My air condition is not cooling good enough. It get down to 65 degrees and the compressor cuts off. Replaced the high side pressure switch and still didn't help. It cuts in at 90 lbs and cuts out at 50lbs on the low side pressure gauage. I change the expansion valve evacuated and recharged it back to 25oz. Still not cooling good. Does anyone have any idea's what I could do next. I think I have enough Freon in it but don't want to over charge it.

 

Welcome to HF. I MOVED your post as the New Member section is for introductory hellos.... not Tech Questions, just like it says stuck at the top.

 

Low side is to high. Check the high side too. If low on the high side, compressor failure.
