Easy AC ever

Would Recommend

This AC was so easy to set up. No ******** the freaking flaps on the side and having them fight with you. This AC took about ten minutes to install from box, to window, to turning on.

Very happy with the ac unit

Would Recommend

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 fo...

A perfect AC

Would Recommend

I am impossibly picky, so when I say my Windmill AC is perfect, I mean it. It is shockingly simple to install, has a super-sleek design, is energy efficient, and despite its outstanding cooling power, is whisper quiet to live with in my one-room studio apartment. It also comes from a small business, not a corporate behemoth, with a refreshingly personable approach to customer service. All that to say, I highly recommend the Windmill AC over all the rest. It really is perfect — even if you are im...

Best Window AC I've Ever Had

Would Recommend

The Windmill is the best window AC unit I've ever had. It looks great, is easy to maintain, has a good mobile app to control it remotely(not required, but useful), is easy to maintain, relatively quiet, and my favorite feature is that it blows cold air up, not out, so placing it in a window near a chair, seat, bed, etc. is much more comfortable than traditional window units. If you need a window AC, I'm not sure there is a better one on the market!

A life saver

Would Recommend

This is such a top notch air conditioner it’s unbelievable. The app makes it so convenient to use and turn on before I’m getting ready for bed or whenever I get home. Also the air blowing up instead of out genuinely cools the room so much more. I have a very large master suite and it cools it down so well. Plus the look of it?? Amazing. It’s so seamless and not the bulky and ugly window units you are used to.

The best AC on the market

Would Recommend

I bought this AC through a recommendation from my sister , she has three and work perfectly. When I got my apartment, I didn’t think twice and order one for me. Very quiet and looks modern. Love this product and super recommended. Great customer service. It was an easy summer in NYC because of this amazing AC.

Great ACs and Customer Service

Would Recommend

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. Windmil...

Fantastic Window AC Unit

Would Recommend

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!

Would Recommend

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 ...

Love our Windmill!

Would Recommend

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!

Would Recommend

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...

Sleek and effective!

Would Recommend

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!

Would Recommend

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

Would Recommend

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.

This AC works great but it won't bring my son back.

Great choice!

Would Recommend

I love my Windmill AC. It looks so much nicer than most A/C’s, it can be co trolled by my phone, and it cools quickly! The only down side is that it would vibrate at certain points when running, but thst was easily rectified by placing a wedge in the window (I used a piece of wood cut to size). It gave enough pressure on the window to stop the rattle.

These are by far the best ACs available in every way — the design, how they function, the app, the customer support, all exceptional.
