The AC has all new parts. We changed the compressor to a new one from the agency (LG). It has no mechanical defects, no freon leaks, and it's ice cold. The reason for selling is that I moved to a new house and the electricity is on the landlord, so I wanted to get a bigger one and keep it running all day. I repeat: The AC has no defects and is a great deal for whoever wants it. It's better than buying from stores and finding defects later. Everything in it has been changed from the agency.
