This air conditioner worked well the first couple of days we had it, but one day all of a sudden it started beeping and the temperature changed itself to 86 and will not let you turn it back down. We had to wait an hour and a half to be able to turn the temperature back down. It doesn’t do it everyday, about 2-3 times a week it happens. When acting crazy, the remote won’t let you do anything nor will the buttons on the ac itself.
