I am very pleased with this air conditioner! I have a three level townhome with only one HVAC system, and in heat of the summer, I just can’t keep the bedroom cool enough. I am forced to keep the entire house much cooler to just  keep it comfortable upstairs. This cools down the room quickly, and its climate control has been spot on. It is not that quiet, but it isn’t that hard to get used to the white noise. (Compare it to the classic window units in hotel rooms.) My HOA also forbids window units, but because there is nothing sticking out of the window, I’m hoping to not get a “nasty-gram” from the association, as the window insert is barely visible from the street, and shouldn’t distress anyone concerned with the neighborhood standards. -)
