No I don't think either of the lines in the front should be cold, since I believe they are going to and coming from the condensers. The only line that should be cold is the suction line coming from the air box. The other line may be cold going into the air box if the expansion valve is up stream of the box. I'm not sure where the expansion valve is located in this system. But if I had to guess it would be at the inlet of the evaporator coil. So the larger line leaving the air box should be cold.
