The Windmill is the best window AC unit I've ever had. It looks great, is easy to maintain, has a good mobile app to control it remotely(not required, but useful), is easy to maintain, relatively quiet, and my favorite feature is that it blows cold air up, not out, so placing it in a window near a chair, seat, bed, etc. is much more comfortable than traditional window units. If you need a window AC, I'm not sure there is a better one on the market!

I have purchased 2 windmill window a/c units and am extremely pleased with them. The app functionality makes the unit truly impressive and well rounded. Creating schedules makes operation a breeze and lets me run the unit efficiently. When they are running they are very quiet compared to a traditional window. Having the fan blow up into the room instead of straight out helps cool the room quicker as well. Love the product, highly recommend.

I live in 100 year old building with 4 exposures (n,s,e,w). We have to rely on AC units to keep our apt cool. We bought 3 units and it has seriously helped. The units are understated, not obnoxiously loud and best of all the app woes quite well to turn the units on before we get home. It's so easy to program them to turn on and off that it almost feels like central air because when we come home it's actually cool! I had an issue with one unit and the customer service was also great. Stand out product and buying experience.

Excellent product and outstanding customer service! The AC does a fantastic job keeping the room cool. What truly impressed me, though, was how responsive, and helpful the support team was after I contacted them about an issue I had. They were kind, attentive, professional, and truly committed to helping/making things right. It's refreshing to see a company that truly cares about its customers, and stands behind its products. I'm beyond satisfied, and would highly recommend them to anyone looking for a reliable AC, and outstanding support!

I've been using windmill ACs for several years now, and a major plus is that I can control the unit via the phone app even when I'm not home. Not only does it work well, the design of the AC looks beautiful in my apartment. I used the original model (6k BTU) for 3 years, but after moving last year I decided to get the new WhisperTech model (8k BTU) and am super impressed with how much quietier it is and how quickly it cools my home. The customer support has always been fantastic as well!

I love my Windmill!!! Easy to install, cools great, and the internet controls are very handy.My first Windmill had a problem in summer 2025, and the Windmill support team couldn't have done a better job. They walked me through troubleshooting, and when we couldn't resolve the problem with my existing AC, they shipped me a new one.Easy to recommend Windmill!

Our windmill AC was a life (and sanity) saver this summer! It kept our home cool and was remarkably quiet for a window ac. Also want to thank Mike and his team for their quick responses when there was an issue with the first unit we were sent. They made what would normally be a stressful process very easy. Very happy with this purchase!

We have had so much bad luck buying ac units in the past and despite storing them as directed in the winter, they always seemed to die on us. After hearing about Windmill and reading reviews we took a chance on this one, and it was worth every penny. It's by far the most efficient, most quiet, and aesthetically pleasing ac unit we've ever had. It kept our home cool and comfortable throughout the spring and summer. And it was so easy to install and use.

Looked into several different ACs for my apartment and Windmill was the cleanest looking and most convenient. The app is simple to use and I love being able to turn it on remotely. Be sure to purchase the correct AC BTU for your space though. I was concerned the temperature censor wasn't reading accurately. But that was my fault given I was trying to cool a large space with a low BTU. Windmill customer service was very helpful in trying to help me regardless.

The Windmill AC actually looks good in your space, it's easy to install, and the app control is genuinely convenient. I definitely found it useful to control from bed. Cooling-wise, it does a solid job for small to medium rooms and stays pretty quiet! I've experienced other window ACs and they were super loud in comparison. Overall, I am glad I went with this one for my small NYC apartment
