I absolutely love this AC.  My old one was larger (more btu's) so when I bought this smaller unit, I was a little leery.  I need it for my living room, kitchen and dining room- so a large area.  It far surpassed my expectations.  Not only is it very quiet but it cools down the whole area I need it to.  I bought it in the middle of summer and during a heat wave, so not many AC's were available but I am so glad I found this one and purchased it.
