I hope the new condenser coil fixes your issue. Sounds to me like they (the body shop) caused damage to the system (given your description) but that would be hard to prove. The guys that charged the system, they should have made sure there was no leak after they charged it and ran it for a few minutes doing that system check (with a UV lamp), any tech I know would have done that after charge BECAUSE the charge was missing in the first place.. I believe you mentioned they injected dye, it would have been prudent to check that before giving you back the car since the reason you brought it there was to confirm a leak (or not) and charge it up. If they require you to pay a second charging after this, I would change shops. You do know replacing the condenser is within your capability, then you'll have just the charge to deal with (if the diagnosis is correct). Your original description below, a successful vacuum check would not be the 100% done deal because (I have heard of) a compressor shaft seal leak that might not cause a vacuum loss but will allow a pressure loss (after it is run and then pressure tested). They also should have checked both Schrader valve stems for debris as a routine lookover (again, because of the original loss of Freon). So, good luck with round two on this A/C issue!
