I'm in the middle of a second floor addition and want to run a line-set for future air conditioning. I'm going to run the line-set within the walls from the attic to the first floor. My question is when the system is installed if the future will the liquid line cause condensation within the wall since it is not insulated? When I purchased the line-set I was told not to insulate the liquid line because it will affect performance on a typical split system.
Please advise so I can run the line set and close up my walls.
