“My highest recommendations for Devon and the Maritime Air team — thorough, honest, and on time. They explained everything in plain language and didn't push any unnecessary upsells.”

New Marine AC Installation & Replacement
A correctly sized and properly installed marine AC will run quietly for a decade. The wrong size, the wrong electrical, or a sloppy seawater loop will haunt the boat forever. We size, source, install, and commission marine AC the right way.

FAQ
Marine AC Installation Questions, Answered
How long does a marine AC install take?+
A like-for-like self-contained swap is usually a single day. A new chilled-water system or full retrofit is typically a multi-day yard project.
Can you install at the dock?+
Most self-contained swaps and pump replacements are dockside. Major chilled-water or new-build work usually happens in the yard.
What affects marine AC installation cost?+
Equipment size and brand, number of zones, condition of existing electrical and seawater plumbing, joinery access, and whether the vessel is in the water or in the yard. We quote in writing after a site visit.
