Marine AC Refrigerant Leak Repair in Tampa
Frozen Evaporator
4/24/20261 min read
We completed a marine AC repair in Tampa where the system was not cooling properly and the evaporator coil was completely iced over.
The customer reported weak airflow and the unit running constantly.
This is a very common sign of a refrigerant leak in a marine air conditioning system.
🧊 Symptom: Frozen Evaporator Coil
When we inspected the unit, the evaporator coil was covered in ice.
This happens when the system runs with low refrigerant (low freon).
⚠️ What this means:
Reduced pressure inside the system
Evaporator temperature drops below freezing
Moisture freezes on the coil
Airflow becomes restricted
👉 Result: marine AC not cooling and eventually shutting down
🔍 Problem: Refrigerant Leak
Further diagnostics confirmed a refrigerant leak in the system.
Running a marine AC with low refrigerant is not just a performance issue — it can cause serious damage.
⚠️ Why leaks are dangerous:
Compressor can overheat and fail
System loses cooling efficiency
Ice buildup blocks airflow
Long-term damage increases repair cost
👉 Simply “adding freon” without fixing the leak is NOT a solution.
🔧 Repair Process
We performed a complete repair following proper marine HVAC procedures:
✔ Leak detection and identification
✔ Repair of the leaking section
✔ System evacuation (deep vacuum)
✔ Proper recharge with refrigerant
✔ Performance testing (superheat/subcool verification)
🌡️ Why Proper Recharge Matters
After fixing the leak, the system must be charged correctly.
Incorrect charge can lead to:
Poor cooling
High pressure faults
Compressor damage
👉 Marine AC systems require accurate refrigerant levels to operate efficiently.
🧠 Preventive Tip
If you notice:
Ice on the AC unit
Weak cooling
Long run cycles
👉 Stop the system and have it inspected.
Running the system in this condition can lead to expensive repairs.
