Do you repair and install marine air conditioning systems on all boat types?

Yes — we service and install marine AC systems on sailboats, cruisers, sportfishers, trawlers, and luxury yachts. We work with all major brands including Dometic, Webasto, and MarinAire.

Can you come to my slip if my AC stops cooling?

Absolutely — we offer mobile marine AC diagnostics and repair at your slip in Marina del Rey, Long Beach, San Pedro, and surrounding marinas.

Why is my marine AC blowing warm air?

Warm air usually indicates low refrigerant, a clogged seawater strainer, bad pump, restricted coils, or electrical issues. We diagnose the problem and restore cooling performance.

Can you install a new AC unit if my old one fails?

Yes — we handle complete AC replacements, including unit sizing, ducting, pump installation, wiring, seawater plumbing, and digital thermostat upgrades.

How often should I service my marine air conditioning system?

We recommend servicing at least once per season, which includes flushing lines, cleaning coils, checking pumps, and inspecting electrical connections to ensure reliable operation.

Can you add AC to a boat that never had it before?

Yes — we design custom retrofit AC installations, adding ductwork, seawater pumps, return vents, and power connections even on boats that didn’t come with factory air conditioning.

o you work with chilled-water systems and multi-zone AC setups?

Yes — we service and install multi-zone AC systems, chilled-water units, and advanced climate control setups for larger yachts and commercial vessels.

What is reverse cycle heating on a boat?

Reverse cycle heating uses your marine air conditioning system to produce heat by reversing the refrigerant flow. It’s an efficient way to heat cabins in cooler weather without separate heaters.

Why is my reverse cycle heater blowing cold air?

This is often caused by low refrigerant, poor seawater flow, faulty sensors, or control board issues. Troubleshooting identifies the exact cause so the system can heat properly again.

Do you check seawater flow during diagnostics?

Yes, we inspect raw water pumps, strainers, hoses, and discharge flow. Restricted water flow is one of the most common reasons reverse cycle heating fails to operate efficiently.

Can electrical issues affect reverse cycle heating?

Absolutely. Faulty relays, control panels, thermostats, or wiring can prevent the system from switching into heating mode. Electrical testing is part of our troubleshooting process.

Is reverse cycle heating effective in cold weather?

Reverse cycle systems work best in mild to moderate cold conditions. When seawater temperatures drop too low, efficiency decreases, which is why proper diagnostics and system setup are important.

Do you repair issues found during troubleshooting?

Yes, once the issue is identified we can repair or replace pumps, sensors, control boards, or refrigerant components to restore reliable heating performance.

Can proper troubleshooting extend the life of my HVAC system?

Definitely. Early diagnosis prevents compressor strain, electrical damage, and cooling system failures, helping your marine HVAC system last longer and operate more efficiently.

Why does my marine air conditioning system lose cooling efficiency over time?

Reduced cooling efficiency is often caused by mineral scale, salt buildup, and marine growth inside the HVAC heat exchanger. Descaling and acid flushing remove these deposits and restore proper heat transfer.

What is acid flushing and is it safe for my marine HVAC system?

Acid flushing uses marine-approved solutions to dissolve scale and buildup inside the cooling circuit. When done correctly, it is completely safe and prevents corrosion, overheating, and compressor strain.

What are the signs that my HVAC system needs descaling?

Common signs include weak airflow cooling, frequent high-pressure shutdowns, warmer cabin temperatures, or reduced water flow from the discharge outlet.

How often should marine HVAC descaling and acid flushing be performed?

For boats operating in saltwater, we recommend descaling every 12 months or every 250–300 operating hours. High-use systems may require more frequent service.

Does descaling help prevent HVAC system failures?

Yes. Removing internal buildup improves water flow, reduces operating pressure, and protects major components like compressors, pumps, and heat exchangers from premature failure.

Do you inspect other components during HVAC acid flushing?

Absolutely. We inspect raw water pumps, hoses, strainers, discharge flow, and system pressures to ensure the entire HVAC cooling circuit is operating correctly after flushing.

What does a marine autopilot system do?

1 answer

Fryderyk Florczak answers Dec 21, 2025

A marine autopilot automatically maintains your boat’s heading or course, reducing steering fatigue and improving navigation accuracy. It’s especially useful for long trips, offshore runs, and precise course holding.

#1297 Oliver, boat owner in Newport Beach asks asks Dec 21, 2025

Can a new marine AC system improve onboard comfort and resale value?

1 answer

Fryderyk Florczak answers Dec 21, 2025

Absolutely. A properly installed and upgraded marine AC system improves cabin comfort, reduces humidity, protects interior finishes, and can significantly increase your boat’s resale value.

#1295 Samantha, yacht owner in Long Beach asks asks Dec 21, 2025

Do you test the system after installation or upgrade?

1 answer

Fryderyk Florczak answers Dec 21, 2025

Yes, we perform full operational testing, including cooling output, water flow, electrical load, and thermostat accuracy to ensure the system runs safely and efficiently.

#1292 Danielle, sailboat owner in Long Beach asks asks Dec 21, 2025

Does a new marine AC system increase power consumption?

1 answer

Fryderyk Florczak answers Dec 21, 2025

Modern marine AC systems are far more energy-efficient than older units. Upgrading often reduces overall power usage while providing better cooling and quieter operation.

#1290 Tyler, cruiser owner in Newport Beach asks asks Dec 21, 2025

How do you determine the correct AC size for my boat?

1 answer

Fryderyk Florczak answers Dec 21, 2025

We calculate cooling requirements based on cabin volume, insulation, window exposure, engine heat, and usage patterns. Proper sizing prevents short cycling, excessive power draw, and uneven cooling.

#1288 Melissa, motorboat owner in Long Beach asks asks Dec 21, 2025

Can I upgrade an older marine AC system instead of replacing it completely?

1 answer

Fryderyk Florczak answers Dec 21, 2025

In many cases, yes. We can upgrade components such as compressors, pumps, digital controls, or air handlers to improve efficiency and performance without replacing the entire system.
