This is a portable aircon with one of the largest BTU around. It's 14000BTU while others are usually about 9000BTU. Bought it for $1200 and only used rarely. Can cool my living room of a 5 room flat on a hot day. Good for those who cannot install air conditioner in the living room or don't want the hassle of installing it. Should work even better in the bedroom because of the smaller size. Asking only $600. SMS me at 9- 8-3-3-5-6-8- 3 if you are interested.
