I bought a portable air conditioner and used it for awhile and it seems to work fine then, but in after some time of I hooked it up and it was not cooling off my rooms which was the kitchen and living room.i called to customer care but they do not any response of my problme So brought back to Home Depot , before some time the warranty expired and they exchange it for another. I finished talking to a tech from LG because the 2nd one is doing the same as the first one did. They will not warranty the 2nd one. Only on the first which the warranty has expired. So I am stuck with a air conditioner that does not cool the rooms. I will never buy anything from LG. They do not work with you at all or stand by their products .
