great customer service

I had a 10,000 btu unit that developed a startling rattle due to the compressor being too close to something metal and all it took was a few simple emails w/ a video and photos attached and they handled it from there.The new unit itself is aesthetically pleasing and is quiet to say the least. If you're used to the hum of a standard window A/C, this thing will make you wonder if it's even on. I worked with Mike, Lisbeth and Francesca - all of them were very receptive to my situation and quick to reply with help. Thank you team for all you did in making this new customer very happy.

We’re very happy with our Windmill AC. While one unit failed after just over a year, we consider it an aberration and Windmill was so good about backing their product with a replacement.

Great Product and Fantastic Support

I love the super quiet AC unit. Perfect for my home office-quiet enough for me to hold Teams meetings. Had an issue with the original unit, but the customer support was amazing. Followed up quickly and after just a few questions and uploading a quick video, they replaced the original unit. So impressed with the support. And anyone that comes into my office space is amazed at how quiet the unit is. And I love how I can control everything from the app. I highly recommend the product and the company/support behind it.

Best Window AC Ever—Stylish, Quiet, and Powerful!

I couldn’t be happier with my Windmill AC! From the moment it arrived, the setup was unbelievably easy—out of the box and cooling within minutes. The design is sleek and modern, blending right into my home without the clunky look of traditional window units.Performance-wise, it’s outstanding: whisper-quiet, powerful cooling, and the airflow feels cleaner thanks to the built-in air filter. The app control is a game-changer—I can adjust the temperature from anywhere, even before I get home, which makes it super convenient.What really stands out is the attention to detail: the packaging is eco-friendly, the installation kit is foolproof, and the customer service is top-notch. It’s clear Windmill thought about everything to make this experience seamless.If you’re considering an AC upgrade, stop searching—Windmill is worth every penny. It cools beautifully, looks great, and feels smarter than any AC I’ve owned before. Highly recommend!

Super quiet and excellent customer service

This is a very quiet A/C and I'm surprised that the major manufactures are not producing the same technology. It's so quiet that any little noise will make one wonder. So a couple of days after installing, I noticed a chirping sound and contacted customer service to make certain this is normal. (still was quieter than a traditional unit). It was determined that the sound is not normal and must have suffered shipping damage. Without hesitation I was sent via express delivery, another unit. This is quiet enough that I had to wonder how it could cool, but it does an excellent job of that as well. Our sofa is in front of the A/C and it doesn't bother at all. The air blows up, not out. I love the wifi feature and the app is simple without complicated graphics. This outfit knows how to do it and I am a 100% supporter! I'll be buying more for other rooms in our 1920's Washington DC Co-Op

Recently had trouble with my 8000 icing up. Contacted Windmill service and they were very helpful. Gave me some ideas to try to fix the problem., none worked. They decided to replace my unit even though it was out of warranty. Cannot say enough good things about this company and its products.
