I did experience some issues with the first unit. However, they did replace the faulty unit and solved my issues. Love the convenience of the mobile app and how quiet the AC is while running. Customer service was very helpful and listened to my concern.

My new Windmill WhisperTech was a breeze (ha!) to install! Compared to my old unit, this new device is so QUIET. I never fully appreciated how loud my old AC unit was until I installed the WhisperTech. I would strongly recommend downloading the user-friendly app, which helped me set up and control the new unit. Based on my experience, I am going to purchase a second WhisperTech for my elderly parents.

This AC is very sleek and quiet. When people are at my house they always ask about it. This is the second one l’ve purchased to replace old window units. I will continue to do that until all our upstairs window units are Windmill units. I highly recommend this AC.

Great experience with the folks at Windmill! I was very impressed with the understanding and speed at which they handled my issue. A new replacement unit was at my door in just a couple of days. Really enjoying our new unit on this hot and humid day! Thank you.

Honestly, I was hoping that the windmill would be a step up from the AC I had prior, but I’m not convinced. The larger unit doesn’t do a great job of even cooling off my small bedroom and yet the dead of summer, so I’m thinking I’ll have to figure something else out.

The design of this AC unit is beautiful, simple, and functional. It definitely cools my space better than any other I've had. There was an issue with my original unit, but Windmill support made sure I received a replacement quickly, and working with support was a superior customer service experience. I love my Windmill!

Set up was easier than the packet said. App works seamlessly. You can set up triggers and timing for the ac to turn on and off at certain points. It does everything you would expect and more. Very quiet and effective. Cools down my living room and dining room very well and quickly.

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.

I purchased a Windmill air-conditioner a year ago and it stopped working. I contacted them and they replaced the unit free of charge and in a timely manner once I was able to provide them with all of the back up documents. I now have the new unit installed and it is sleek and quiet.

I am the proud owner of the Windmill 8K with whisper tech. First the install was a breeze… everthing included in the box! I blends so well in the living room… Uber cool design. On the tech front, once plugged in and connected to WIFI… barely a couple of minutes… easier to use than an iPhone (which is so intuitive!) I have kept my unit on since I received it… I forget it’s on because it’s so quiet! I am so happy that I am getting another unit for our bedroom… want to be cool and need to be quiet to catch zzzzzz I am not paid by Windmill to comment… if a product is great … it has to be shared. Get one or more… you won’t regret it
