Well, after a week or so of working on my 60 in my spare time, I took it in to get pressure tested and charged...............and it is NICE AND COLD. I am very happy with it. I replaced the compressor, dryer, O-rings, and belts. By the way, I am using Freeze 12 instead of R12, and so far it seem to keep up great with the Dallas heat. I know there have been a lot of questions on this stuff, so I will be the guinea pig.
