I am looking into purchasing an AC unit for use either in-window or in room. On Overgrow I know a few guys were convinced that purchasing an industrial-quality unit for ~$2000 was the way to go. I have always used the relatively inexpensive homeowner units purchased from home depot or the like but I was wondering if anyone has any experience with the higher-quality units and what the advantages were. As I understand it, the commercial-quality units weren't even necessarily higher BTU's than the cheap ones but they just worked better. . . Anyways feedback would be helpful. Peace.
