Best ever!!

Would Recommend

After having four other air conditioners, none of which did the job or they died after a few months, we discovered Windmill and what a gift THAT was! We’re still amazed at how beautifully it works. The cooling is terrific, it’s very quiet and we simply could not be happier! Plus, it looks wonderful!

Great air conditioner!

Would Recommend

Bought a Windmill for our bedroom window to augment a dying central air system this past summer. Very happy with our choice!Installation is easy. If you’ve installed other air conditioners, you can definitely install a Windmill. If you haven’t installed an air conditioner before, the Windmill is very approachable and the very clear instructions take any guesswork out of the process.This is a design-forward product, and I do appreciate the thought that was invested in its appearance. Certainly mo...

Attractive window AC

Would Recommend

This AC looks so much better than any traditional unit we've had. It works extremely well and cools a large, open area of our home. I wish I could switch every window unit we have with one of these!

Great AC unit

Would Recommend

This unit has been perfect! Simple install, user friendly app, quiet. In a room with 12 single-pane windows, 6 of them south facing, it kept it cool in the Southern summer. Customer service has also been great! The winter cover work well too.

So far so great

Would Recommend

My ac unit from Amazon stopped working in the middle of a heat wave so I bit the bullet and spent the money on this. I’ve only been using it for one summer but it’s been worth every penny so far, it’s nice and quiet and cools my apt way better than the old unit ever did. I really love being able to control it from my phone and turning it on before I arrive home. I’m really hoping it lasts years since it was so expensive 🤞🏼

Excellent AC Unit!

Would Recommend

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.

Great to be able to control remotely!

Would Recommend

Looked into several different ACs for my apartment and Windmill was the cleanest looking and most convenient. The app is simple to use and I love being able to turn it on remotely. Be sure to purchase the correct AC BTU for your space though. I was concerned the temperature censor wasn't reading accurately. But that was my fault given I was trying to cool a large space with a low BTU. Windmill customer service was very helpful in trying to help me regardless.

Great product - plug and play!

Would Recommend

Have owned the AC for about a year and it got me through a harsh NYC summer without a hitch! I’m also very sensitive to dust and mold and noticed an immediate difference in my sinuses with the product. Highly recommend!

Best AC out there

Would Recommend

I purchased 2 WhisperTech ACs for my small NYC apartment after seeing how well the unit worked in my daughter's studio apartment. I am very happy with the units. They are quiet and I really like that they don't blow air out the front of the unit, but from the top! My bedroom unit is fairly close to my bed and I don't have the problem of feeling the cold air while I am sleeping. This is such a welcome change to the older unit I had that was loud and blowing constanting in my face! And in living r...

aesthetic, quiet, and powerful

Would Recommend

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.

Relatively easy to install, very quiet, and cools the room down.

Quiet and convenient

Would Recommend

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.

Best window AC ever

Would Recommend

I have had many window ACs over the years and this is by far my favorite. It is easy to install, quiet, easy to clean, nice features and attractive. I will definitely be replacing one of my old ones with another Windmill this coming summer.
