Preventive Marine Service

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.

A $395 spring service prevents a $2,500+ compressor replacement in August. We see it every summer — boats that skipped service calling for emergency repairs when every tech in SWFL is booked.

We service Dometic, Marine Air, Webasto, Cruisair, Mabru, and all major marine AC brands. Factory-trained technicians, not general handymen.

All prices are starting estimates. Final quotes are based on vessel inspection, system condition, number of units, and access requirements.
