Just a bit nervous about what I might have to pay a classic car shop to diagnose and repair my AC. It was converted to 134 in 2013 and ran cold for 3 months. I recharged it myself in 2014 and it ran cold for 2 months. The shop I'm considering, Automotive International in Charlotte, NC (labor rate $9 cannot provide an estimate or even a guesstimate, which I certainly understand. My concern is that they'll probably have to spend many hours trying to figure it out and have it just about fixed before being able to tell me the cost, which may end up being more that I can spend. I would LOVE to send my car to DMC or DPI but I just can't afford the shipping AND don't want to be without my car for an extended period of time. With all that said, I guess I'm just asking for folks to share their stories of having their AC fixed (find the leak and repair it) by a classic car shop and how much it cost them.
