Well, I'm at a crossroads with my Marine Air spilt system (Heat and cool). I have the 3 knob manual controls (2) and two air handlers. One air handler in the forward V birth area and another in the salon. Had the system recharged with R22 and ran it for 24 hrs. Clean both coils but only keeps the boat at around 78 degrees at night. Air coming out of salon duct measures 68 degrees (with a lazer gun) and 72 degrees in birth area. Temp of air going into the evaporators is 78 degrees. Compressor never shuts down. AC tech says the pressure was a little high when he was charging the system. Thought it might be dirt in the system blocking freon exchange.??? Don't know how old the system is. Anyway, how do I identify the BTU rating on the condenser. Label gone or painted over. Thinking I would change out the condensing unit first before tackling the evaporators. Or should I just scrap the whole thing and replace everything. Kind of at a quandary right now. I'm going down to the boat this weekend and run some cleaner through the water cooling system. Maybe it is scaled up and not transferring heat the way it should. Sea water strainer is clean and I have a good stream of water exiting the boat. Maybe, I'm overlooking something. Any ideas?
