what is Perfect heat?? is there??

How hot is hot? I use a temp probe in my air vent to see the temp. I had just replaced my blower, ccu, expansion valve, and dryer this summer, so I am pretty exciting about having moving air. However, my heat lacks. I get about 85F coming out of the vent. I have been driving down the road in the middle of the summer and my compressor trips, and it gets up to 120+F.

Do I have monovalve issues? Does the monovalve regulate cold and hot or just hot? I think I might have read a vacuum leak can cause a faulty CCU??
