Very happy with the ac unit

I'm very happy and impressed with the Windmill air conditioner. I installed in our short term rental unit and it excels at all levels. One, it looks very good on both sides. Over the years I've had a number of units in the window. Some are aesthetically tolerable from the inside but all, up until the Windmill unit, are an eyesore from the exterior. Two, its functionality is elegant - straightforward and intuitive, and buttons are responsive. Three, the remote is attractive - which is a rarity for air conditioners.Four, the motor and fan is quiet but powerful - cooling the space quickly.And five, it seals very well around the window, with some very well thought out designs for air sealing and aesthetics.The unit is a little pricey compared to others but worth the cost. I plan to buy more for our house when the time comes.

Happy to have purchased

I love my windmill air conditioner. So quiet and efficient. The cooled air blows out from the top of the unit . The magnetic cover is a genius idea when cleaning the filter. Appealing to the eye and the side cover panels really add to the attractiveness of the unit . I'm planning on purchasing another in the future.

Best A/C I've ever had!

This A/C unit is a powerhouse. It has turned my living room into the perfect place to be on a 90+ degree day. Within an hour of turning it on, my room is nice and cool and ready to relax in. The best part about it is that I can turn it on and off remotely from anywhere, so when I've had a long day at work, I turn it on when I am headed home and the room is perfect when I arrive. I would highly recommend it to anyone!

The Upgrade of a Lifetime

My husband and I purchased two Wind units last summer after our (not so old) units from a certain brand experiencing awful mold issues were deemed unfit for use. We are so distraught and really put time and effort into shopping for replacements. When we found Windmill, we knew we found a brand we could trust. Installing the units was a breeze - I did it 99% by myself, with a quick hand from my husband to support them before locking in. The custom side panels are amazing! Create a chic and clean look that feels very well insulated. The whole profile of the units is sleek and designer looking. Operation-wise, the units are whisper quiet and cool extremely efficiently/quickly. We will be moving homes this summer, and I'm honestly excited (something I never thought I'd say) to get our units in the new windows! Windmill is an changer when it comes to window ACs.

⭐️⭐️⭐️⭐️⭐️

This window AC is a total game changer. It cools the room quickly, runs quietly, and keeps a consistent, comfortable temperature even on really hot days. Installation was easy, and it feels sturdy and reliable. Definitely worth it, highly recommend!

Amazing Service

The claim team is amazing and helped me greatly. The replacement unit is in place and created a quiet and cool space in our room over the garage! I could not be happier.

Great AC for My Apartment

I bought the Windmill AC for my apartment in NYC, and it's been perfect. It cools my space quickly, runs quietly, and looks sleek—way better than any other AC I've had. The app is easy to use, and installation was a breeze.Definitely recommend it if you need something reliable and stylish without the usual noise.

High quality and peaceful

We have a Windmill AC we purchased this past summer. We live in an early 1800s farmhouse and needed something that could keep up with the heat and not drown out the space in compressor noise. The Windmill AC is exactly that. We put it in our dining room and no one knew it was running. It is so quiet and for being in our old style home with little insulation it runs efficiently and effectively. We're slowing understanding the environment of our old house and we may get another for our main bedroom. Right now we're using a few mobile AC units (along with the Windmill AC). The Windmill was a welcomed addition to our cooling needs.

Awesome Air Conditioner

We got this for our bedroom earlier this year because the one in our living room wasn't powerful enough to cool our room down the hall. This cooled our room so quickly, and it was much quieter than the one our apartment provided. I love that you can use the app to set it to turn on and off at specific times so we wouldn't need to worry about our cats being too warm during the day.

trying something different

I saw this AC on a news site, and thought it sounded like a great little machine. Now that I have one in my window I can report the Windmill is quiet, easy to control, and keeps my rooms nice and cool. No more roaring when the compressor kicks in. I love it!
