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!

⭐️⭐️⭐️⭐️⭐️

This window AC is a total game changer. It cools the room quickly, runs quietly, and keeps a consistent, comfortable temperature even on really hot days. Installation was easy, and it feels sturdy and reliable. Definitely worth it, highly recommend!

Amazing Service

The claim team is amazing and helped me greatly. The replacement unit is in place and created a quiet and cool space in our room over the garage! I could not be happier.

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!

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!

Great AC and great Customer Service

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!

Amazing

I did a lot of research before buying a window AC. Originally, I wanted one of the U-shaped window ACs that have been popular in recent years. When they all started being recalled over mold issues last spring, I decided to go with Windmill instead because of the inverter technology. I'm so glad I did. I have the Whispertech 8k BTU and it keeps our queen size bedroom freezing cold in the summer. It's so quiet, and it was very easy to install. I like how sleek it looks. I got a second one for our guest bedroom and in the summer when both are on and the doors are open, our entire 1200sqft apartment stays really comfortable. Electric bills were entirely reasonable and I can't say I noticed any difference from having them. 10/10.

Looks Great, Works Well

The Windmill AC actually looks good in your space, it's easy to install, and the app control is genuinely convenient. I definitely found it useful to control from bed. Cooling-wise, it does a solid job for small to medium rooms and stays pretty quiet! I've experienced other window ACs and they were super loud in comparison. Overall, I am glad I went with this one for my small NYC apartment

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.

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.
