I've read the whole thread and although Larry Bible and I bump heads occasionally, I think he is giving you sound advice. I can only add a couple of things. I think you should find a shop that really understands A/C and you should turn it over to the shop and stay out of it or just do it yourself. When I had a full blown Indie, My rule was you work on it or we work on it, but we don't both work on it. I'm suspecting that your shop is not well read and up to speed on A/C. Just my opinion.
