The smaller line going to the expasion valve is the high pressure side and should be warm. The larger hose which leaves the evaporator and goes to the suction side of the compressor should be cool.


I have just the opposite of that. I don't know how that can be cuz the lines can only be installed one way and the compressor can only turn in one direction. Can you think of any condition that would have the "hot line" "cold line" thing backwards?
