I have owned this unit for 1 1/2 years and noticed it started icing up a few months ago. Kept on de-icing it. I had to de iced it about 4 times in the last 6 months or so. I did it again this past weekend and I called Newair to see what I can do to stop this from happening. The rep said that it was a known compressor issue and that they would have to replace it. When he asked me the date of purchase his tone changed and said Sorry it is out of warranty. So you will have to buy a new one or have it fixed at my expense. You got to be kidding me, this is an expensive unit it should last more than 18months! Left a message for a supervisor to contact me and guess what? No return call. Buyer beware!
