I'm pretty sure you're spot on. They didn't want to over engineer the product. It's much more profitable to sell replacement units.
I didn't know recharge fittings could be installed in these units. This is the first I hear of this. It makes sense though. Last September while RV'ing I noticed both AC units were not cooling as well as they had in the past, primarily the unit in the bedroom. The compressor would kick on periodically with the thermostat being set at the coldest setting.
I definitely want to try to find an AC outfit that is willing to install the fittings and charge the system to the proper level before I have to replace both units. A mobile repair guy quoted me 1K installed per unit. OUCH!
