Very loud. Can’t hear the TV over it. Rattles. It does cool pretty well. I have only had it a week. I’ve heard from other people. Theirs died in a month, I pray mine doesn’t die, our summers here are 110 degrees. Right now we are in a heat wave. Heat Wave Alert at 105 and it’s only June. I would recommend this a/c in an area where there is more traffic. Otherwise it’s a pretty good a/c.
