Having said that, this air conditioner works well for what I need. Almost too well. I actually have to shut the AC off sometimes because of how cold it gets. It's a solid product. I have no complaints with any noise it makes (virtually none), leakage, installation (it's intuitive, for the most part), or otherwise.

It is heavy, but considering the value it delivers, I don't mind. If this is being bought as a gift for a person who cannot lift heavy appliances, I would recommend having a person or two to help install the unit.
