Windmill Air 6000 BTU Window Air Conditioner Quiet and Smart App/Wi-Fi Remote Control

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.

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.

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.

While I fell for the sleek design, I have to say that it keeps me up all night due to the noise level. Sadly there is no low . Cools the room well enough.

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.

Some of the instructions were a bit confusing. When I went to use the QR code for a video explanation it was a dead link.

I purchased 3 of these units to cool my home. They arrived well packed, installation was a breeze, and they run quietly and efficiently to keep my home cool.The ability to operate them using the app is a big plus !

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.

Best company that really cares about their customers. They respond immediately when you email them. I had an issue with a new Windmill ac, and it was taken care of within 2 weeks. Thank you Windmill company how fast and professional you helped me. Best customers service ever,Lloyd Weatherford

Yes this air conditioner looks great and may run well for the first year but it has serious issues and the customer service from windmill is an absolute nightmare. My windmill air conditioner won't stop changing settings on its own. You set it to your temperature and it changes it to 60 degrees or 86 degrees. It beeps all the time, just changing settings erratically. Then the buttons stop working at all. Customer service has been unhelpful so far. Before you buy this unit please research it on reddit and learn about the isssues with settings changing themselves and temperature sensors reading completely inaccurately. Buy from a company that stands by its products and owns up to faulty products.

My new ac is beautiful and fits the room perfectly! Gentle cool is great!

It’s 3 feet from my bed and I don’t even know it’s on. Best purchase ever.

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!

Customer service is great and this is a very nice looking Ac unit. We’re happy with the purchase.

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.

I need to give it more time. It’s usually pretty quiet, but every once in awhile it literally shakes the entire wall and I can hear it on the floor below. As for cooling, maybe a B- at this point. It’s in a small room and can’t get it really cold. It doesn’t get a lot of use, so maybe I haven’t hit the learning curve.

Cools quickly, efficiently and quietly! Customer service very helpful, respectful and attentive.5 stars for sure!!

Thank you for your expert customer service!!5 stars!!

Head an issue with an AC unit that arguably wouldn’t be covered by warranty and the company went above and beyond to make it right. The customer service is amazing!
