Many of us are having trouble with the air conditioners, the 2 nd floor bedroom is like a sauna. While they have"fixed" it, the problem must be with the Ac system itself. I have closed all the vents in the basement. Only some of the vents are open on the first floor. They also added freon. Still no cold air on the top floor. I am paying for a unit that has Ac, however if the entire 2 nd floor doesn't get cold, then it's a problem. I had to buy a portable Ac to put in my bedroom to keep it cold. It's going to cost a fortune. Update. I was told by management there is nothing they could do about the a/c so I could be released from my lease. This unit 8177, needs at least a bigger unit or to be fixed before anyone else moves in. It's listed already . So I'm taking advantage of this nd putting everything into storage and doing some international travel.
