The whole package

Let’s face it, air conditioner’s are an eye sore. However, Windmill maybe the best looking of them all - it blends in quite well as you can see in the photo. They provide these adjustable side patches which block out air, and also serve to hide the ghastly side panels. Setup was straightforward, did it in 15min. Unit works well, quiet and cools my living room quickly.

Money well invested!

I purchased 2 units. I have a 2 story home. I live in the Pacific Northwest so summers can get toasty and if you have never been up this way... 85% of the homes DO NOT have central ACI did some research and when I saw Windmill's product I was on board from the the get go. From the sleek design and size and the options to customize the looks.To my surprise the units come with their installation kit and just like the box says... installation was a Breeze! So if you are on the fence on getting a window unit... I highly suggest this product. Support small business!

Best air conditioner

I’m a voice over artist and work in a hot booth in the summer and being able to have this running outside my booth while recording is amazing. It’s that quiet! I’ve never had an air conditioner this quiet before. Makes living in NYC in the summer so much more comfortable. It also saved us money on our electric bill

I just have a question I really didn't want to write it so I couldn't rate it. would this be able to be put on a boat. I understand you think this is probably weird but they do sell air conditioners for boats or I have read some articles that people have used a window air conditioner.

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!

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. :)

Love these units!

These units treated us very well this past summer! We loved our first one so much, we got another. We'd love to eventually have central air in our row home, but in the meantime, having reliable units that are aesthetically-pleasing is a plus. And being able to monitor and control them from our phones is SO helpful, especially when our dogs are home alone.

Great and stylish little A/C

Needs to replace the window A/C in a small bedroom and I chose Windmill for the easy installation. Happy I did. We have an old house and sometimes it tricky to fit window units so I liked the thought that this one was all one piece. No accordeon sides to lose or break since they are permanently attached. The app to manage the A/C (and fan) from away was simple and effective. I will probably add another unit for a larger room at the beginning of the next summer

Works great, keeps me cool, and love the app

This window unit has been a lifesaver in an old house without AC. I love the automatic settings on the app so that I can turn it off or on remotely and save on energy costs when I’m not there. I like using the fan setting at times overnight for some white noise as well. It was easy to install by myself as well

Bought Two Units--Love Them Both

I bought the original 6BTU unit for my bedroom and the super quiet 10BTU unit for the living room. Love the remote option. It's great that you can turn them on before you get home. They are quiet and efficient! I highly recommend them. Oh, and customer service is great.
