Question 1

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

admin admin · Accepted Answer

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.

Question 2

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

admin admin · Accepted Answer

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

Question 3

Why is my marine AC blowing warm air?

admin admin · Accepted Answer

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.

Question 4

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

admin admin · Accepted Answer

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

Question 5

How often should I service my marine air conditioning system?

admin admin · Accepted Answer

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

Question 6

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

admin admin · Accepted Answer

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.

Question 7

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

admin admin · Accepted Answer

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

Question 8

What is reverse cycle heating on a boat?

Fryderyk Florczak · Accepted Answer

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.

Question 9

Why is my reverse cycle heater blowing cold air?

Fryderyk Florczak · Accepted Answer

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.

Question 10

Do you check seawater flow during diagnostics?

Fryderyk Florczak · Accepted Answer

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.

Question 11

Can electrical issues affect reverse cycle heating?

Fryderyk Florczak · Accepted Answer

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.

Question 12

Is reverse cycle heating effective in cold weather?

Fryderyk Florczak · Accepted Answer

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.

Question 13

Do you repair issues found during troubleshooting?

Fryderyk Florczak · Accepted Answer

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

Question 14

Can proper troubleshooting extend the life of my HVAC system?

Fryderyk Florczak · Accepted Answer

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

Question 15

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

Fryderyk Florczak · Accepted Answer

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.

Question 16

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

Fryderyk Florczak · Accepted Answer

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.

Question 17

What are the signs that my HVAC system needs descaling?

Fryderyk Florczak · Accepted Answer

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

Question 18

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

Fryderyk Florczak · Accepted Answer

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.

Question 19

Does descaling help prevent HVAC system failures?

Fryderyk Florczak · Accepted Answer

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

Question 20

Do you inspect other components during HVAC acid flushing?

Fryderyk Florczak · Accepted Answer

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.
