This A/C has been a great investment. It cools very well, runs quiet, although I like the white noise for sleep. I haven't had any issues with it staying connected to WiFi and the app works great. I set up an automation for it to come on at a certain time of the evening and it works flawlessly. Overall great product!

I highly recommend the Windmill AC. We purchased the 12,000 BTU unit, and it keeps our large, open-concept kitchen and living area consistently comfortable throughout the summer. It runs very quietly, blends seamlessly into the room, and is easy to control remotely through the app.

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.

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.

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.

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 because other brands were so loud. We have 2 Windmill units now, one for the bedroom and one for the living room. If we ever needed another we would for sure get it from them. We can't recommend Windmill enough.

We got an 8k BTU model which we already know is too powerful for the small 9 x 13 foot room it was put in. However, by leaving the door open the A'c does a marvelous job at cooling the room, the adjacent hallway and beyond. With simplicity of operation and it's quiet delivery of cool this A'C has my highest recommended. Now... if only they made a through the wall model!

I love my Windmill!!! Easy to install, cools great, and the internet controls are very handy.My first Windmill had a problem in summer 2025, and the Windmill support team couldn't have done a better job. They walked me through troubleshooting, and when we couldn't resolve the problem with my existing AC, they shipped me a new one.Easy to recommend Windmill!

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.

Even though I had a new HVAC system installed, I was still uncomfortable upstairs, in my 1925 home. None of my friends had heard of Windmill before, but after I read a review on Wirecutter I decided to try one for my bedroom. It arrived quickly and it was light enough that I could carry it upstairs myself, with little effort (69 y.o. female). In less than 30 minutes, with a little assistance from my teenage granddaughter, we had it installed; it quickly & quietly cooled my upstairs, beyond the bedroom I purchased it for. This is almost so easy to install that one person could do it, but due to the original, 100 year-old windows it required two people to keep the window propped open. Placing and securing it was simple. I love that the vents blow upward and not directly on me. You can hear it cycle on, but I find it no more noticeable than my central a.c. and it does not interfere with my sleep. I'm very pleased with my purchase & the comfort it provides through the sweltering summer months.
