I can confirm the same regarding the vacuum test. My truck's system hadn't blown cold for a few years. One place said it would NOT take a charge back then, so the compressor must be at fault. I wasn't willing to spend the money then for what was essentially a work truck. Also, the compressor had never made a bad noise.
This year/last fall I needed it because of it's automatic transmission (broken clutch leg from the bike crash), so tried a different place with a money back guarantee. They put vacuum to the system and it held. They got it gassed up (with dye added) and it worked great ------------ for a week. I took it back and they found the dye tracks all over the back of the compressor. Yet, it held vacuum.
