I don't even like working on boat A/Cs but like I said, necessity is
sometimes the mother of motivation or something like that. If we had
been at home I probably would have called my local service guy. I
know how to do some of this stuff but don't really enjoy it. I've
got 4 zones of A/C however and 2 refrigeration systems that I
installed myself. I carry hoses, adapters, gauge sets, a vacuum
pump, leak detector, refrigerant, tools, etc. but it is strictly out
of necessity. The tools and supplies pay for themselves the first few
times you (successfully) use them.
