FAQ
What BTU marine AC unit do I need for my boat?
Sizing generally depends on cabin volume, insulation, and climate, with many boats requiring roughly 150 to 250 BTUs per square foot of cabin space.
What’s the difference between a self-contained and split marine AC system?
A self-contained unit packages the compressor, condenser, and evaporator into one compact system, while a split system separates the compressor and condenser from the cabin-side air handler for quieter operation.
Can I run a marine air conditioner off my boat’s batteries?
Most standard marine AC units require too much power for typical battery setups and need shore power or a generator, though some 12V models are designed to run efficiently directly from batteries.
