We have two Windmill Air Conditioners, the 6000btu and the 8000btu. Love them both. Very quiet and super easy to control using the app. We had an issue with one of them and customer service was awesome! Very quick to respond to take care of the issue and followed up to make sure things were right! Definitely recommend this company!

I had a few doubts but I’m so glad I made this purchase!!! It’s so quiet, you literally forget it’s there (which has not been my experiences with other units), and I did it solo! I don’t always have help around the house so I appreciate an easy install. 10/10

I’m amazed how quiet and powerful this unit is! The last ac unit made it nearly impossible for my wife and I to have a conversation without shouting since it was so loud. The WhisperTech unit is incredibly quiet allowing us to bobonger have to shout to hear each other! Awesome product! Will be recommending to all my friends and family!

Couldn't be happier. It was delivered FAST, we ordered it when we saw a big heatwave on the horizon thinking it would take ten days to deliver something as heavy as an air conditoner and it came in two. It was easy to install, we've got it set up right next to the bed and it's not too loud to sleep next to. My girlfriend already asked me to replace the old downstairs air conditioner with this model.

The Windmill works really well and was SUPER easy install. I do wish that it was quieter when running. The advertisements really pushed how quiet it is and to me it sounds as loud as our other cheaper unit. I do like that I can turn it on using the app though! As a cat owner, it’s been comforting during these hot days that I can see the temperature and turn it on while I’m away.

I'm pleased to have a working AC... Yesterday was the first day I turned it on. The several different sounds it makes are distracting. Will I get used to them? That's why a 3 star. I was expecting a 9x quieter AC as was advertised. The staff were / are so nice... I really hope these are only the break-in period sounds. Joan

We purchased this window-air conditioning unit to supplement our central air conditioning that can't really compete with our sun-soaked main bedroom. It has been great! I cools off the room quickly at night and enables us to get a nice long sleep without being waken up by our baking room. It can be controlled by either a phone app or the remote control - which has been handy. The installation process was quick (probably less than 30 minutes) with two people and the air conditioner had really easy to understand instructions and included everything you need to install (except a drill, if you're going to drill holes to secure the air conditioner).

My Windmill Air Whisper Quiet AC was performing beautifully but developed a problem. When I reached out to the company I experienced what might be the best customer service I’ve ever had. After troubleshooting the issue with me, and with consistent and engaged communications, the representative decided that the results warranted a new unit. It arrived almost immediately, at no charge to me. And the replacement unit is performing at its peak! I categorically recommend the product and the company. It’s refreshing to be treated so well, and refreshing that a product lives up to its hype. Buy from Windmill, you wont regret it.

Not entirely impressed. My room is roughly 300sq feet and I feel as if my 8300bcu unit has to run for entirely too long for it to cool the room down. Eco mode is not the move either, takes twice as long and doesn't keep the room cooled like when it's on "cool" mode.

Hello!! We love our new Windmill A/C!!!!! It is absolutely all those great things that other reviewers described: beautiful aesthetically, easy to set up, very quiet & it cools our bedroom so that we can once again have a comfortable & good night's sleep!! Thank you to all involved in creating & supporting this more environmentally friendly air conditioner. I'm sure we will enjoy it for years to come! Oh, & one more thing: the unit arrived expeditiously once I had placed my order & I did receive several updates on the status/delivery. This has truly been an exceptional experience & purchase from start to finish! Sincerely, Kathy H.
