Bests & Worsts Reviews from Amazon

I purchased this via Indiegogo. It arrived in perfect condition, and very well-packaged. Installation was a bit tricky. The quick-installation guide wasn't very useful and skipped over some important points (such as pitching toward the outside for condensate drainage, and placing the support bracket inside window opening and not directly under the window in the track). The instructions in the main manual were much clearer, though some pictures seemed to be in the wrong order. My windows are older vinyl windows with vinyl siding outside, and I had no issues as far as the fit, and the manual seems to cover most issues I could imagine would come up, including storm windows and older wood windows. It seems like installation will be much easier in future seasons, but still a bit more complex than traditional window units. (to be fair, I've installed and removed my previous window units more times than I can count, so I'm far more familiar with that process.) I decided to buy this 10k BTU unit to address two problems with the 5k BTU AC it replaced: too small and too loud. Obviously any properly-sized unit would fix the first issue, but it's the sound that really impressed me with this unit. You can barely hear the compressor at all. I mean AT ALL. You can't even hear it kick on. It's about as loud as a modern refrigerator on low and most of the sound is from the fan, more like a mini-split than a window unit. I also noticed there's no surge when the compressor kicks on, so if you have older wiring and have issues with lights flickering or breakers tripping when the AC kicks on (but your wiring is otherwise safe, of course) this will mostly solve that. As far as efficiency, the unit's auto and eco modes seem to add a lot for efficiency that basic units don't have. On top of that, this is the single most efficient window AC on the market right now according to the energy star website (i checked) so you really can't go wrong here. The only complaint I have is that the closed-window design doesn't allow blinds to be closed all the way. If sunlight coming in on either side is an issue (in a bedroom especially) be prepared to find a solution for that. Overall, I'm very happy with this unit, and it really is an innovative new take on something that hasn't changed much over the years. If you're looking for most of the benefits of a mini-split unit in a window AC package, this is the air conditioner you want to buy.
