Q: New A/C compressor, air not overly cool...Why? on 2000 Chrysler LHS

Just had a new A/C compressor added b/c old one was leaking as determined with a dye test. No other leaks detected. Now the a/c blows cool air, but not overly cool. (Is parked in garage.) Why would this happen? My concern is the a/c wont be able to keep up as the temperatures rise this summer. Mechanic states a/c cools to 60 degrees! Isn't it supposed to cool to around 40-50 degrees? He claims if it cools to 45 degrees evaporator will freeze. I know freezing happens at 32 this not true for the evaporator? i have spent so much and feel i am being taken.

sorry that was confusing...i have driven it...for at least 20 minutes on several occasions...i meant it came out of a parked garage and didnt need to cool down from sitting in the sun and therefore having a high temp inside. any ideas now? thanks!
Depends on ambient tempture as to how cold the duct temp. actually should be. If it is 90° outside, 60° duct temp. feels pretty good. However you are right, 40° to 50° (F) is perfect. Measured at the center vent with setting on max ac and blower on low. The temp. at the actual evap. coil, at times, can go as low as - 30° F!! Keep in mind that R-134A is not going to be as cold as the old R-12 because R-134A evaporates slower! The quicker any liquid evaporates, more heat is dissipated. Now with that rant over with, (sorry) if you can find out what the guage readins are, hi & lo @ what ambient tempture and post, we may be able to help more.
