The past times were at a shop, they evacuated the refrigerant, I swapped out High pressure switch, then they added it back in. They then tested for leaks and found none. It had held the same amount for the past 6 weeks, so that isn't the problem. Looks like it is going to the shop, I've had enough of it on my own. I'll post when I get it figured out.

Thanks guys

 

The pressures tell you more than just the level of refrigerant in the system, they are very diagnostically useful. But I understand, you have had as much as you can take trying to fix it yourself. Take it to a good shop that knows what they are doing and you should be fine.
