Bought for a three season room, (16x 12) which got so warm we couldn't use.  The new Frigidaire portable air conditioner works great.  Easy set up into the sliding windows in the room.  We turn it on about a half hour before we need to use, and it cools the room just fine.  Was a little noisy at full fan speed, but when we turn down a little, it's much better.  Would recommend this unit for a bedroom, or any other type room, where a window unit is not able to be used.
