, engineers and fleet managers. Each guide explains how the equipment works, what you can safely check yourself, and when a problem needs a marine HVAC engineer.
Start here when something has stopped working. Marine AC not cooling walks through the checks in a sensible order, and seawater pump and cooling-water problems explains the single most common cause of high-pressure trips. If you would rather have an engineer look at it, see marine HVAC troubleshooting and marine air conditioning repair.
Most breakdowns are preventable. The marine air conditioning maintenance checklist sets out what to check weekly, monthly and at each service, and preparing yacht air conditioning for the UAE summer covers the pre-season work that matters most in Gulf conditions. For scheduled servicing, see marine HVAC maintenance and preventive maintenance plans.
Self-contained, split and chilled-water marine AC compared explains the three main system designs and where each fits. Related pages: marine air conditioning installation, marine inverter chiller systems and the inverter chiller brand comparison.
