This thoughtfully designed window AC unit transforms the traditional cooling experience with its smart capabilities and refined aesthetics. The upward-facing vents create a gentle, central AC-like airflow that evenly cools rooms without uncomfortable cold spots. While its whisper-quiet operation lets you sleep peacefully or work undisturbed, the WiFi-enabled app adds remarkable convenience - from pre-cooling your space before arriving home to adjusting settings from bed. Installation takes about 30 minutes, and maintenance is straightforward thanks to magnetic filter covers. Though occasional connectivity issues or temperature reading variances may occur, the unit's powerful cooling performance, energy-efficient operation, and premium construction make it a standout choice for modern homes.

Rated 5 out of 5 by from Replacement is saving our hot summer I bought an AC last summer. It was working fine for the summer. It was getting hot in Spring 2025. I started up the unit and it was making weird sound and stopped working. The unit made noise, so I knew the compressor was working but no fan noise. I contacted Windmill customer service. They had me go through a few tests on the unit and they told me that the unit is defective. They shipped a replacement immediately and I received it within a week.That was June 2025. Now it is mid Aug, 2025 and it is going well. We had very hot July in Chicago area. I am happy with how Windmill CS helped me out.

Rated 5 out of 5 by from Fantastic AC unit The design is sleek and it’s much quieter than the previous unit we are replacing. The customer service really is outstanding. I had a question about the size I would need for our room. It was a Saturday so I really didn’t expect to hear back from someone but I did and it was within 45 minutes. I also had a small problem with the unit we received and it’s been handled with ease. I also love being able to use an app to control it. Everything was very easy and were very pleased with the cooling and efficiency.

Rated 5 out of 5 by from Excellent customer service Our AC unit was making a lot of noise. We were asked to answer questions and send a short video of the problem, which we did, and they immediately sent us a new AC unit for free. They even followed up when they didn’t hear back from us initially. Very impressed with this customer service. Hoping the new unit is quiet as advertised, and if it is, we will be loyal Windmill customers!

Rated 5 out of 5 by from Great customer service. I can’t say enough this company has great customer service. A/C stopped working I emailed them on a Saturday and Skye emailed me back within 20 minutes, we went through all the steps to find out what was wrong with the system. When they reviewed everything they found it was the unit that was not working they sent us a new unit awesome was not expecting that at all. Very thankful because the east coast was getting a heatwave.

Rated 5 out of 5 by from Exceptional product and exceptional service We ordered 2 10k btu quiet units for our home and received them quickly. Unfortunately one of the units did not work properly. An email sent to the support team was responded to in a few hours, troubleshooting services suggested, and when that did not resolve the problem a new unit was shipped out to us quickly. It’s always frustrating to get a product that’s not working properly, but a great company sets itself apart by making a resolution quick and painless. Very satisfied with our purchase and will add a few more units to our 1525sft home in the coming season. Compliments to the design team and the customer service team.

Rated 5 out of 5 by from Our new A/C is working GREAT! We ordered an A/C unit for a window in our apartment. It arrived as scheduled. It was easy to install and set up. We are enjoying the cool apartment since. We also found that one of our cats likes to sleep in front of it...

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!
