Worth Every Penny
I love my Windmill AC. It was easy to install (though did take two people--its heavy) and continues to look gorgeous six months in. It has made my 100-year-old top-floor apartment livable in the summer, without sacrificing aesthetics. I love that I can turn it on from my phone when the heat picks up unexpectedly in the daytime, and know my cat won't be uncomfortable. I recommend one to everyone I know!

Quiet, Stylish, and Easy to Install
Bought my second Windmill AC this summer and am so happy with both! Love the easy functionality of the app, and I really appreciate how easy they are to store off-season.

Love this
Have bought 3 over 3 years to replace my old window ACs so that I have them throughout my entire house. All three work like brand new and are super cute.

Loving our Windmill ACs in our old home!
We have an old, New England Victorian home. We got quotes for installing a cooling system through the attic that would have cost upwards of $20K that we do not have! Windmill was the obvious next best solution and we are so happy with our ACs. They look pleasing to the eye and are not an eye sore, run great provided you follow the filter cleaning instructions regularly, and can even stay in place during the winter. We love that they are designed with winter in mind - we don’t have any room to store them so currently they are still in place which the company actually recommends and with their stylish, fitted Winter AC covers. Their customer service is top notch also! They are extremely communicative and are happy to help support you in any way - trouble shooting the wifi connection with their remote control app, AC damage along the way (get the shipping protection!), or returns and refunds. We love you Windmill! A great company for all your cooling needs. :)

Great Air Conditioner and Beautiful Too!
Love my Windmill Air CONDITIONERS! I purchased 2 two 8K BTU Whisper Tech ACs last year. They work terrific, look beautiful and can safely and efficiently stay installed over my cold New England winters. Great purchase!

Fantastic AC, fabulous customer service
I love my Windmill! When FedEx delivered my unit, they left it on its side in a damaged box, and the AC had a rattle that wouldn't go away. I was wary of Windmill's email-based customer service system, but Eddy got back to me immediately and emailed back and forth with me in real time until he'd determined that the unit had to be replaced. FedEx damaged the replacement unit too, and Eddy and Windmill arranged for yet another replacement. The third one was delivered safely and works perfectly, no rattle, just wonderful cool air to help stabilize environmental conditions in my book conservation studio. And I love that it blows the air up toward the ceiling instead of across my workbench. I am so grateful to the Windmill team for their help and for making such a fabulous product!

Hands down the best window unit we’ve ever owned!
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.

Love my windmill!
I live in an old 1950’s cape cod style home that doesn’t have great insulation and that has an upstairs that is almost always the temperature of outside. This summer our ac also broke. We used a windmill in our main living area and in our upstairs bedroom and they were an absolute game changer. I love that they’re sleek and quiet, they don’t take up much space but do an incredible job and keeping the space cool. The app has app been helpful in that I can check the room temp from home or away and can adjust the temperature or turn the unit on or off. I absolutely recommend checking out windmills window unit if you’re in need of an ac in your space!

Happy with my cool 😎 new Windmill air conditioners !
I bought two Windmill air conditioners in May. They installed easily with the excellent illustrated instructions, I was pleased with their performance all summer long. So pleased, in fact, I purchased another air conditioner for my Granddaughter! Since I live in PA and it’s December, the heat is on. Very pleased with my purchases. Thank you and Happy Christmas 🎄 PS: sorry, I don’t have any pictures.

Great AC for My Apartment
I bought the Windmill AC for my apartment in NYC, and it’s been perfect. It cools my space quickly, runs quietly, and looks sleek—way better than any other AC I’ve had. The app is easy to use, and installation was a breeze.Definitely recommend it if you need something reliable and stylish without the usual noise.

Efficient and sleek. Best of both worlds. Add Bluetooth controls to the mix and you’re in the future.

Excellent AC!
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!

Awesome Air Conditioner
We got this for our bedroom earlier this year because the one in our living room wasn't powerful enough to cool our room down the hall. This cooled our room so quickly, and it was much quieter than the one our apartment provided. I love that you can use the app to set it to turn on and off at specific times so we wouldn't need to worry about our cats being too warm during the day.

And a bag of chips
I now have three units covering two homes and they are everything I hoped they would be -- and more! Quiet, effective, and convenient (with device management through my iPhone), I have recommended these many times.

Best window unit
Saved us from the Oklahoma heat this year when our central air went out. We currently have two units at the house and it cools those room down really well. Super easy to install!

Great working and looking AC
From the installation to keeping my home cool, to removing it for the cold winter this is the best AC of all! I have had many ACs and this is best looking and efficient.
