Happy with my cool 😎 new Windmill air conditioners !

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.

aesthetic, quiet, and powerful

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.

Excellent AC!

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 BEST and easiest AC I've ever installed!

I bought my Windmill AC from Home Depot this summer, and it has exceeded my expectations in every way. Installation was simple, and I really appreciate the thoughtful design—(they even included a great pair of scissors to assist you with the installation!) especially the rounded edges and clean, modern look that fits perfectly with my decor.The unit cools my room quickly and evenly, and it's impressively quiet compared to other window ACs I've owned. I love that it connects to Wi-Fi so I can control it from my phone, and the app is super easy to use. It's energy efficient too, which helped keep my electric bill lower during the hottest months.Overall, the Windmill AC has been one of the best home purchases I've made all year—stylish, smart, and powerful. Highly recommend it to anyone looking for a reliable and quiet cooling solution! I went back and bought two more!!

Bought Two Units--Love Them Both

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.

Super quiet and does the job!

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!

Best AC Unit I Own

Hands down the best AC unit I own.I have multiple window units from different brands throughout my home, and the Windmill is easily the standout. It's the quietest unit I've ever used while still being extremely powerful and efficient at cooling the room quickly.The difference is noticeable the moment you turn it on, no rattling, no loud compressor noise, just consistent, strong cooling. Compared to my other units, this one feels more premium in both performance and sound.If you're deciding between brands, this is the one I'd buy again without hesitation.

Excellent AC Unit!

Brilliant design. Fantastic construction. Super quiet. Easy to operate right out of the box. Family-owned business. I purchased three to replace older, heavier units that I was no longer able to change out every season. Top notch customer service and communication. Wouldn't consider buying anything else.

Hands down the best window unit we've ever owned!

We have had so much bad luck buying ac units in the past and despite storing them as directed in the winter, they always seemed to die on us. After hearing about Windmill and reading reviews we took a chance on this one, and it was worth every penny. It's by far the most efficient, most quiet, and aesthetically pleasing ac unit we've ever had. It kept our home cool and comfortable throughout the spring and summer. And it was so easy to install and use.

Quiet and convenient

We purchased the windmill air conditioner for our toddler's bedroom. The air conditioner is exceptionally quiet, which significantly contributes to the amount of sleep she gets throughout the night. It's very convenient that we can leave it hanging on the window during the winter months, which makes my life easier since I don't have to take it down every year.
