Marine Air Conditioner FAQ
Have boat air conditioning questions before you make your decision? We can help.
Calculate the volume of the space you’ll be cooling (LxWxH). Multiply volume by 14 BTU/cubic foot, then add 1,000 BTUs. Call us for help figuring out marine air conditioner size.
Self-contained marine air conditioners will typically be mounted in a locker or under a bunk, draw in water from a thru-hull connection and combine it with eco-friendly refrigerants that create cool air. This air is then blown throughout the space by a blower motor and fan.
Chilled water marine air conditioners consist of a chiller, located in the engine room, that cools (or heats) fresh water, then pumps it through an insulated piping loop to air handlers located in the living spaces, where the air is cooled (or heated).
Self-contained units are generally the best solution for boats up to 40′, split systems are found on boats up to 80′ in length, and chiller units are used on larger boats and yachts. Contact us for the right solution for your boat
For the more handy boaters out there, you may be able to install your unit on your own. Search for installation / electrical connection support videos from the manufacturer.
A split system has the a/c components split between two separate units (condensing unit and evaporating unit) installed in different locations and connected by insulated copper tubing through which the refrigerant travels.
