Just a regular AC. I cried twice trying to get this thing in the window. It works nicely, not too loud and definitely powerful. The decorative panels look cheap and don’t sit flush to the window. I wanted to return it but that would have been too much of a hassle, and really I was just mad at how difficult the install was for me. I live in a brownstone with normal windows.

I was excited to receive my whisper quiet medium sized unit but there were some hiccups. The customer support team helped me deal with some shipping issues and after much communication, I now have my unit installed and it's great! really quiet. more quiet than the mini unit we installed last summer.

We absolutely love this AC. We got the 10k unit and find it cools sufficiently better than our previous 10k unit. It's also so much quieter, to the point that we don't even know it's on. It fit perfectly in our window, and we had no problem with the installation. Our only complaint, if it could even be called that, is that there isn't a Celsius setting for those of us who didn't grow up in the States.

Got a unit that was noisier than advertised, likely a shaky compressor. Messaged Windmill customer service. It was the greatest customer service experience I have ever had! Every response was within minutes. Within a day they had shipped me new unit. It works great, quite quiet. A+

I recently moved into a century home in New York, and as such, I don't have central air. Rather than spend the several thousand putting in a central unit, the simplest solution was an ugly, loud window unit. These are not that. They're surprisingly quiet. Especially compared to the portable unit I was using. Like, barely notice it's on quiet. And unlike my portable unit, this keeps my living room cold. Even this past week when temps were bordering 90ºf. Granted, I should have gone with the 10k unit, not the 8k, but it's working. So well that I ordered another for upstairs. And while not the most important aspect to some, the fact it's aesthetically pleasing is a major plus. It's 90% the reason I chose it. It keeping the house cool is of course important, but any window unit can do that. Also, the wifi features are nice. Sadly not HomeKit capable yet, though hopefully that will come soon with Matter. These are the only devices in the house that I need a separate app for. Not a dealbreaker, but will probably get annoying after a while. (Special shout out to the customer service. I had an issue with my first unit and they took care of it. My unit is once again working as it should.)

The unit arrived quickly It is simply excellent. It cools the room very well. It’s quiet. The design is really special in that it looks and feels modern and clean, both from inside and outside. The instruction manual is really easy to follow. After carefully considering many competing manufacturers’ products, I believe that I made a good decision in purchasing this Windmill AC. The only reason that I didn’t give it 5 stars, is that I have triple track storm and screen windows and installation was difficult. At first I tried mounting it flush with the storm window on a north facing window. I then realized that, when it rains hard, the rain will penetrate the accordion style side curtains and flood my window sills. So I moved it flush with the interior double hung window. When I lower my outer-most storm window, it hits the top of the AC and leaves 8” wide openings on both sides. I cut plexiglass to fill these gaps, but, because the unit is rounded, the fit is not perfect. It remains to be seen how much rain will infiltrate my window sill.

The Windmill was very easy to install by myself(took less that a 1/2 hour). The design is nice and clean and it quickly cools my bedroom. The controller is simple to use and easily understandable. The unit is a tad bit noisier than I would have liked. But, overall, it is a keeper and I am pleased with it.

It cools my office very well. It was heavier than I thought it would be but I still managed to install it myself. It looks nice and sleek. I will say the instructions ask you to screw it into the window but that doesn’t work with vinyl windows the plate to secure the window to not open farther also wouldn’t work with my windows. That said it seems very secure with the window down.

I order two different AC which One was yours and Midea AC. The Midea was not for our window and to complicated to put it together .The air condition windmill is easy to put in easy to use but in case of things that happened to me with an E3 that show on the screen didn’t know what it was. it would be good to put some instructions in the box on what to do instead of emailing people in the middle of the night to find out how to fix the problem unfortunately they didn’t know and they replace mine with a new windmill air condition with the amount of BTU my room is only 10 x 12 and it should be really really cold but it’s not, So I just have to deal with it . Need to improve the coldest on the AC. If you do that you will have a great product. If you improve it.

We love our Windmill A/Cs! They are so quiet and efficient, and more attractive than any other window unit I’ve ever seen. We had 2 units for over a year— and one stopped working. Windmills customer service was excellent! They quickly shipped us a new unit free of charge, even after our warranty was expired!
