Best A/C Unit Ever Made
We sent back a cheaper China-made model to a box store that sold it. It simply didn't work and seemed quite flimsy. We read about Windmill being stationed in the Big Apple, was impressed by what we read, paid more, and are so thoroughly satisfied, we would recommend this unit to everyone!

Excellent Window AC Unit
I own two Windmill AC units and love them both! They were easy to install which is important to me. They are easy to operate and they are surprisingly quiet! Additionally, I needed to contact support for an issue and they resolved it quickly and to my satisfaction. I very much recommend their products. - JT

Looks Great + Thoughtful Features
Just installed my unit in my home office and it’s an immediate upgrade on my old, basic unit. Looks great, has plenty of insulation, easy setup and control, and quickly cooled down my space and held it as a consistent temp.

Great product and customer service!
The product works great! I ordered the extendable side panels because our windows are 38 inches, but I didn’t need them. The original panels cover the distance just fine. Their customer service was amazing!!

A+ Service and Integrity
Windmill was the third brand of window AC units we purchased in 18 months (portable, u-shaped), and the only one who stood by their product. Customer service was knowledgeable and diligent, and shipping quick and on-time. The window unit is sleek, installation as easy as it can get, the app easy is to use, and it cools a room within minutes. Deciding on indoor, u-shape or traditional units? Go with Windmill - their design is thoughtful, the unit efficient, and service is top-notch.

The future of window a/c’s
These Windmill air conditioners set a new standard for the window a/c market. From the non invasive, sleek design and quiet efficient operation, to the second to none customer service and care, they are what all window air conditioners should be from here on out. They don’t cost much more than the old noisy, uneven air, obnoxious ones do either, and with their deals and discounts they are pretty much the same, but you get a much better quality unit, that truly looks good hanging out of your window. To anyone who is in the market for a new window a/c, I would highly recommend the Windmill. We now have 2 and I will not buy anything else.

Excellent product
I am very happy with my new unit. I purchased it mostly because I was impressed with the design, and i wasn't wrong. This is how ac units should be made.

Love!
Vaulted ceilings and I was skeptical...but it kept my house an amazing 69° during the last heatwave. 12k BTU version. Simple to install. It's pretty quiet, too, which is great for being on work video calls. Love it.

Good customer service
Easy to install, very user friendly. Easy to set up app. Unfortunately my unit was one that started making a loud motor noise, which you might see in some other reviews. However they have really good customer service. After sending a few videos they sent me a replacement! Francesca and Rachel and others were very responsive and nice. The new unit is nice and quiet. Make sure you register your unit!

Quiet gem
As promised, easy to install and quiet. However, the 8,000 BTU Whisper Tech model is large and heavier than I expected.

5 stars
I am so happy with this tiny sleek mighty window unit. After a day of running it felt like I had central air. It’s fabulous. Keeps the whole apartment/ room cool and the air rises so it really feels like central air. It’s sleek and really attractive and very minimalist. I replaced my old ac unit and it is quite the upgrade. Love all the panels too makes it sealed and attractive. Very pleasing to the eye. Keeps you cool. Love being able to control it with my phone. So awesome. Thank you. Truly life changing design for a New Yorker.

Stood by your product!
I purchased a Windmill AC in June of 2025. I used it during the summer of 2025 and put it away in the fall. When I pulled the unit out for this summer I noticed that not long after installing it the unit was not blowing cold air. I contacted Windmill and was worried that since it had been slightly over a year since I had purchased it (like many companies) I would hear that my year warranty had expired and there was nothing they could do. To the credit of Windmill, they stood by their product and replaced my unit with a new unit at no cost to me. Special thanks to Van who helped me with troubleshooting and the case review process on their end. Nice to know there are companies willing to stand by their product.

Outstanding Customer Service
I am very pleased with this window AC unit. It is very quiet and looks great. The magnetic cover on the front is a great design making it so easy to takeoff and clean the air filter. The windmill app is simple and straightforward, making it easy to use as well. The only problem I had was with the included remote control not working. I contacted customer service and had a reply from Rachel within 10 minutes! She suggested a simple fix, which did not work and so she had a new remote sent out to me which I received within three days. The new remote is working great. Thanks!

Great Customer Service
We had an issue with a new unit and got a replacement within a week of initiating contact - new unit was delivered in time for a big heat wave where we live in Southwest Colorado. We had an easy time setting up the unit and love the Wi-Fi interface. I highly recommend Windmill!

Great AC, Even Better Customer Support
We've been using the Windmill AC in our kids' room and overall really like the design and quiet operation. After about a year of use, our unit started glitching and beeping intermittently. I reached out to Windmill's support team, and even though we were technically just past the standard warranty window, they went above and beyond to make it right and approved a replacement unit for us. The process was smooth, communication was clear, and the team was genuinely helpful and responsive every step of the way — especially given we were dealing with this during a heat wave with young kids at home. It's rare to see a company stand behind their product like this. Highly recommend Windmill both for the product itself and for how they treat their customers when something goes wrong.

Great air conditioner and top tier customer service!
I have 3 of these air conditioners and love them! They are quiet and wonderfully effective. During the recent heat wave, we used them nonstop. This is definitely a great family run business that deserves your attention!

A great new A/C unit
This is our second Windmill unit that we own. The first one we got about 5 years ago and has been great in our bedroom. This summer our old wall unit died and I thought I would try Windmill again, only this time I was going to get the largest unit the have. This unit is 120 volt A/C which is nice since our old unit was 240 volt A/C. Now we can put the new unit in our living room window instead of the wall that exhausted into our garage which left the garage like a sauna. This new A/C unit is so quiet that at first after installing it I honestly thought it was broken and not working lol. An extra awesome benefit of this new one too is the iphone app so I can turn it on an hour before we come home from work and have the room cold. These new units are amazing and I will most likey buy another one for our bedroom since it so quiet.

Loving it
Super sleek little machine, and love having a window unit that doesn’t need to have the ugly brackets on the outside. The eco mode has been game changing, as all our other ac units are either on or off all the time. This thing has me wanting to upgrade all our existing units!

I own three of these they are so good. I had a shipping issue with one and the team immediately got involved and resolved the issue in 24 hours. I can't say enough good things about these. Also, they are as good as they look.
