We bought four of these for our family a few months ago when moving into a new house. AC and fan mode worked wonderfully throughout the summer. Come fall and we switch to heat mode, we began to see some issues. The condensation tank needs to be emptied up to 3 times a day in our living room. Annoying to be watching a movie and have to randomly stop to empty tank multiple times. The ones we use in our bedrooms need to be emptied every morning (no idea when in the night they shut off) and don’t even really keep us warmed to the temperature we’ve set them for. Overall, good as an AC/fan, but heat mode could definitely use some work.
