Boat Air Conditioner Leak Observation Log

Water near an air conditioner does not prove that the drain is the cause. Moisture may come from condensate, condensation on a cold surface, another onboard leak or water entering from outside. Record the location and timing before dismantling anything. If water is near electrical equipment or an active leak is suspected, stop using affected equipment and arrange qualified assistance.

Locating Water from a Boat Air Conditioner

Dry accessible surfaces and observe where moisture returns, only where it is safe to do so. Note whether the system was running, whether it rained and whether the boat was recently washed. Photograph the earliest visible wet point rather than only the puddle below it. Water can travel along a hose or joinery before it becomes visible, so the lowest point is not necessarily the source.

Comparing Leaks During Cooling, Shutdown and Rain

Keep a short log of mode, temperature setting and the time until moisture appears. Note whether doors and hatches were open. Ask the technician to assess drain routing, insulation and surrounding equipment as appropriate. Avoid pushing tools into drains, using chemicals or disconnecting hoses without the model-specific service instructions; an improvised fix may damage a component or conceal the original fault.

Checking for Leaks After Air Conditioning Service

Ask what caused the moisture and what was changed. Run the system under the conditions which previously produced the problem and inspect accessible areas again. Keep photographs and the service note with the maintenance record. Check any affected timber or fabrics as well as the machine itself, because drying the equipment does not necessarily dry the surrounding cabin.

Boat Air Conditioner Leak Recording Checklist

• Record weather, operating mode and first visible wet point.
• Keep water away from live electrical equipment.
• Ask for the cause and corrective work in the service record.
