Customers Say

AI-generated from the text of customer reviews

This thoughtfully designed window AC unit transforms the typical eyesore into an attractive appliance that genuinely enhances modern living spaces. Its standout upward-flowing air distribution creates an even, comfortable environment without harsh cold spots or direct blasts. While the unit requires two people for installation due to its solid build, the well-organized kit and clear instructions make setup surprisingly manageable. Daily life with this AC is notably pleasant - the whisper-quiet operation feels more like gentle white noise, and the WiFi controls let you adjust settings from anywhere, though connectivity can occasionally hiccup. The efficient cooling performance, combined with energy-saving features and simple maintenance, makes it a practical choice for those seeking both comfort and convenience.

Rated 5 out of 5 by from Redefines what a window AC unit can be I HATE window unit ACs. Like, with a passion, hate them. They are always dirty, dusty, smelly, loud and fall into the necessary evil category. I did not want to take a chance on this Windmill unit, but I did, begrudgingly. Well, I have been so happy to be proven wrong: this Windmill AC is WAY better than any window AC I have ever seen... I have seen many! It’s great for my office and no one can even tell it’s on during calls (& I sit right next to it). So pleased!

Rated 5 out of 5 by from ★★★★★ Best Window AC on the Market! I couldn’t be happier with my Windmill AC unit. It’s sleek, modern, and blends perfectly with my apartment decor—nothing like the bulky, outdated window units I’ve had before. Installation was a breeze (took me less than 15 minutes), and it fits securely with no rattling or drafts.The cooling power is impressive—it chills the room quickly and evenly, and the fan is super quiet, even on higher settings. I love the app and smart features too; being able to control it remotely and set schedules has been a game-changer for comfort and energy savings.Windmill has clearly thought through every detail, from the cleanable air filters to how easy it is to get replacement parts. If you want an air conditioner that actually looks good and works flawlessly, this is the one. Highly recommend!

Rated 5 out of 5 by from LOVE IT! I absolutely love this window AC. I have 2 of the bigger ones in other rooms that I've had for years and was so excited to see this small one. It cools my daughter's room so efficiently. It's quiet and looks amazing. I cannot recommend it enough!

Rated 5 out of 5 by from Worth the investment! I’m new to NYC so the summers here are brutal! I was looking into AC units this summer and a AD for Windmill popped up! I was intrigued with the sleek design but mostly the QUIET feature. I live by the train so that in itself is already loud, I didn’t want my AC unit to add to the noise. All in all I can say that Windmill is VERY quiet even tho I love that it’s silent I came to find that the best feature is the WiFi/app connection. Now, when I’m 30 min away from home I can turn on my AC from the app on my phone and arrive to a cooled home!!! Game changer! Definitely worth the investment for my situation.

Rated 5 out of 5 by from Beautiful Design + Superb Engineering = Bliss Windmill 8k WhisperTech is super easy to set up thanks to a step-by-step detailed graphic instruction booklet. Extremely quiet delivering a minimum of white noise and uniquely jets the air upward into the room. Controls are intuitive. And it is beautiful to look at and effortlessly compliments the room. I highly recommend this unit.

Rated 5 out of 5 by from Changed my life Who knew an air conditioner would be a revelation? THIS ONE IS. Quiet, efficient and well-designed. Buying this is in the top ten best decisions of my life, up there with where I went to college (UWSP) and not marrying that guy.

Rated 5 out of 5 by from quiet and powerful I bought the 6,000 BTU to replace a unit from another brand that had leaked water all over the bedroom. i got Taskrabbit to install it, snd they did a great job, so far the unit is everything I could ask for, and it is very quiet too,

Rated 5 out of 5 by from amazing. i bought two 8,000 BTU units for my apt (which is about 650 square feet) and they work so well! i have one in the living room and one in my bedroom, and it is MORE than enough to the point that i only run one at a time. installation was so easy. highly recommended.

Rated 5 out of 5 by from Wonderful company with wonderful products We ordered our first windmill product about a month ago. Setup was really easy and the design of the AC unit is aesthetic. After a few weeks we had a issue with what we think is the compressor. We immediately reached out to the company and got a quick response. After troubleshooting a few things we realized that the unit had to be replaced. Customer service was top-notch and they really stood by their product. They shipped us a new unit and everything is working perfectly now. Would highly recommend to all.

Rated 5 out of 5 by from Fantastic air conditioner! I couldn't be more pleased with my new Windmill AC. It's very quiet, cools my home office (which is in direct sun most of the day) in record time, and was relatively easy to install. It's competitively priced and was promptly shipped directly to my home. I would readily buy it again and recommend it without hesitation.

Rated 5 out of 5 by from It looks cool and it does cool! My air conditioner gets more compliments than I do! It is the most aesthetically pleasing AC you’ll ever find. And, if you’re in it for more than just looks, the performance is excellent! Everything from how the AC is packaged (so thoughtfully) to the installation (so easy) to the functionality (so versatile with WiFi) is A-plus. Can’t recommend Windmill highly enough!

Rated 5 out of 5 by from Compact and sleek! I've owned a number of Windmill ACs over the years... love their brand, app experience, and ease of install, but had always been bummed they didn't make a much smaller size 5000 BTU unit for a small room in my house. Now they have... and I couldn't be happier! It's compact yet powerful, and cools that room perfectly. Connects to the same Windmill Air app too. Definitely recommend.

Rated 5 out of 5 by from Such a sleek AC Love the look of this and the installation was pretty easy! Having an app for your ac makes it feel so fancy but it’s also so nice to be able to set it to whatever temp you need before getting into the room. It’s a great machine and blows the air up so it’s not blowing directly on you but is cooling the whole room.

Rated 5 out of 5 by from Heatwave savior! I had an issue with my original purchase and one day the device stopped working on me. It just started blowing hot air during a heat wave. The product was only purchased less than a year and I was very disappointed. Out of all days, it stopped working during a heat wave. Nevertheless, as I reached out to windmill customer support they were able to expedite and resolve the issue immediately. Thank you for resolving my issue and saving me from this summer heat.

Rated 5 out of 5 by from Works well and pretty quiet The AC is smaller and neater than my previous one and somewhat quieter. It cools well, but I wonder what my electric bill will look like.

Rated 5 out of 5 by from Few weeks in with my first Windmill Upon opening the unit I enjoyed the little details. Magnetic filter cover. Surge protector in plug., no more piped circuit breakers. Temperature light that goes off. Side panes that fit tightly in window, unlike any of my past units.

Rated 5 out of 5 by from Small unit has been perfect for our NE Ohio home I bought one of the small units for a bedroom we use as a television and entertainment room. It cools the room perfectly and is quiet enough for us to enjoy television in the same room. So I purchased a second unit for our master bedroom to replace an older floor standing unit, and it has been a better solution for us in that room too. Great little AC, easy to install and easy to control from app on phone.

Rated 5 out of 5 by from Best AC I have ever owned Easy install, quiet operation, beautiful design. Lots of thoughtful touches like minimal light at night

Rated 5 out of 5 by from Windmill window air conditioner I've owned 4 Windmill window air conditioners for several years and highly recommend them. I'm a picky consumer and I do a lot of research and expect good quality and this is the only brand that I will buy. It's a family company that truly cares about their products and customer service. The units are very easy to install. The units disperse the cool air in a way that is much more effective than conventional units. The remote control and the app makes setting and making changes very easy. The app reminds you when to clean the filter and it's quick and simple. The overall design is attractive and it sits in your window looking pretty and doing its job while blending nicely into the background. If you have any questions or need any help their customer service is top-notch.

Rated 5 out of 5 by from Blown away! I ordered the 8k whisper tech and all I have to say is wow! We live in an old home that doesn’t have central air, we do have a mini split, but if the bedroom door is shut, it can reach up to 80° in there. Some years we install the old, loud AC unit in the window but I don’t like it because it’s so loud and I wake up at 2 AM freezing. The whisper tech wouldn’t even wake up a cranky newborn. It is so quiet. I was a bit nervous about opening up the pocketbook because of the cost but it was well worth the money! Thinking about another unit for the spare bedroom. What I love most about this unit is that it auto shuts off when it reaches a certain temperature and the quietness
