Marine HVAC Maintenance & Coil Cleaning
Saltwater is brutal on marine AC. Without annual maintenance, seawater coils scale up, pumps lose flow, and compressors fail years early. Our marine maintenance plan keeps your vessel cool and protects the equipment investment.

FAQ
Marine AC Maintenance Questions, Answered
How often should marine AC be serviced?+
Annually at minimum. Boats run year-round in Florida, and saltwater scaling builds fast — semi-annual is recommended for liveaboards and charter vessels.
What is Barnacle Buster?+
A non-corrosive marine descaler we circulate through raw-water loops to dissolve scale and biofouling without damaging cupronickel or rubber components.
Will neglected maintenance void my warranty?+
Most marine HVAC warranties require documented annual maintenance — our written service log keeps you compliant.
