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.

I love the super quiet AC unit. Perfect for my home office-quiet enough for me to hold Teams meetings. Had an issue with the original unit, but the customer support was amazing. Followed up quickly and after just a few questions and uploading a quick video, they replaced the original unit. So impressed with the support. And anyone that comes into my office space is amazed at how quiet the unit is. And I love how I can control everything from the app. I highly recommend the product and the company/support behind it.

This AC is sleek and effective. We have two of them and they cool the whole apartment. When one of them malfunctioned gathering ice inside, we reached out to customer service and they resolved the issue immediately by sending a replacement! The new one is working great!

The a/c unit was easy to install by a trusty friend. I waited to write this until we had hot weather. It works beautifully. I really like that it doesn’t blow cold air right at us, but angles up. We do also use a ceiling fan in that room, but could do without it and the unit would still keep us comfortable.

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.

I own 2 windmill air conditioners and they are great. The last one I purchased was having some vibration issues but customer service was amazing and corrected the problem right away. I would definitely recommend these air conditioners. They are very quiet and kept my apartment cool the last few days when we hit 102 degrees in Boston!

I had a 10,000 btu unit that developed a startling rattle due to the compressor being too close to something metal and all it took was a few simple emails w/ a video and photos attached and they handled it from there.The new unit itself is aesthetically pleasing and is quiet to say the least. If you're used to the hum of a standard window A/C, this thing will make you wonder if it's even on. I worked with Mike, Lisbeth and Francesca - all of them were very receptive to my situation and quick to reply with help. Thank you team for all you did in making this new customer very happy.

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!

By far one of the best AC units I’ve ever purchased. It’s truly remarkable how quiet it is. Also the support team they have is equally as amazing! I purchased 2 of the WhisperTech 8000 btu units from Costco, both arrived and one unit wasn’t functioning correctly. The support team was very friendly and helpful. With a couple emails they were able to replace my unit. I highley recommend this company and their products! I won’t be buying any other brand of AC units going forward. Absolutely amazing!

I bought the A/C based on the Wirecutter review. My unit had issues. I sent video to the most excellent Windmill Customer service. The response time was amazing and my new unit is ready to be installed! I’m very happy to deal with a company that is proud to back their products! Thanks to the windmill team!
