A/C repair questions

[jsbihn]

Hey all,
Well it turns out that my repair person last year screwed me when he "fixed" my a/c. Knowing it had a leak in it he basically said "here take your truck back". Of course, I was a little upset with him since 1) it wasnt right, 2) he worked on all the cars for the Corvette club, 3) he charged me at least 150-200 more then what he said it would cost and 3) he made me pay him up front. But I figured he had to be a good guy..... yeah well

Anyways, so I am back to my A/C and it turns out the one he put in had a leak in it, so of course I am trying to get him to fix it. Good luck.
But thats ok, I will make sure that others know what he did

So I am in a dilemma. The A/C parts are warrantied by NAPA and I can just get them swapped. But of course I dont have the money for the labor, and I can work on a vehicle and wanted to know how hard the a/c compressor and such is to swap out.
Like I said I am able to work on vehicles, I havent built and engine or a tranny but I can pretty much do the rest.

Any help would be great
