Something wrong with it or do you just want to increase efficiency?

Are the cooling fins on the condenser clean and straight? If you have a lot of bent fins or debris buildup that could affect the performance. Also too much oil in the system will cause cooling issues with the A/C.

Do you use the fresh air or recirculate setting? On hot humid days you will notice a big difference in duct temp if you use the recirculate mode. Instead of pulling all of the hot humid air from outside it will be pulling cool dry air that is already inside the car.
