Powerful AC

Would Recommend

We absolutely love our Windmill AC. It's incredibly powerful and cools our apartment quickly, even during the hottest summer days. The sleek design is a huge upgrade from traditional window units, and it's so much quieter than we expected. Perfect for small NYC spaces where every detail matters. Highly recommend!

Don't hesitate, they're great!

Would Recommend

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...

Very quiet

Would Recommend

We needed a better AC to cool our first floor area and our old one was so loud and inefficient. I saw an ad for Windchill and figured we give it a try. Needless to say I want to purchase more to put in other areas of my house. Really glad I got one! Highly recommend.

Attic cool

Would Recommend

The windmill was great find and quiet option. I have 3 of them in my attic apartment and it really cools the entire apartment in the hot summer months. It also blends in with my aesthetic and not an eye soar.

Best Window AC Unit by FAR!

Would Recommend

Before purchasing the Windmill AC Unit, I tried a more established brand and ended up returning it within two weeks—it was loud, difficult to use, and barely made a difference in the room’s temperature. As soon as I installed the Windmill, the difference was immediate. The air felt fresher, the sound level is perfect (more like subtle white noise than an AC unit), and the sleek design fits seamlessly into my space.The app is also incredibly user-friendly, which makes controlling everything easy....

One of the Best Designs

Would Recommend

I haven't seen any AC's look this modern which is one of the main reasons why I got it. It's also quite compact for the BTU's it delivers. The app is a plus when I'm away from home or even when I am home and too lazy to get up. Would recommend.

Definitely worth it. good if you have sensory issues

Would Recommend

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.

Solid AC unit

Would Recommend

I live in 100 year old building with 4 exposures (n,s,e,w). We have to rely on AC units to keep our apt cool. We bought 3 units and it has seriously helped. The units are understated, not obnoxiously loud and best of all the app woes quite well to turn the units on before we get home. It’s so easy to program them to turn on and off that it almost feels like central air because when we come home it’s actually cool! I had an issue with one unit and the customer service was also great. Stand out pr...

Great AC, quiet and powerful

Would Recommend

This AC really does a great job of cooling off our large living room in the summer, and is very quiet as well. Highly recommended!

Great A/C

Would Recommend

I needed to replace a 15-year-old 5000 BTU A/C this summer since it wasn’t cooling as effectively (and my town offered a rebate for recycling inefficient appliances). I’d seen ads and reviews of the Windmill, so I convinced my wife to let me order it. The install was very easy. The most difficult part was taking out the old unit. Controlling the unit via the app is easy, and I like the energy use meter. We also go out of town once a year, so the ability to start it the day before we return is ve...

I love my Windmill Air conditioner

Would Recommend

I have a small house in upstate New York that is about 1000 ft.2 and my 10,000 BTU Windmill Air extremely quietly cools the whole house even in the hottest days of the summer. It’s attractive, easy to change filters on, and extremely quiet, which is what I really need since I sit very close to it in my living room. It is certainly the best air conditioner I’ve ever had and I have suggested it to many people. It is well worth the money spent. I have now gone through two summers with my Windmill A...

Best window AC ever!

Would Recommend

I've gone through many window AC units but Windmill is by far the best. The installation is seamless and easy since the unit itself is so sleekly designed, no rough or sharp edges that could scrape you. Having it be able to pair with a phone app makes its use that much simpler, it's really a breeze. And it's so much more quiet than any other brand I've used. You can finally hear the TV even when the unit is on full blast, which is something that we used to overcome by using close captioning beca...

Wonderful AC

Would Recommend

This AC is great! It is so quiet, perfect for my living room. I really appreciate being able to control the unit on the app on my phone so I can make adjustments for my dog or turn it back on before I get back from a trip so my apartment is cool by the time I get home. This along with my air purifier were well made purchases from Windmill.

Exactly what I was hoping for

Would Recommend

I purchased this window air conditioner because my husband and I like to keep our bedroom cold at night for sleeping but I didn't want to waste energy cooling down and heating up our whole house. This was the perfect solution – easy to install without any special equipment and way quieter than any other window air conditioner I've ever used. We went with one just a little more powerful than we needed for our space because we wanted the quieter motor and I'm happy with our choice. I also like tha...

Total Game Changer

Would Recommend

Windmill is the best AC I've ever owned! Incredibly easy to install, very efficient (which is a challenge with 100+ year old, single pane windows) and most importantly phenomenally quiet. I've had such a great experience with Windmill, this is the third unit I've purchased. One for my bedroom, one for my downstairs and one for my wife's office. The bluetooth controlling during the summer is a huge plus!

Pre-Civil War home in southwest Ohio

Would Recommend

I ordered the smallest Windmill AC for our 2nd floor hallway in our brick row house built circa 1850 in southwestern Ohio. Why on earth, you may be asking?- the summers are hot and muggy, with weeks well over 95 degrees and nights that just don't cool off.- our house is tall and narrow. 4 floors, including the stone basement, and everything is brick/stone so the heat hangs on in summer. In winter it's great, in summer you just want to lay on the floor in your swimsuit and drink Gatorade.- oddly ...

Best AC!

Would Recommend

Love my windwill. I’ve had 3 other window units before this one and it’s truly the best. Super quiet and cools down my room quickly. I work overnight so sleeping during the day, it’s usually hotter, this AC has been a life/sleep saver.
