Customers Say

AI-generated from the text of customer reviews

This modern window AC unit delivers a refreshing departure from bulky traditional models, featuring clean lines and a sleek profile that actually enhances room aesthetics. Its upward-angled airflow creates an even, whole-room cooling experience, while operating at whisper-quiet levels that won't disturb sleep or video calls. The smart features, including remote control via a mobile app and automated scheduling, offer convenient temperature management, though connectivity can occasionally be finicky. Installation is surprisingly straightforward, typically taking under 30 minutes with clear instructions, though you'll want a helping hand due to the unit's weight. While the ECO mode's temperature regulation isn't always consistent, the ability to track and optimize energy usage makes it appealing for environmentally conscious users.

Rated 5 out of 5 by from Amazing difference Upgrading from 5 year old ACs to the Windmil WhisperTech made a massive differnece in our home. We needed the silence for my partner's home office where he's on video calls all day and couldn't believe how well it worked. We ordered 2 more for other rooms. The change in volume is remarkable, the ability to control them from an app makes keeping the pets comfortable without breaking the bank much easier when we're out, and I LOVE that they dont blow directly forward, but up and around instead. So much easier to sleep without getting congested when an AC is not blowing toward your face. We did have a small issue with one of them, and they promptly replaced it when I sent a video of the issue. Love this product and company.

Rated 5 out of 5 by from Great customer service!!! This is a replacement model for a unit just barely out of warranty that, for some mysterious reason, started icing up. I contacted customer service who helped me troubleshoot it and it was deemed defective. They asked appropriate questions, like the size of the room, and then sent a new one. I can tell there have been some improvements, and it works great!

Rated 5 out of 5 by from Warranty I had a windmill ac for over a year and it was awesome. I bought one this summer and had issues with the wifi in the unit. After some back and forth Windmill sent us a replacement unit. It was nice to see them stand by their product. Highly recommend Windmill for performance and now customer service.

Rated 5 out of 5 by from Wow. I’m not sure what is better. The product or the company The customer service of this company is amazing. Sometimes. You take chances with smaller companies. And I’m so glad I took the chance with them. My room is ice cold and it’s amazingly quiet. I have the whispertech and it makes its promise. Any questions you have. They get back to you right away. Like. Right away. Maybe an hour response time. I love the product. I love the service. You will not regret your purchase. Thank you guys and gals at windmill. Keep it going

Rated 5 out of 5 by from Great product - great service I've been telling everyone how happy I am with my Windmill AC. It is such a thoughtfully-designed product: energy efficient, whisper-quiet operation, visually appealing. I also love the fact that the cold air blows up at a 45-degree angle and can't believe every air conditioner doesn't offer this feature. It was worth every penny. The company's customer service is also terrific.

Rated 5 out of 5 by from Terrific in every way! As luck would have it, I received a defective AC the first time around. Product support got on it right away, with numerous communications. Today I received a full replacement (actually upgraded from 8.000 to 10,000 BTU's). It works like a charm and cools things off incredibly fast and efficiently! This is our first AC (hard to believe, as we are in our 70's and somehow got by with fans). We are total converts! Anyway, our whole experience with Windmill and the staff has been perfect. Great product (and support). Thank you!Eric (Norman)

Rated 5 out of 5 by from Never disappoints! Just installed my 5th Windmill AC. The process is a snap and I love the wifi option too. When I experienced shipping damage from a 3rd party vendor, the customer service at Windmill was superb! A replacement AC was sent in a few days. Try Windmill and I promise you won't be disappointed!

Rated 5 out of 5 by from Windmill 10,000BTU I bought the Windmill 10,000BTU AC The unit is so quiet, that sometimes I forget that it is on. The room cools down quickly and desipte the price I would recommend it to anyone. It is at the top of the line.

Rated 5 out of 5 by from Super Quiet When I first turned it on, I wasn't even sure it was on! The compressor makes a tiny bit of noise when it first comes on for 4-5 seconds, and then after that I can barely hear it. It cools the room much more quickly than my old unit. After that, I can use the Eco mode to maintain the temperature. I was able to install the app with no issues.

Rated 5 out of 5 by from Customer service second to none We had originally ordered two Windmill 8,000 BTU units and one was great but the other rattled and was quite noisy. We were disappointed since one of the selling points of Windmill is that they are quieter than most. Customer service worked with us to trouble shoot but nothing helped. They then sent us a second unit in a very timely manner, and with no hassle. I would recommend this product and company to anyone without reservation!!

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 Excellent Service we have installed three windmill a/c units. they are easy to install, effective, and attractive. one of the windmills did not work properly. Windmill replaced it for a new one very quickly without making me return the old one which was nice (although it did cost me $10 to recycle at the town dump.) very pleased with windmill.

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 Windmill products and company response Overall, I have been very happy with Windmill products - very smart invention to include sleek design and the covering of the side fan panels - how smart!!! Unit looks cosmopolitan installed and not messy. Everything fits pretty snuggly for a good look in the home.Thank you!

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!
Date published: 2025-07-15
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.

Do you install?

Asked by: Susan
It’s a window ac so you need to place in the window. It’s a bit heavy so depending on your strength you may need help.

How do you change the filter?

Asked by: Mikie
You remove the front panel, which is magnetic. Then remove the filter screen and vacuum or lightly rinse/ wash with gentle soap. If washing, allow to dry before putting back in and running. Cannot recommend this air conditioner more! So easy to clean.

So I need a bracket outstanding de to hold this AC in window?

Asked by: Angela
In NYC, yes, it's the law.
Answered by: AGee
Date published: 2023-04-14

Does the unit ITSELF let any light in the room? I’m not talking about the brackets or the sides. I am asking if any part of the AC allows sun to creep through. 

Asked by: Jenny21
But beware - the vent is so close to the window, and shoots straight up. You will have to have flush mount shads if you want a dark room. The vent will blow behind any shade or blind that is more than an inch or two from the window.
