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.

I purchased not just one but two Windmill air conditioners. After my first purchase of a 12K BTU WhisperTech for my living room, I followed with an additional purchase of a 10K BTU WhisperTech for my bedroom. They are super efficient and oh so quiet. Also they are so good looking too. So happy with my purchases. Highly recommended.

This window unit has been a lifesaver in an old house without AC. I love the automatic settings on the app so that I can turn it off or on remotely and save on energy costs when I'm not there. I like using the fan setting at times overnight for some white noise as well. It was easy to install by myself as well

I live in a small apartment in NYC — the Windmill AC was perfect for my shoebox-sized room. I loved the fact that I could control it remotely to cool down my room before I got off the subway, and I found it incredibly intuitive to use. I'm moving to a larger apartment in a couple months and looking forward to getting a second one. Also, my roommate's cat loves to sit by it too!

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!

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.

I've been using windmill ACs for several years now, and a major plus is that I can control the unit via the phone app even when I'm not home. Not only does it work well, the design of the AC looks beautiful in my apartment. I used the original model (6k BTU) for 3 years, but after moving last year I decided to get the new WhisperTech model (8k BTU) and am super impressed with how much quietier it is and how quickly it cools my home. The customer support has always been fantastic as well!

This AC unit was so easy to install and was so quiet that I ended up buying a second one for my son's room. I bought the smallest one for his room and its so quiet and perfect for his small nursery. Also that fact that I can control the AC unit from my phone helps when the temperature changes drastically in his room and I don't have to sneek into his room while hes asleep. Wonderful unit!

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 more attractive than most window air conditioners, both inside the house and outside. Not an eyesore!It's straightforward to operate, and I found the smart/connected functionality to be quite welcome and useful. Overall, it's worth the investment, easy to live with, and even easier to recommend!

I have 3 Windmill AC units, they're all quiet, efficient, and a breeze to install! Replaced older (not too old) traditional window ac units, these inverter units are significantly quieter, and cost effective. We can sleep at night with the unit going in our bedroom, and the smart app makes using them a breeze.Thanks Windmill!
