If your mech suggested a higher pressure compressor, I'd find a new mech.
The first thing I'd check would be the condenser and radiator for partial
blockage. They have to be clean for the fan to pull enough air through them
to work efficiently when idling.
Also check the belt for glazing. It could be slipping.
Another possibility is a door not closing(or opening) all the way in your
heater.
A good A/C man could find your problem quickly if you're willing to spend a
few bucks.
