Well, I hope this is my turn to add some value to this forum. I have certainly gained extensive knowledge and solutions to my issues from you all. THANKS!
I have a 79 58’ MY, galley up. It originally came with the “Goofy” modulated AC system for the 4 staterooms. The original owner changed that and installed individual ACs. It has six compressors in all.
About 3 years ago I had 3 of my 6 CruiseAir units not producing cool air. I had an A/C tech come out and proceed to charge me several hundred dollars to recharge 3 of the units with R22 freon. Several months later they were not cooling.
So I went to work. I did a lot of research and here is what I discovered. (Note, I have not shared this with the forum until I determined this was a sound dependable solution. I feel, given the time tested, it is.)
My search found a company called Enviro-Safe Refrigerants www.es-refrigerants.com and a new refrigerant R22a that replaces the R22 and is fully compatible with the R22. I won’t go into the dynamic of the R22 becoming impossible to find, expensive and requiring certification…you can read all this on their web site.
I proceeded to purchase the gauges/hose sets, the sealant, oil and the R22a refrigerant in a 30# tank. I have the installation and charging documents from Cruisair and in fact a “slide rule” styled scale that assists in setting the proper hi/low pressures based on the seawater and ambient temperatures. The results have been excellent. I have gone through multiple seasons with no issues. I am seeing a 17-22 degree differential between intake and delivery air at each unit. My large salon A/C actually “smoothed out” an operating noise level after servicing with the products. The ”leak stop” worked well on 2 units. I did have to top off the salon unit (it was cool, but not cold) with Freon last month, but that took 10 minutes and probably cost me all of $4 worth of R22a Freon. BTW, the culprit was a slow leak at the schraeder valve and cover. I highly recommend you take a look at this as an option for your A/C maintenance.
