Do NOT buy this AC. It is extremely loud and does not sufficiently cool a room. When it turns on, it sounds like a plane landing. Then every 15 minutes or so, turns itself off with a loud "clunk". When it's on, it blows cool air, but then it turns itself off and blows in outside air so the room gets hot and humid, then cold. It does this all night long. If you want to sleep, stay away from this.
