Was talking to a fellow tech and he has seen some issues on a new Goodman HP.
He sat a goodman 5 ton single phase heat pump GSZ130601 unit only to have a stuck reversing valve. Or 4 way valve if you fancy!
Would not pump either direction.
Got a replacement condensor only to have it do the same thing.
They put a 3rd 14seer condensor in and all was fine.
Will we see widespread problems?
