It has been a little over 6 months of having this AC and it has given me major problems. The AC stopped working in the middle of the night and refused to start again. I had to call the service men and they fixed the AC. The next night the AC started spitting out hot air even though it said it was on 18 degrees. I had to call the customer service again. It worked the next night. It is now the sixth night and once again it is throwing hot air. The service men came again and promised it was fixed for good. After a week the AC gives hot air again. Totally waste of money.
