Great ACs and Customer Service
We’ve purchased 4 Windmill ACs over the years, replacing the old ones our apartment had installed. We’ve tried several of the older and newer major brands and Windmill is easily the easily the best combination of quiet enough to sleep with, quickest to cool a room, convenient (controlling and programming from their easy to use app), and best looking inside and outside (not so important but a welcome tally). Additionally, their customer service and warranty/replacement policies are great. Windmill’s ac’s work really well consistently, but nothing is perfect—when one of our machines inexplicably stopped working they replaced it really quickly (within two days!) at no charge. It’s always nice to be able to support a small business when you can and it’s even nicer when their products a great and they back it up.Oh, and reply to the owner’s, Mike’s, emails, he’ll respond and help out when needed!Very, very easy to recommend Windmill.

Fantastic Window AC Unit
This item is beautifully designed and works well. I particularly liked how it is quieter than my old window AC unit. The install was easy as well. Great AC unit, best I have bought.

Best A/C we have ever had!
Living in Manhattan, we have always had in-window air-conditioning that has worked to varying degrees of success from other brands. Windmills AC unit worked as expected, and the integrated app was extremely useful and user-friendly. It wasn't hard to install by myself. We ended up getting a second for our spare room shortly after testing the first. Living through the extreme weather of New York didn't feel like a challenge at all. Highly recommend. Oh, also, their customer service is phenomenal in my experience. There was an issue with our second unit, but once I shared the video of the noise it was making, they rushed shipped a replacement. Tryuely felt like they cared about their brand.

Love our Windmill!
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.

Windmill AC_Great Customer Service!
We have used the Windmill AC for the past two summers to combat the northeastern heat and humidity. After a summer of successful use, our unit’s compressor unexpectedly stopped working during the second summer. The Windmill AC team helped trouble shoot the issue and when it became apparent that the issue couldn’t be solved, quickly sent out a replacement unit. They were absolutely wonderful to work with! We were able to engage with real people the entire time. They made the process a breeze- pun fully intended! ;-) Within a few days, we had a new unit in place to combat the summer heat! The unit keeps our place cool, is a quieter than any we have ever used (and we have used them all!), and isn’t an eyesore! Wins all around!

Sleek and effective!
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.

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!

Best of the best
I have purchased 2 windmill window a/c units and am extremely pleased with them. The app functionality makes the unit truly impressive and well rounded. Creating schedules makes operation a breeze and lets me run the unit efficiently. When they are running they are very quiet compared to a traditional window. Having the fan blow up into the room instead of straight out helps cool the room quicker as well. Love the product, highly recommend.

Quiet, efficient, and not an eye sore. This is the air conditioner I’ve been looking for. Plan to get another for the upcoming summer.

Happy to have purchased
I love my Windmill AC. I recently added the side panels. They help w the look and also help w the cold drafts when it’s not cooling the room. Quiet and love the magnetic cover when it’s time to clean the filter.

Great A/C
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!

Cool and Quiet, Fresh and Clean
We love Windmill so much, we retired our perfectly good Frigidaire air conditioner for our kids’ room because we wanted something quieter, more intuitive and energy efficient after we bought our fist Windmill for our dining room several years ago and it cooled down the whole house. Saving for the next one!

Great AC
We’ve loved our windmill ac units and air purifier! They’ve worked perfectly. We’ve had our air conditioner units for two summers now. I love the look of these products and that they aren’t eye sores like most others. They are simple to use too!

Best AC unit
I’ve owned a competitor u-shaped window unit and love the Windmill more! The design is perfect and doesn’t stick out in our living room. It was incredibly easy to set up and I love that you can control it via your phone when you aren’t home. I recommend this unit to everyone.

Great cooling solution
I love my window unit. I have a Cape Cod, and the upstairs bedroom is too hot to sleep in during the summer. It also isn’t a ton of square feet. The Windmill AC I bought is the perfect size. It is sleek, effective, and so efficient that I don’t notice a huge difference in my electrical bills in the summer. I am really satisfied with it.

Great AC unit with smart features and easy installation!
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!

I love Windmill!
I have 3 Windmill AC units, they're all quiet, efficient, and a breeze to install! Replaced older (not too old) traditional window ac units, these inverter units are significantly quieter, and cost effective. We can sleep at night with the unit going in our bedroom, and the smart app makes using them a breeze.Thanks Windmill!

My favorite. Works great in my mid-size NYC apartment. It's also very functional and its not loud at all. It looks also way cuter than other models.

We love (all three!) of our Windmill ACs. Nice to look at and be around, and doesn't blast the cold air directly at whatever's in front of it.

Pretty on the Outside (and inside)
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!
