Yes, Vida can read the system gas pressure along with checks on other temperature sensors (cabin, evaporator etc.) and check correct damper motor operation so that air is being directed as it should.
You can also view the ac relay operation to see if it's coming on when expected.
I don't know the gas pressure off hand but you just double click on the value in Vida and it will explain what you're looking for.

A damp cabin filter or carpeting can also cause misting so check all windscreen drains to make sure water is being diverted and drained away as designed.
