looks like the prices are pretty decent actually, I would have charged more.
I would NOT have installed 134 in that car though. the engine temps are high, do they drop if you shut off the a/c?
as long as the temps do not EXCEED the 212 mark much you are OK. (that 3/4 mark is 212F not 190...)
I'm worried that the evaporator is packed. no way 24 oz or even 32oz (depending on weather or not, he used 2 lbs or 2 cans of "freon"
is correct. the bill also doesn't state how much or what type of oil was used...
compressorworks is a great brand compressor. I'd have a 4th bolt installed in the lower bolt hole through the compressor to keep it from rupturing.
