Used Day & Night 4-ton outdoor air conditioner condensing unit (Model N5A4S48AKANA). Manufactured in May 2025 and utilizes R-454B refrigerant. Shows light exterior wear from normal outdoor placement. We had this installed in the spring. It turns out it is too big for our home so we had to downsize for efficiency. There is nothing wrong with it. It was removed by professionals. You will have to pick it up and haul it.
