hello, if you have changed your condensor then you have for sure introduced air into the system as a result of the change over. I recommend you take it to an AC shop so they can check for leaks at the connection points where you installed a new condensor. Once they make sure there are no leaks then they need to draw a high quality vacuum, to remove any air or moisture in the system and only then add 30 ounces of R134a to the system, making sure no air is reintroduced. If you continue to add refrigerant to the system without evacuating it with a vacuum then it will never perform very well due to the presence of the air in the system. Good Luck! As a side note I just replaced a leaky condensor on my boxster along with the receiver dryer, evacuated the system and refilled with 30oz of refrigerant and now I can achieve 41-42 DegF air temp on the exit of the vent with the ambient at about 82 DegF. I think this is pretty good, the car is as cool as I need it to be and the system cycles on and off indicating it is not under a heavy load to achieve this performance.
