What he said. This guy might be trying to take you for a ride (no pun intended). I don't know anything about A/C, but damn, $1200 for replacing that stuff?
Yeah, it is really annoying because I've been going to this shop for a few years now and they've always seemed pretty above board. This just seems way out of wack though.
Ok, here is how those parts could have failed. The hose, low or high side, could have a hole which would allow the refrigernat (R134a) to leak out. When R143a leaks out it carries oil with it causing a lack of lubicant for the compressor. Compressor contiunes to operate on a low charge unitl one of two things happens:
One, the refrigerant low pressure is below 20 psi, compressor won't engage.
Two, the compressor lock up due to internal failure.
If the compressor fails, it is standard practice to replace the drier, which filters the R134a.
To check to see if the compressor is locked up, grab the clutch, not pulley, and see if you can turn it by hand, with the engine off of course. If the compressor can't be turned it's damaged, if it does turn then maybe you only need to change the hose that could be leaking.
