Could you please post your a/c pressures after the fix. It seems to me the high side is low for your ambient temp but your not low on charge. It seems to me one of the most important things a mechanic can do is look at data from good running systems so you can identify bad systems/ A/C electrical transmission whatever.
Make sure you blow out the outside of your condensor and radiator. It's amazing howmany cars I see with a/c problems and thats all that is wrong. I know that would give really high, high side pressures but it doesnt hurt.
