I was disappointed when using as a heater because the temperature mode was unreliable sometimes it was so hot and then at other times in wouldn’t come on and it be cold in the room for some time. The AC would shutdown at night and the beeping sound saying it was full of water could be bothersome. I had to add a drain hose because the reservoir was small. I would have liked a better air flow. I would like something better to cool. My facebook is gina calloway.
