Firsthand chiller assignment · Naples
The owner reports full Condaria chiller service on this Pershing 80, alongside MTU engine and gearbox service. The photo shows refrigeration compressors and piping in the yacht’s engine room; the exact chiller model and work performed on each pictured component are not established by the image alone.
Owner-provided equipment photographs
These equipment-reference images are separate from the documented Pershing assignment. The brand, vessel, service history and work performed cannot be established from the photos alone.

South Florida saltwater doesn't forgive neglect. Here's what we pull out of marine AC strainers.

Actual raw water strainer from a boat in Fort Myers. Barnacles and calcium scale choke water flow, killing cooling performance. A professional flush restores full capacity.
These manufacturer marks identify equipment Accumar evaluates for service, repair, installation, or replacement. They do not imply authorization. Dometic dealer/service status and factory-trained technician support are documented separately on this page.

Flow Marine Systems
TechnicoldSeasonal heat places more demand on marine air-conditioning systems and can expose restricted seawater flow, fouled heat exchangers, weak pumps, and control faults.
Baseline flow, temperature, electrical, drain, and control checks make developing problems easier to identify.
Liveaboards
High annual run time makes seawater-flow checks, filter care, condensate service, electrical inspection, and documented maintenance especially important.
Seasonal Boaters
Systems that sat idle all winter need flushing before first use. Stagnant saltwater accelerates scale — whether your boat's in the water or on the hard.
Charter / Rental
Pre-season inspection helps identify cooling, drainage, airflow, and control issues before a guest or charter turnaround.
If you notice any of these, call to schedule a diagnostic review.
Reduced cooling can involve seawater restriction, heat-exchanger fouling, airflow problems, sensor faults, or refrigerant-circuit issues. Testing identifies the actual cause before parts are replaced.
Short-cycling can involve a safety limit, restricted heat rejection, electrical instability, sensors, controls, or refrigerant conditions. Continued operation may increase equipment stress.
Reduced discharge may indicate a clogged strainer, worn pump or impeller, air leak, fouled condenser, closed valve, or another seawater-circuit restriction.
Odors can originate at filters, drain pans, evaporators, condensate lines, ducting, or surrounding materials. The correct cleaning scope depends on what the inspection finds.
A trip can involve startup components, compressor load, wiring, connections, supply voltage, or protection devices. Stop repeated resets and have the circuit and equipment diagnosed.
