AC in 2006 FV 270 gradually has quit cooling.

The AC in my 2006 FV 270 gradually has quit cooling. I have back flushed the cooling lines with a mild solution of muriatic acid and this didn't help. I would like to clean the unit but access to it is very limited via the aft berth. Is there any other access to the AC unit. The water flow output for the circulation pump seems comparable to other boats. Suggestions.

If the water circulation is fine, I'd think it's something to do with the freon levels... because that's usually the case with regular AC's when they stop working.. does the compressor kick on?

Valves are known to stick on the compressor. Did mine in.
