I did lots of research before I purchased this AC. My biggest concern was getting services in Canada in case anything happens. Today, I contacted them and they were friendly and fixed my problem right away. No fussing at all. The product itself, it is the best AC I have so far. I had couple of window AC as well as portable ones but this one really cools down the place. It's been little more than a year that I've been using this AC , so far very happy with product and customer service.
