I have systems where the compressor is a block of ice and they run great. As long as you maintain evap. SH 4-6* low temp 6-10 med. temp 10-12 high temp (everyone has a diff opinion on these) know that you compressor is safe from flooding unless like said before you have a long a$$ lineset that isn't insulated causing high discharge temps due to lack of compressor cooling.
To do a proper service always check the Stinky5
3-T.D across coil
5-Pipe temps(all 3)suction, discharge, liquid
I dont mind seeing ice all the way to the compressor but it shouldnt be encapsulated in it.
