I did a lot of research before I purchased our pellet stove. One thing I do before I make any large purchase online is attempt to call the companies tech support to make sure they are available. I do not deal with companies that have no phone support available. I had no issue both calling or chatting with Comfortbilt tech support, before and after my purchase. The stove was easy to install and Comfortbilt has so many video tutorials you might not ever have a reason to go to tech support unless you have a major issue. So, I have had the stove installed for about two weeks and so far we love it!
