The metal label on the side of the upper unit bears no information, so I'm somewhat guessing as to the exact unit. In the owner's packet, there is a RVP consumer registration card bearing the information I'm forced to work with. Does it really matter which manufacturer I use for a replacement? All the a/c units I've looked at online components seem all the same. The replacement model for my a/c unit is a unducted model until you buy the duct kit. Is this what you mean by 'ducted models, there is no such thing."? And, as to the compressor, does it fail all at once? Works one time but not the next? I've read where they fail slowly. Is that wrong? Doug, thanks again for your valuable input/help.
