Check your pressures again.Sounds like the system is low.
20 is too high. Should be about 7 bar without the engine running and about 12-14 bar with the a/c on.Sounds like the system may be overcharged.
Slipping a/c clutch will not cause high system pressures.I think there is a restriction in the system.
