The purchase turned into a total fiasco!  Delivered  by a total incompetent driver who crushed it rolling it end over end up a steep driveway. When asked why he didn't use the dolly in his truck he said it was too hard to get to. Was told to plug in the unit and see if it worked.......it exploded freon within 15 min.  You said tou were sending a better one but that one was sold out so you sent the original model which arrived upside down by the garage door and not the front door. I would never purchase from you again.  No one needs this kind of stress.
