Happy with my cool 😎 new Windmill air conditioners !

Would Recommend

I bought two Windmill air conditioners in May. They installed easily with the excellent illustrated instructions, I was pleased with their performance all summer long. So pleased, in fact, I purchased another air conditioner for my Granddaughter! Since I live in PA and it’s December, the heat is on. Very pleased with my purchases. Thank you and Happy Christmas 🎄 PS: sorry, I don’t have any pictures.

Great for our bedroom

Would Recommend

We like to sleep cold so bought this to chill our bedroom without having to adjust the thermostat for the whole house. It's perfect, quiet, and was supereasy to install.

Great AC and great Customer Service

Would Recommend

We purchased two Windmill AC - 8K BTU WhispeTech air conditioners and love them! As a senior, the customer service team was helpful and kind in answering my questions about installation and care. The units not only look great but also are designed to be able to stay in my windows over my Vermont winter seasons eliminating the need to find others to help me remove and then reinstall the units each season.When my other older units need replacing, I intend to purchase more Windmill units!

High quality and peaceful

Would Recommend

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 bedroo...

Great machine - even better customer service

Would Recommend

Doesn’t look - or perform - like any other window unit. Stay sleek and cool with this low profile, remote-controlled unit. And the best part is the customer service team ready to help you out if any issues arise. When I had difficulty the team went above and beyond to find a creative solution. You don’t get that level of attention when you’re dealing with a huge company. They take pride in their products and in their service.

Windmill 10, 000 BTU

Would Recommend

I purchased a Windmill air conditioner and I’m genuinely impressed. First, the sleek, modern design instantly upgraded the look of my space. It’s also almost silent — a huge difference from my old, loud unit that used to drown out my TV. Despite the quiet performance, it cools the room incredibly well.My favorite feature by far is the app. Being able to turn on the AC before I get home — especially when I’m coming in hot and carrying groceries — is a game changer. It’s convenient, efficient, and...

Gamechanger and I now have 3 units

Would Recommend

Finally, a thoughtful and well designed A/C until that doesn't sacrifice form or function. On top of it, their customer service is second to noneIf I were to offer a design suggestion, consider having a magnet in the remote so that it can stay with the unit

The Rolls Royce of ACs!

Would Recommend

You heard that right! This is the Rolls Royce of ACs! Why? Because it is quiet, cool-looking and just fits seamlessly into your life style or it might actually upgrade it! I’ve had several ACs in the past for a large room and this is the first one that actually cooled the whole room to my liking. Not too much or too little. Perfect just the way I like it! I bought their fan and their air cleaner because I’m so impressed with the AC. This is a quality product hands down! RUN, don’t walk, to order...

Bought Two Units--Love Them Both

Would Recommend

I bought the original 6BTU unit for my bedroom and the super quiet 10BTU unit for the living room. Love the remote option. It's great that you can turn them on before you get home. They are quiet and efficient! I highly recommend them. Oh, and customer service is great.

Great AC for My Apartment

Would Recommend

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.

The BEST AC!

My windmill AC works insanely well. It surpasses other AC units in quality, functionality, and aesthetics. Additionally, the Windmill team is incredibly helpful and super easy to get in contact with!

AC

Love this! Being able to control from my phone has helped keep my apt cool for my dog during the summer months when I am not home!

Excellent AC!

Would Recommend

Our windmill AC was a life (and sanity) saver this summer! It kept our home cool and was remarkably quiet for a window ac. Also want to thank Mike and his team for their quick responses when there was an issue with the first unit we were sent. They made what would normally be a stressful process very easy. Very happy with this purchase!

The whole package

Would Recommend

Let’s face it, air conditioner’s are an eye sore. However, Windmill maybe the best looking of them all - it blends in quite well as you can see in the photo. They provide these adjustable side patches which block out air, and also serve to hide the ghastly side panels. Setup was straightforward, did it in 15min. Unit works well, quiet and cools my living room quickly.

Awesome Air Conditioner

Would Recommend

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.

Best air conditioner

Would Recommend

I’m a voice over artist and work in a hot booth in the summer and being able to have this running outside my booth while recording is amazing. It’s that quiet! I’ve never had an air conditioner this quiet before. Makes living in NYC in the summer so much more comfortable. It also saved us money on our electric bill

Best window AC ever!!

Would Recommend

Quiet, easy to install, keeps perfect temps, low efficiency and doesn't get moldy. Loved the 2 I had so much I bought a 3rd.

And a bag of chips

Would Recommend

I now have three units covering two homes and they are everything I hoped they would be -- and more! Quiet, effective, and convenient (with device management through my iPhone), I have recommended these many times.
