Windmill Inverter Window Air Conditioner with WhisperTech

I love my Windmill! It's beautiful, efficient, and quiet.

I saw this AC on a news site, and thought it sounded like a great little machine. Now that I have one in my window I can report the Windmill is quiet, easy to control, and keeps my rooms nice and cool. No more roaring when the compressor kicks in. I love it!

Why didn't I buy this sooner? Truly quiet and cools my apartment quickly.

Works great to cool our large space! Sleek design, easy to install, super quiet but has a fan if you need some white noise.

The AC saved me money this year which was already great but it started to make an odd noise and I was sent a new one no questions asked. Just really great customer service all around.

The thoughtfulness of the design and installation process was fantastic! Little things like them including a pair of nice siccors was impressive.We had a problem with our unit's fan rattling and after working with customer service (who were great) and sending them videos they replaced it with no problems.My only complaint was that they should allow for larger video sizes. 10 MB is way too small to capture the issue.

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.

The design of the WindMill air conditioner is advanced , leading to a quiet- running, highly effective system. The visual presentation is also very nice .It is a very reliable system - highly recommend.Customer Service is wonderful be it for setting up the AC out of the box or getting replacement air filters- thank you

Very quiet and well designed, we did have a problem and the customer support was excellent!

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

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!

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.

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.

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.

New unit was not running right. I sent a video and was contacted within 24hrs and a new unit was shipped right away. Great response time!

This AC unit is unbelievable. It’s quiet its energy efficient and maintains temperature. Great product!

Easy to install, did make a grinding noise when first starting up. Quiet now and cooling our room nicely.

This AC is sleek and effective. We have two of them and they cool the whole apartment. When one of them malfunctioned gathering ice inside, we reached out to customer service and they resolved the issue immediately by sending a replacement! The new one is working great!

We are very happy with the windmill! It’s pretty quiet and that’s one of the reasons we made the purchase!
