Customer Ratings & Reviews

I bought this AC in early July. The AC is energy efficient, as it used most 9-10 kwh/day during the heatwave, and set at 70F. Another great feature is its low level of noise. It sounds more like a fan, rather than other AC brands. The design is pretty and its easy to install. The downside is a bit pricey but its worth the money. I'm very happy with purchase.

Not only is this the quietest air conditioner we have ever owned over the past 30 years, but it also can cool an area much larger than its rated capacity. Well over 60% more. Plus, it does it evenly, with no hot spots from corner to corner. This 12K BTU, along with one 8K BTU cools our 1100SF one level home very well and very efficently.

Aesthetically pleasing, noise level is great, not too loud for a big unit, but it does not cool my entire living room, it only makes it fresh when outside temperature is in the 70 degrees. But so far in 80 and 90 degree days it has not been efficient. I am not sure if the AC unit is not performing well due to the AC sleeve not having a lot of ventilation, or what other reason could be. I would love to return it and get a bigger unit. Maybe a 14k BTU for my 300sq ft living room but I didn’t realize Best Buy only offers a 15 day return period. So overall I cannot say it’s a bad unit but it has not worked for my space

This air conditioner was a great addition to my home. I have a very large space that this easily cooled and it was super quite. Installation was easy and it looked great in the window on both the inside and from the street. It was easy to use and to connect to my wifi and phone so that i didnt have to be home to turn it on. Its a great product and i will probably get another one next year for another room.

We have had our unit for 3 years now and it’s still working great. Had a little hiccup with WiFi connectivity this year, but it hasn’t been a problem again after relearning our network. Our space is greater than 550sqft, and I find the unit works best turned down to the lowest temp and just letting the inverter do its thing to control how much power it needs. One thing I will warn about is the vibration that comes with the inverter speeding or slowing the compressor. Newer windows are fine, but if you have an older house with old windows, it will shake them and drive you crazy.

Absolutely love my Windmill AC! It's shockingly quiet, and the level of cold it produces is impressive! Not to menion it looks beautiful inside and outside. Plus the install was so easy!

Very quiet. Easy installation! Excellent Design! Sleek looking. Cooling works ad well as any others that I have used. Does not blow right at you!

very easy to install and using the app to turn on and off the unit is a great feature. The only negative is that the fan shoots the cold air upward rather than out and across the room.

Excellent overall product. Blows cold and quiet, and even saved me a few bucks a month on running it compared to the old unit I had.

I got this a while back and after 18 months it still works like new and is amazing. Highly recommend it! It’s beautiful and is super quiet. Much nicer than my previous floor-unit that was super loud. Highly recommend!!

This was an absolute dream to install. With its clear, easy to follow instruction and extra parts designed not to challenge or confuse, making the installation process seamless. When finished the new Windmill fit my office window like a glove. And when first turning it on and within minutes the room cooled, the aptly named Windmill, made me realize why man created AC's - and Windmill were smart enough to perfected it! I thank you, my room thank you and my cats thank you.

The hype is real. other brands claim similar noise decibels but that’s laughable. Other ACs with the condensers are incredibly louder and vibrate so much it shakes the house. I can feel it in my pillow, so we returned another and got this one. It’s more money but you can tell right away where your money is going. Everything from the box to the cute packaging is well designed and has cute phrases on it like “this will be a breeze” to setup. They give you scissors to cut the complimentary foam and vanity panels. Just think about that. They’re so concerned about your install experience they eat the expense of buying all their customers scissors. The other brands don’t do that. The app is nice, it has a built in feature to tell you how much energy youre using. The remote is a clean minimalist design that’s easy to navigate in the dark. It has a stylish grill on the back that keeps you from cutting up your fingers on the metal blades. The side wings are superior quality and pre installed inside the box. It’s just ready to go. Instructions are easy. It has a QR code sticker on the face of the unit to help you get setup quickly. It’s all well done. And it’s far far quieter. Yes you hear the fan noise as others point out. But get a fan, and guess what? Fan noise. The compressor is drowned out by the fan. That should blow your face off. It’s so quiet the condenser is quieter than the fan noise. YOURE NOT LISTENING IF THAT DOESNT SHOCK YOU. Other brands condenser will rattle your teeth. I know. I just returned another one.

This AC was easy to install. Is very quiet and does a nice job cooling the 1st floor.

[Employee of bestbuy] Extremely quiet and cools my entire apartment efficiently and effectively and it’s not eye sore! The app is extremely helpful especially when on the way home from being out all day love coming back to a cool place with out having to have the ac running all day.

Best window ac unit I have ever purchased, easy install, looks great

So quite so cold. We love it. And it’s not an eyesore.

Best air conditioner on the market(in my opinion) quiet, efficient, quick to cool, and finically cold air blown up to cool from top to bottom. Awesome! Can’t go wrong with this one. I replaced all my old units with these

We bought it in 2025 and we love it. It is so quiet that we even forgot to turn it off! We are buying another one for another room. The best AC we have ever bought!!! Highly recommend it!!!

It’s quiet, efficient, and the installation kit makes this a top notch air conditioner! Love the smart features and that it can be controlled with the app and Amazon Alexa. A few days in, it began to malfunction and the internal thermostat was reading very low (like 46 degrees) which made the eco mode and being able to have it run to a set temperature impossible. The manufacturer was very responsive for technical support and they ultimately replaced the unit for us. So far the new one is working great! I hope it was a rare fluke and not a brand/design flaw. We own 2 others just like this but less btu’s and so far, they’re working great!

[Employee of bestbuy] Great unit, quiet, efficient and visually pleasing, the windmill has exceeded expectations.
