Dometic marine AC keeps the cabin comfortable at the dock and underway. Size the BTUs to your space, plan the seawater cooling, and match the controls and ducting. A cool cabin makes a boat livable in summer, and Dometic builds the marine air conditioning to do it, from compact self contained units to larger systems, plus the controls, pumps, and parts. Marine AC is seawater cooled and very different from a home unit, so choosing right comes down to sizing the BTUs to your space, planning the cooling water, and matching the voltage and controls.

Dometic marine AC keeps the cabin comfortable at the dock and underway. Size the BTUs to your space, plan the seawater cooling, and match the controls and ducting.
A cool cabin makes a boat livable in summer, and Dometic builds the marine air conditioning to do it, from compact self contained units to larger systems, plus the controls, pumps, and parts. Marine AC is seawater cooled and very different from a home unit, so choosing right comes down to sizing the BTUs to your space, planning the cooling water, and matching the voltage and controls.
Air conditioners are rated in BTUs, and you size them to the volume of the space and how much sun and insulation it has. An undersized unit runs constantly and never catches up, while an oversized one short cycles and leaves the air clammy. Measure the cabin volume and account for hatches, windows, and sun exposure, then match the BTU rating, going up for a sunny, poorly insulated cabin. Take time to calculate the total area including any connected spaces that will share the cooled air.
Self contained units package the compressor, coil, and blower in one box that mounts low in the boat and ducts cool air to the cabin, which is the common, straightforward choice. Larger boats may use chilled water or split systems that serve multiple zones from a central unit. Match the system type to your boat size and how many areas you want to cool. Consider future expansion when deciding on a single zone or multi zone setup.
Marine AC rejects heat to seawater, so it needs a dedicated cooling pump, a thru hull intake with a seacock and strainer, and an overboard discharge. Plan that plumbing as part of the install, and keep the strainer clean, since a blocked raw water flow shuts the AC down fast. The pump has to be sized to the unit flow rate. Route the intake low and away from other discharges to avoid warm water recirculation.
Marine AC runs on AC power, commonly 115V or 230V, so confirm your boat shore power and generator can carry the load. Modern Dometic units use digital controls and thermostats for set temperature and fan speed, and some tie into onboard monitoring. Match the control to the unit and verify that the wiring and breakers are rated for the startup current draw.
Pumps, controls, ceiling assemblies, and seals are available to service an existing Dometic system rather than replacing the whole unit. Match the part to your model and keep the strainer and pump maintained for reliable cooling. Regular inspection of hoses and electrical connections prevents most failures during the season.
Not sure which Dometic AC fits your boat. Tell our techs your cabin size, power, and how many zones you want to cool, and we will match the BTUs, system type, pump, and controls so the cabin stays comfortable. Proper installation and routine care will give years of quiet, dependable performance on the water.
