When you’re cruising the waters of Palm Beach, comfort matters. That means having a marine A/C system that works flawlessly, no matter how high the temps climb. At Coastal Air Systems Marine, we specialize in keeping yacht owners cool with expert mobile marine air conditioning service-delivered right to your dock, marina, or boatyard.
Why Marine A/C Systems Need Experts
Marine air conditioning isn’t just a scaled-down version of what you find in homes. It’s an entirely different beast that lives in a far harsher environment.
Marine Environment Challenges
Salt air, moisture, vibration, and limited airflow create constant stress on marine A/C components. Over time, even the best systems can clog, corrode, or break down without warning.
Marine vs. Residential A/C
Unlike residential systems, marine HVAC setups often include raw water cooling, limited ventilation, tight compartments, and multiple zone controls-all of which require specialized knowledge to service and repair.
Common Problems on Yachts
- Poor cooling performance
- Refrigerant leaks
- Raw water pump failures
- Faulty chillers or split units
- Mold and mildew buildup in ducts
- Electrical or control panel issues
Tech Tip: “One of the biggest mistakes we see? Letting clogged strainers or poor water flow cook your compressor. We diagnose water flow issues fast-before damage spreads.”
When to Call for A/C Service
Not sure if your A/C needs attention? Here’s a quick checklist:
Signs It’s Time to Call Us:
- Cabin feels humid or isn’t cooling properly
- Musty or moldy smells from vents
- System cycles on and off frequently
- Water leaking near the A/C unit
- Display errors or failure to start
- Strange noises from the pump or blower
Urgent Issues:
- Total A/C failure
- Tripped breakers
- Visible water leaks or floods
- Burning smells
Manageable but Worth Checking:
- Reduced cooling efficiency
Warm air at startup - Noticeable noise increase
Don’t let a small issue grow into a weekend-ruining problem.
