I have 6 Sharp split air conditioners, their cooling is very good and they are very, very, very clean and have been used for a short time, and in some rooms their air conditioners have not been used at all. 3 are size 18 and 2 are size 12. Reason for selling: I am moving out of the region and have a furnished apartment, so I don't need the air conditioners. Whoever is serious about buying, please contact me.
