Much louder than expected. Looks great. I thought this one had whisper tech but it does not. Aesthetically this AC is very neat and clean and nice looking particularly for a window unit.

We got two Windmill units in 2024 and have had nothing but a great experience with them. They are easy to install, look beautiful and are much quieter than our old unit. Now we don't have to turn the A/C off to hear the TV anymore! Many people in our building also have them. I highly 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!

This AC unit was so easy to install and was so quiet that I ended up buying a second one for my son's room. I bought the smallest one for his room and its so quiet and perfect for his small nursery. Also that fact that I can control the AC unit from my phone helps when the temperature changes drastically in his room and I don't have to sneek into his room while hes asleep. Wonderful unit!

Had a few AC's over time and when it was time to replace I tried checking out the Windmill site.Picked out one that looked good and small for a NYC apartment with and was fair priced.When we got it, getting it into the window was super easy, and it looked great but let's turn it on....When this was going on NYC was in the middle of a heatwave, so we got it just in time, and once we turned it on we wore pleasantly surprised at how quiet it was and even better, during a heatwave how fast we wore cool and comfortable.So if you're thinking of getting a Windmill from me it's an easy “YES!”

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!

While all of my neighbors have unsightly and rickety window bangers, my sleek Windmill sits gracefully perched in the window. I am stopped on the street with fingers pointing up above, "What is that??" I proudly declare, "She's a Windmill" Before you spend the money on mini-splits or central air, give the Windmill a try!

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.

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 Air and I can report that it runs like a charm.J Lotus

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!
