Our builder installed a Climatemaster split system. We have condensation dripping off the liquid lineset (smaller diameter refrigerant line) in the attic, making a good sized puddle in the drain pan and wetting the attic insulation. The builder says the condensation on the liquid line is normal but offered to wrap the lineset with some tape to help insulate it. Is this actually normal for a split geothermal system? If it's condensing in my attic I'm worried it could also be condensing in the wall all the way from the basement to the attic and growing mold.
