Marine air conditioning in Valencia

Most boats use seawater-cooled units: a pump draws water through a seacock, runs it through the condenser and sends it back overboard. That is why the most common faults are not in the compressor but in the water circuit: dirty strainers, worn pumps, scale and growth in the condenser or a blocked intake.

Larger yachts often run a chilled-water system feeding several fan coils, while smaller boats use self-contained units per cabin. Fridges and freezers have their own circuit and usually run on 12 V, so they depend heavily on the state of the batteries.

Before summer, clean the seawater strainer, check the pump and impeller, descale the condenser with a dedicated product and verify the refrigerant charge. A well-serviced unit cools faster and draws less from the generator or shore power.

In Valencia, look for technicians certified to handle refrigerant gases and experienced with marine brands such as Dometic, Webasto or Climma. Ask whether they keep spares in stock: in peak season, waiting for a part can leave you without cooling for a week.
