We've purchased 4 Windmill ACs over the years, replacing the old ones our apartment had installed. We've tried several of the older and newer major brands and Windmill is easily the easily the best combination of quiet enough to sleep with, quickest to cool a room, convenient (controlling and programming from their easy to use app), and best looking inside and outside (not so important but a welcome tally). Additionally, their customer service and warranty/replacement policies are great. Windmill's ac's work really well consistently, but nothing is perfect—when one of our machines inexplicably stopped working they replaced it really quickly (within two days!) at no charge. It's always nice to be able to support a small business when you can and it's even nicer when their products a great and they back it up.Oh, and reply to the owner's, Mike's, emails, he'll respond and help out when needed!Very, very easy to recommend Windmill.

We purchased three Windmill AC units at the same time after unexpectedly needing to replace our previous brand, and we couldn't be happier. Affordability was important, but so was finding something that was both powerful and quiet—especially with Chicago summers that regularly hit well over 100°.We keep our window units installed year-round since radiator heat can be unpredictable, and even in the coldest months our home can feel uncomfortably warm. Because of that, we also wanted something that looked great and wasn't an eyesore. Windmill delivered on every front.I was initially drawn to the simple, clean design, but the performance has been just as impressive. We've used these units for three seasons now with zero complaints. Bonus points for the seamless Google Home integration—we love being able to adjust the temperature remotely and keep our dogs comfortable when we're away.

I love my two Windmill window units! They are streamlined and effective, providing cooling without noise and provide a very clean, minimal look in my rooms. I like how the air comes out the top, like an arc, so my daughter can still work at her art table and not be blasted with cold air. Love the app management, too.

We have used the Windmill AC for the past two summers to combat the northeastern heat and humidity. After a summer of successful use, our unit's compressor unexpectedly stopped working during the second summer. The Windmill AC team helped trouble shoot the issue and when it became apparent that the issue couldn't be solved, quickly sent out a replacement unit. They were absolutely wonderful to work with! We were able to engage with real people the entire time. They made the process a breeze- pun fully intended! ;-) Within a few days, we had a new unit in place to combat the summer heat! The unit keeps our place cool, is a quieter than any we have ever used (and we have used them all!), and isn't an eyesore! Wins all around!

I got the 6000 BTU version for a teenager's small bedroom. The unit was great. Very easy to install. Looks sleek. Having it available through the app is a nice bonus. Plan to replace older, less efficient units with other Windmill ACs this coming summer

Summers in Texas Hill Country can be brutal, especially in a windowed room with no central air. This gem has made my Sunroom a cool utopia for my pack of rescue dogs. Everything about the unit was a breeze (pun intended). The order arrived quickly. It unboxed easily, and setup was detailed step-by-step in the instructions. As a 64 y.o. woman, I was able to do the install all by myself. And with the app, I can control its functions from my phone. I am so impressed, I also bought a Windmill Air Purifier and Windmill Fan!

I have had my windmill AC for 3 years now. It's the best window unit I've ever used. It's pretty quiet & very easy to clean. I love that the air blows up at an angle so I can still have things in front of it, but also because I really hate when the air blows straight on me. That's probably my favorite thing.

I ordered the Windmill for our living room to replace an old, very loud window air conditioner. The Windmill attracted me because it was advertised as being very quiet. The advertisement wasn't wrong. It was such a hot summer that we ran the Windmill unit a lot, and it cooled the space well with little noise. I will be replacing the few other window units with more Windmills as needed.

I purchased two of these units last year, and I am so happy with them. I'm happy for 3 reasons. 1. They cool the room down very nicely. 2. They are quiet, very quiet. 3. They look nice in the window - sleek.I have two more rooms that use window AC's; however, the current ones still work, so I can't justify purchasing new ones. But when I do, I will head on over to the retailer that sells these amazing units. Very satisfied customer who will be returning for another purchase or two.

Living in Manhattan, we have always had in-window air-conditioning that has worked to varying degrees of success from other brands. Windmills AC unit worked as expected, and the integrated app was extremely useful and user-friendly. It wasn't hard to install by myself. We ended up getting a second for our spare room shortly after testing the first. Living through the extreme weather of New York didn't feel like a challenge at all. Highly recommend. Oh, also, their customer service is phenomenal in my experience. There was an issue with our second unit, but once I shared the video of the noise it was making, they rushed shipped a replacement. Tryuely felt like they cared about their brand.
