Peace, mercy, and blessings of God be upon you. Smart Samsung AC with Wi-Fi, excellent cooling, 21,500 BTU. I bought it a year and a half ago or less from Extra. The invoice is available and the warranty is valid. I used it little because I'm at work most of the time. The AC is very clean and almost new. The original price was over 3,300. I'm selling it for 2,000. Reason for selling: Final exit.
