    I bought this AC in early July. The AC is energy efficient, as it used most 9-10 kwh/day during the heatwave, and set at 70F. Another great feature is its low level of noise. It sounds more like a fan, rather than other AC brands. The design is pretty and its easy to install. The downside is a bit pricey but its worth the money. I'm very happy with purchase.

    Aesthetically pleasing, noise level is great, not too loud for a big unit, but it does not cool my entire living room, it only makes it fresh when outside temperature is in the 70 degrees. But so far in 80 and 90 degree days it has not been efficient. I am not sure if the AC unit is not performing well due to the AC sleeve not having a lot of ventilation, or what other reason could be. I would love to return it and get a bigger unit. Maybe a 14k BTU for my 300sq ft living room but I didn’t realize Best Buy only offers a 15 day return period. So overall I cannot say it’s a bad unit but it has not worked for my space

    This AC is super quiet on the low setting - so much so that you might even forget that it's on. Love that you can turn it on in advance with the app.

    Appears to have died on me with mere months of purchase and use. Not sure if there was a problem which also caused it to fail at its basic job of cooling roughly 650sq ft or less. Two stars because customer service with windmill has been responsive so far, but a failure should not have happened so soon, especially on the highest price model

    I installed this unit for my older neighbor who can't lift anything heavy. It's well built, and it comes with more permanent insulated foam finish panels, which looks 10 times better than the accordion sliders alone, and provides less loss of cold air in the summer, and heated air in the winter if you leave the unit installed. BEST PART FOR ME BEING THE NEIGHBOR WHOSE HOUSE IS 20 FT AWAY, IS THAT IT IS SOOOOO MUCH QUIETER THANK THE PREVIOUS UNIT SHE HAD!!! The old unit was so loud, i couldn't leave my windows open.

    Obsessed with this AC!!! My last window AC unit was bulky, ugly, extremely loud, and horrible to install/uninstall. This one is a game changer! I would definitely recommend.
