Split system Ac liquid line sweat in attic
Central Ac ,r22. Air handler in attic and condenser 20ft or so below on ground. No Ac issues. When Ac shuts off and then liquid line then gets cold when off so it sweats in hot attic and makes little water marks. I think this is because refregerant is equalizing after shut down. I guess? I have never seen this in 37 years of Ac servicing. Maybe it has been in places and I have not seen it. Thx
