★★★★★ 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 It’s sleek, modern, and blends perfectly with my apartment decor—nothing like the bulky, outdated window units I’ve had before.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!

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.

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.

Happy with this!

I had to buy a new AC because of a major recall on the brand I had. I'm really liking this unit. I feel like it cools more completely with less effort, it's quieter than most units I've ever had, and it's much nicer looking which isn't important but nice to have. My only, only wish is that they sold a support bracket for it. Needed or not I always feel better with it and my last brand had one designed for it so I got spoiled. :)

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.

great customer service

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.

Replacement unit

I cannot thank the windmill team enough for their help with a service issue. Everyone was nice, responsive and knew the a/c system well. When we found we could not repair, customer service reached out and replaced our unit. AT. NO. COST! Virtually unheard of. We went with windmill originally because we wanted a smart a/c (controlled on smartphone and Alexa) and a unit that was quiet. We are staying because of the care we received when we needed help. We will not go anywhere else for our cooling needs. It is only 95 degrees today. 🥵 But later this week we can’t wait to see temperatures reach 105 and hotter. We will be watching it all from our frigid bedroom. Thank you Skye, Maggie and Mike!

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.

Pleasantly Surprised

After long hours and sleepless nights of doing research, we decided to try the windmill AC with whisper Tech. Suddenly, our sleepless nights ended! These things are so quiet when set on low cool you would think that you're listening to a gentle rain on your roof. We really appreciate the fact that this machine works exactly as described, so much so that we bought a second one for another room in our house! The app is user friendly and easy to navigate. Cleaning the filter is a breeze compared to other machines we've had in the past. One of the extremely pleasant surprises, was the customer service. Their first machine we bought came from an authorized third party. We can't be certain but we think the machine may have been mish-handled and shipping. However, the support team at Windmill stepped up to the challenge. We had a new machine working perfectly in no time at all! Don't let our review convince you. If you want the room to feel like central air conditioning from a window unit, this is the one to buy.Sincerely, Spencer

Great air conditioner

Really love the Windmill air conditioners. This is my third. Easy to install and very efficient. One complaint with this one....the two I bought last year came with a cover to cover it in the winter months. I don't know why but the one purchased this year did not come with that.
