While this AC unit purports itself to be quiet, it is not. I placed this AC unit in my living room and I cannot hear my TV with this on. It is not quiet at all. It does do the job in cooling the room down so I gave it a 3 based only on the noise level. I am going to order a different AC unit once I can really find something that is quiet. I had a friend over and we literally almost had to shout in order to hear each other
