I have been offered an old air conditioning unit by a relative. The machine is a Sears window unit that is fifteen years old and has never been out of the box. Only the top of the box has been opened but nothing has been taken out. The box has been stored in one place with top up. Will this machine work properly if I try and use it. I don't know the model number. All I know if that it cost my relative about $500 fiftenn years ago. Any help would be appreciated.
Cheers . . . J
