HPF Errors

By far our most common request is to help customers with High Pressure Fault (HPF or HP on most displays). If you experience one of these, first check and address your water flow, air flow (air filters and evaporator coils). If you find that your refrigerant is low (ie freon), it's usually better to replace the unit than try to find and fix leaks. With self-contained units, leaks are usually symptoms of broader corrosion (kind of like plugging one hole in a dam).

We always have boat ac units in stock and have great relationships with manufacturers like Marinaire, Frigomar and Mabru if we need to order new marine ac units. We can help you determine if a 12v air conditioner marine unit would be best for you to replace your marine air 16000 btu air conditioner.
