For boat owners enjoying Galveston Bay and nearby waters, a failing air conditioning system is more than an inconvenience—it’s a major compromise to comfort and a threat to your vessel’s interior health.

The Top 3 Reasons Your Marine AC is Underperforming
Before you face another sweltering day on your yacht, let’s look at the most common culprits behind a failing Cruisair or Dometic system:
1. Restricted Seawater Flow (The Most Common Issue)
Marine AC units use raw seawater to cool the refrigerant (heat exchange). Any restriction in this system will cause the unit to overheat and trip the compressor, resulting in warm air and short cycling.
- The Culprit: Clogged sea strainers, barnacles or marine growth inside the condenser coil, or a faulty seawater pump impeller. 
- The Fix: A professional system flush, known as descaling, is often required to chemically remove mineral scale and marine growth from the condenser coil. The seawater pump and all hoses must also be checked and cleared. 
2. Low Refrigerant Levels or Leaks
Refrigerant is the lifeblood of your cooling system. Over time, the salty marine environment can cause pinhole leaks in the copper tubing or fittings.
- The Culprit: A leak in the refrigeration system is causing the pressure to drop. Low refrigerant causes the unit to run constantly without cooling effectively, leading to high energy consumption and eventually a total failure. 
- The Fix: A certified Refrigeration technician must locate the leak, repair it, and recharge the system with the correct type and amount of refrigerant. 
3. Clogged Air Filters and Condensate Issues
If the air flow over the evaporator coil is restricted by a dirty air filter or if the condensate drain is blocked, your unit can freeze up or suffer reduced efficiency.
- The Culprit: Dirty air filters, blocked return vents, or a clogged condensate pan/drain line leading to water pooling inside the unit. 
- The Fix: Regular air filter cleaning/replacement is a user maintenance task, but a professional overhaul includes cleaning the evaporator coil and ensuring the condensate pump and drain lines are clear and working correctly to prevent mold and water damage. 
When to Overhaul Your System—Not Just Patch It
If your Cruisair or Dometic unit is more than 10 years old, or if you find yourself calling for Marine AC Repair multiple times a season, a full system overhaul or replacement is often the most cost-effective solution in the long run.
A comprehensive Yacht Service overhaul from our team near Baytown includes:
- Complete Descaling: A chemical flush of the condenser to restore cooling efficiency to factory standards. 
- Thorough Inspection: Checking the compressor, fan motor, all wiring, circuit boards, and the thermostat/control panel (like the popular SMXir and Passport models). 
- Preventative Maintenance: Replacing worn-out components, such as the seawater pump impeller or a failing fan motor, before they cause a breakdown.
