While I like the looks of the air conditioner, it is only slightly quieter than the one it replaced. It also short cycles constantly. The compressor will run for 1-2 minutes and then shut off for a few min and then do it again. It doesn't seem like there is a real issue, just the way it works. It doesn't seem to keep the room as cool as my previous air conditioner, which was much cheaper and lower capacity. I do like the fact that it blows the air up instead of straight forward.
