And remember if there is good oil carry over well have nice cold oil happily chilling the pipe and side of compressor.

but when any comes accross this it is prudent to make sure this is the case by checking the SH.

Sweating on the suction I agree is seen/felt whilst a system is working but not freezing on a cellar cooling unit that is around 11degrees set point, on lower temp systems I have seen freezing on the suct but if working properly never to the comp valve or body.

Im only asking to make sure of what I've been taught so I don't pass duff info on.
