Maintenance Programs That Pay for Themselves
A $400 spring AC service prevents a $2,500 compressor replacement in August. A $375 battery checkup prevents being stranded 10 miles offshore. Scheduled maintenance is the lowest-cost investment on your vessel.

Why This Matters
Marine AC units run in the harshest possible environment — salt water, humidity, and heat. Without seasonal service, salt buildup restricts water flow, coils corrode, and compressors overheat.
Scheduled inspection records seawater flow, strainers, pumps, coils, electrical condition, temperatures, controls, and observed operating condition. Findings determine whether cleaning, service, testing, or repair should be quoted.
Equipment experience includes supported Dometic, Marine Air, Webasto, legacy Cruisair, Mabru, and other marine AC installations. Exact service scope depends on the installed model, documentation, access, tooling, and parts.
All prices are starting estimates. Final quotes are based on vessel inspection, system condition, number of units, and access requirements.
