A/C has freon but not cooling on 1995 Cadillac DeVille

Checked with a mechanic that the A/C is normally freon charged. Changed also the drier/accumulator and the orifice tube but still the A/C doesn't cool as it should. The compressor I can hear it is doing it's cycles. The low side line is ice cold. The drier accumulator is warm-I'm not sure is way it should be. Inside car the blowing temperature in the recycling mode is around 70 F in a low city traffic and goes to around 63F on constant speed like on a highway( engine puts more power). I know a good A/C should give a temperature in 40 range. Please advice me Is that a bad/old compressor or there are still other options/problems to look around?

Thanks,
Bob
