We bought this and installed it, but has given us grief Since then. We bought a different air conditioner for our son and like it so much more. His Is different air conditioner than the one we bought for ourselves. Ours changes the temperatures on you, or shuts down on you ( ours did this after ONE day of usage) saying the filter needed changed. We just remove the filter and put back in and it works for a few days or so and then the little red light is back on, or it changes the mode on you, but other than these problems it does cool the room down. Our son's is a different style of room conditioner and just keeps on running unless you manually turn it off. I think these problems almost outweigh a cooler room
