So Far So Good

Purchased this A/C in July and it’s been excellent so far. Fast delivery, straightforward installation, and very smooth, quiet operation. The app is well designed and makes controlling the unit really easy. Would definitely recommend.

Amazing

Would Recommend

I did a lot of research before buying a window AC. Originally, I wanted one of the U-shaped window ACs that have been popular in recent years. When they all started being recalled over mold issues last spring, I decided to go with Windmill instead because of the inverter technology. I’m so glad I did. I have the Whispertech 8k BTU and it keeps our queen size bedroom freezing cold in the summer. It’s so quiet, and it was very easy to install. I like how sleek it looks. I got a second one for our ...

Looks Great, Works Well

Would Recommend

The Windmill AC actually looks good in your space, it's easy to install, and the app control is genuinely convenient. I definitely found it useful to control from bed. Cooling-wise, it does a solid job for small to medium rooms and stays pretty quiet! I've experienced other window ACs and they were super loud in comparison. Overall, I am glad I went with this one for my small NYC apartment

Worth Every Penny

Would Recommend

I love my Windmill AC. It was easy to install (though did take two people--its heavy) and continues to look gorgeous six months in. It has made my 100-year-old top-floor apartment livable in the summer, without sacrificing aesthetics. I love that I can turn it on from my phone when the heat picks up unexpectedly in the daytime, and know my cat won't be uncomfortable. I recommend one to everyone I know!

Quiet, Stylish, and Easy to Install

Bought my second Windmill AC this summer and am so happy with both! Love the easy functionality of the app, and I really appreciate how easy they are to store off-season.

Super quiet and excellent cooling!

Would Recommend

We bought two of the 12k btu units when our mini-split died and was going to cost 9-10k to replace. I was skeptical at first because the reason I went with the splits in the first place was I could not stand the sound from window units....especially since the window it would in was right next to me when I watch TV. I was pleasantly surprised that these units are better than 50% quieter than other units I had before the splits. I was very nervous going back because the splits were virtually silen...

Have bought 3 over 3 years to replace my old window ACs so that I have them throughout my entire house. All three work like brand new and are super cute.

Fantastic quality, great look!

Would Recommend

First AC I bought in awhile and it's a perfect buy. We moved into our first home and wanted to upgrade from our decades old ugly, loud, AC units.We bought a windmill AC which looks great, is quiet, has a great application.We loved it so much we bought an air purifier as well!

Loving our Windmill ACs in our old home!

Would Recommend

We have an old, New England Victorian home. We got quotes for installing a cooling system through the attic that would have cost upwards of $20K that we do not have! Windmill was the obvious next best solution and we are so happy with our ACs. They look pleasing to the eye and are not an eye sore, run great provided you follow the filter cleaning instructions regularly, and can even stay in place during the winter. We love that they are designed with winter in mind - we don’t have any room to st...

Great Air Conditioner and Beautiful Too!

Would Recommend

Love my Windmill Air CONDITIONERS! I purchased 2 two 8K BTU Whisper Tech ACs last year. They work terrific, look beautiful and can safely and efficiently stay installed over my cold New England winters. Great purchase!

Fantastic AC, fabulous customer service

Would Recommend

I love my Windmill! When FedEx delivered my unit, they left it on its side in a damaged box, and the AC had a rattle that wouldn't go away. I was wary of Windmill's email-based customer service system, but Eddy got back to me immediately and emailed back and forth with me in real time until he'd determined that the unit had to be replaced. FedEx damaged the replacement unit too, and Eddy and Windmill arranged for yet another replacement. The third one was delivered safely and works perfectly, no...

Hands down the best window unit we’ve ever owned!

Would Recommend

We have had so much bad luck buying ac units in the past and despite storing them as directed in the winter, they always seemed to die on us. After hearing about Windmill and reading reviews we took a chance on this one, and it was worth every penny. It’s by far the most efficient, most quiet, and aesthetically pleasing ac unit we’ve ever had. It kept our home cool and comfortable throughout the spring and summer. And it was so easy to install and use.

Love my windmill!

Would Recommend

I live in an old 1950’s cape cod style home that doesn’t have great insulation and that has an upstairs that is almost always the temperature of outside. This summer our ac also broke. We used a windmill in our main living area and in our upstairs bedroom and they were an absolute game changer. I love that they’re sleek and quiet, they don’t take up much space but do an incredible job and keeping the space cool. The app has app been helpful in that I can check the room temp from home or away and...
