Great customer service
Bought a 10,000btu unit a couple years ago and it was everything as advertised and when it came time to replace one of my older (non-windmill) units, I wanted to get a second windmill. Bought in August, but after installing, the unit had loud background noise from the compressor. Got into the chat with customer service and they walked me thru several checks to see if we could remedy my problem. After exchanging several videos and not being successful in fixing the noise issue, they put thru an order to give me a replacement unit. Easy, straight forward, no hassles, just good service.

WOW!!!!
We formerly had a 10,000BTU window A/C unit that had to weigh close to 100lbs. The Windmill 6KBTU was half that weight, easy to install and the app is really cool to control it away from home. And best of all, it cools the living room twice as well as its predecessor.

Great product and fantastic service!
We have several Windmill units and they are not only attractive but quiet and efficient. Most importantly, customer service is second to none! When we had a problem with our most recent unit, we received a prompt response to our initial correspondence. That was followed by trouble shooting ideas, and when these did not work, a replacement unit was immediately shipped to us. We are definitely very happy with Windmill products and the company's service.

Amazing AC with outstanding customer service
We bought 2 ***** BTU ac units and they are a game changer compared to the regular window units we had before. Besides the obvious esthetic of them looking sleek and modern, its amazing how quiet they run. The built in smart feature is very convenient and the fact that the vent doesn't blow straight out is really awesome. We had an issue with one of the units and emailed the company. Customer service was quick and efficient and we got a replacement super fast and everything works as it should. Wouldn't buy any other window ac ever again! Highly recommend!

GREAT AC - GREAT CUSTOMER SERVICE
I had an issue with the plug not working on my Whisper Tech unit and not only was customer service very quick to respond but they were also very quick to resolve the issue with a new unit. I received the replacement fast and it's working great! Very quietly, too!

If Form Married Function and had a Child...
After being thoroughly satisfied with the style and function of our first 8K BTU unit, we just installed a new 8K unit in our second bedroom. These ACs are amazingly quiet, efficient and user-friendly. And I love the WiFi connectivity feature through the factory-supplied phone app.One caveat: I had some difficulty connecting both units to WiFi. I forgot how I fixed the issue first time around, so when I reached out to the company for assistance, one of the co-founders replied right away and reminded me that the unit will be looking to make a 2.4G connection. My Google Pro WiFi Hub puts out 2.4G, 5G and 6G signals, so I think it was making it harder for the unit to find the right slot. I did manage to connect (maybe placing my phone a couple inches from the unit during pairing mode helped?) and all is working seamlessly now. As the title of my review suggests, it's the perfect combination of looks and functionality.We purchased this last one at PC Richard for $379 - which is a reasonable price to pay for such a well-designed product.

Quiet, Clean, and Efficient
I got two Windmill AC window units with Whisper Tech. They have been amazing with cooling the entire apartment. I love how easy it is to change and automate the temperature and modes using the mobile app. The units are also quiet with only the occasional sound of turning on. I also got the filter, which has made the air quality noticeably cleaner. Overall, a wonderful purchase!

Ups delivery
Product is great. Up air direction causes overhead fan to rotate which is better for getting over nearby furniture. Very quiet. Easy to install.Ups refuses to read special instructions needed because of construction. Windmill stepped in participing in solving the problem.

Incredible support
My Windmill 12,000 BTU AC ran into some technical issues. When I got in touch with Van in customer support, I was hoping to get some assistance, but was very pleasantly surprised with the level of support I received. He resolved my issue immediately and genuinely jumped through hoops to make it happen. Very grateful.

A+ Customer Service
My recent experience with Windmill's Customer Support Team was top-notch in every respect, probably the best customer service experience I have ever had! Here are a few things I was particularly impressed with:~ The promptness with which Windmill's customer care team responds to concerns and questions...~ The relevance, thoroughness, and courtesy of their communications...~ The whole team's in-depth product knowledge and overall expertise...~ Their inclination and ability to go beyond the limits of "policy" and "beauracracy" in order to do what is right for the customer...~ The support, help, and care that characterized the Windmill team's dealings with me from start to finish... To Skye, Simon, Rachel, Lois, and the product experts who worked in the background on my concerns: Kudos and Appreciation to all of you. Overall, a very positive experience. It will be very easy, and my pleasure, to recommend Windmill Air to my friends and neighbors.Thanks!~Wayne

Our new AC
A few days ago we received our new air conditioner (the Whisper Tech 8000 BTUs), and we couldn't be happier! It's been a miserable, hot and humid summer for the most part, and our old AC kept freezing up and not working. Windmill customer service was extremely helpful in resolving that. The new AC only took minutes to install and was working perfectly by the time we cleaned up the box material. Now we can cook dinner again... yea!

Far surpassed expectations : )
I don’t usually spend time reviewing products but this one was definitely warranted. Purchased the 12,000 BTU with the hope that it would cool off (at least a little bit) 2 rear bedrooms that share a Jack and Jill bath room and it does! And it does it well with both bathroom doors open and the main hallway closed off...which far exceeded my expectations- the rooms are actually really cool. Packaging was A+ and the install painless. It requires no bracket and fits snuggly in the window. It’s been a few weeks now and couldn’t be happier.

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.

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!

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

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.
