Any good A/C books?

[sdguy55]

In the summertime we do a ton of A/C work. And i have gotten quite good at it and can figure out problems 99% of the time but would like to get a book and do a little reading up on it to try and be better. Any suggestions on a good book? I have looked up a couple and the haynes one has reviews that say it really only covers R-12 systems.

I can vouch for the one on the left.
Used that when I was a newbie. The tricks and advice still work

I've found the haynes book on mvac to be incredibly helpful.

I probably should have specified automotive A/C. I actually work on HD trucks only but i figure they will 'mostly' change over
