lines sweating


The refridge lines are wrapped in 3/4" i.d. x 1/2" wall K flex. Outside they run inside a soffit. I checked in there and the lines are sweating, enough that the condensation is dripping onto the vinyl soffit and keeping the space wet. The run is approx 30' from where it exits the interior to termination at the outdoor unit. The K flex is slipped on and sealed at the butt joints. The sweating is along the entire run. The home is in coastal Georgia, a very humid environment. I would appreciate any ideas on a fix.

Thanks!

might need thicker insulation or the line is frosting back.

Is it cooling ok?

The system is working well, cool and dry in the house.

Maybe I should just get a large enough i.d. foam insulation to cover the existing insulation? Would it be OK to cover the entire set, including the un-insulated line?

I think so. It's been a hot humid one. AC working overtime would find the standard line insulation is not good enough.


Contact a supply house near you to find out the right thickness.

I'm a Northerner and even in this higher humidity my line insulation is good to go.
