I had to have some one else lift them out of the boxes and install them( hoping that because the shipping people brought them to the door and left them NOT right side up that that won t make the cooling unit stip working) otherwise they have been doing a real good job cooling our front room, where is where the sun sets so its the hottest room except the garage family room, same side of the house. The second one i got for the kitchen window because the door to the garage room is straight accross from that window and the room is 15 to 20 degrees cooler now. Thank you.
