Your engine temp looks perfect.
Why evacuate? Checking the high and low a/c pressures can tell you a lot about the condition of the compressor and the expansion valve.
They rent ac gauges for free at autozone
Second thing that I would do is probe the a/c compressor clutch and install a light on the dash when the clutch is activated so that you can check if maybe you have an electrical problem sometimes and that the climate system doesn't activate the clutch.
