Original unit was functioning as "Fan" only. No change after troubleshooting. Windmill customer service was responsive and supportive. New replacement unit (no additional cost) now installed and fully operative. Something of a novelty in the year 2023 to have a company whose customer service is easy to access and who stands behind their product. Highly recommend.

Couldn’t believe it was on. The sound level is incredibly low and at its noisiest sounds like a light rain outside. I don’t have to use sound proof headphones to take phone calls anymore. It cools the room quickly, keeps it cool and is a complete life changer. So glad it’s now in my life!! Windmill rocks! Worth every penny.

The unit is very attractive, though mine arrived with a slight dent in the housing. Installation was fairly easy, though I had to adapt it a bit due to my storm windows. It cools very well, however it does rattle and buzz. I had to tape the filter to the unit to stop vibration noise. I am least satisfied with the way the unit and app communicate. I have deleted and reinstalled it, but the app always registers the room temp as 67 and watts used as 20. There is a long lag between turning the unit on in the app and it actually coming on. I had it set at 68 and when I woke up, the display on the unit read 59--a little too cold.

I'm pleased to have a working AC... Yesterday was the first day I turned it on. The several different sounds it makes are distracting. Will I get used to them? That's why a 3 star. I was expecting a 9x quieter AC as was advertised. The staff were / are so nice... I really hope these are only the break-in period sounds. Joan

My son helped me install my new Windmill AC yesterday in my tiny cabin in the mountains. The setup was so easy, and the AC started cooling right away. I love the remote control feature. The cover I ordered also arrived and it is well made and will definitely provide that added style and insulation this winter.

I chose the Windmill 12k BTU over a cheaper, different brand 12k because of the direction of the airflow, and it's awesome and so worth it. It cools the room effectively without it being a jetstream of cold air in one direction (my window is nearly behind my couch, so past ACs have directed the blast at the back of my head). The first unit arrived and had a strange rattle in it, but we installed it anyway. Within a day it froze over with an inch of ice all over the insides. Contacted customer service and they responded super fast-- walked us through a few questions and quickly determined it was likely a damaged unit. Warrantee claim initiated, and a new unit arrived within a week. Honestly I couldn't believe how excellent the customer service was. If I need another unit for another room in my house, I'm going with Windmill because I know if any issues arise they will be taken care of promptly and efficiently. My only gripe is I wish there was a little more control within the app-- if set to "cool" the unit seems to keep cooling even as the room temp drops below the set value. It would be nice if it powered off and back on later, but maybe it switches to fan only and that's enough? It could be nice to link it with a different thermostat reading too, as it's interpretation of what temp the room is at seems a bit off when on eco or sitting idle. I imagine these things might get dialed in with some software updates. I'm also a big fan of actual buttons on the unit. If I can't find my phone I can still turn it on and choose settings and temps without any difficulty. All in all, love you guys. Great product, great company. Keep it up!

I’m extremely happy I bought this AC for my living room. I love that the air blows up because the only window I can install the AC is next to the couch. It makes it so much more comfortable. I’m amazed at how it can cool off 2 rooms with the setting on low. The true test was two 90 degree days and it held up! Only downside is I couldn’t cut the plastic panels easily with the scissors they provided but even without them the ac is still very pretty. Installation was extremely easy. I still can’t get the WiFi working though but not something I need.

Installation was simple and the unit is attractive, although maybe a little bigger than I anticipated. I also expected it to be much quieter, which was maybe wishful thinking but it sounds like any other AC to me, not necessarily quieter or smoother like it was advertised.

I absolutely LOVE this product and would highly recommend.This AC window unit is sleek and modern looking but still gives off enough air to cool down the living room. I’m thinking about purchasing another for the bedroom. I hired a task rabbit to install, although it looked easy enough to install myself, in which the Windmill AC website had a direct link to book and had directions listed in the task description already for you. It was super simple and took the tasker 15 mins to install. He was also already familiar with the installation which made me feel comfortable. Overall, from purchasing, delivery, and installation I was super impressed with the entire process! 100% worth the investment!

I love this air conditioner mainly because it tells you when the filters need to be changed and it's simple easy. The front cover is magnetic clean them, put them back on there chain. Let it know that you changed it and it's good. Also it blows air up and so it kind of blows up air up and out and I like it freezing. So all my friends have always complained about the air conditioner in my bedroom when they come in there but not with the windmill because it blows up and out and everybody's fine.
