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.

Love how quiet it is and how aesthetic looking it is in the window. But the remote control, at least to me, doesn't work as well as it should from about a 12 ft distance. I have to keep moving it many many times to change speeds or temperatures and a lot of times I need to get up and go over and do it myself manually, or get closer with the remote. The remote leaves a lot to be desired. Other than that, it's a great air conditioner. There were no instructions in the package for different modes on the remote or exactly how to use it. That's my only complaint.

Easier to install than other brands despite the instructions saying it would take 45 minutes. My wife does not like light in the room at night and this air conditioner is perfect as their is very little light. The windmill air conditioner is quiet and that helps when trying to go to sleep. Best air conditioner we have ever purchased.

I have just purchased my second Windmill AC. As I am 79, installing on my own was not an option. Thanks to my wonderful super, who did the installation, I had cool air in two rooms of my apartment in 15 minutes! Windmill ACs are nice looking, work extremely well, and a great value.

This is the 3rd purchase of your A/C and I must say that the main reason for purchasing them is because of their quietness and they are quiet. I like the idea of having them connected to my phone it makes it easier to turn them off or on or adjust them without having to physically go to each room. As a bonus they do look a lot nicer than our other ones that where replaced .

I wish I could give them more stars! I had a technical issue with my unit and after troubleshooting it via email for 30 min I had a confirmation number with a brand new unit coming my way!! Insane costumer service!! Aside from that the unit itself is amazing! It sits in our living room so it’s been so nice to be able to hear the TV and not have cold air blowing directly on you. Quit and efficient machine!

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 purchased my Windmill A/C unit and installed as soon as it got here. It is so quiet when it’s running you hardly know it’s there. It’s small in size and for the windows perfect. It took my daughter and her fiancé less then 30 to install. I love it.

Beautiful and quiet! Had been lusting over it for a year and finally pulled the trigger - the phone control is huge! I can turn it on on my way home from work or confirm if I turned it off when I leave. Wifi wasn’t the easiest to enable as I had to reconfigure my settings but still well worth it.

After doing extensive research on Windmill, I am extremely happy with my purchase. All of the reviews from some of this country’s top publication rated Windmill very high. Compared to other air conditioners I have owned, Windmill is by far the best in relationship to noise level and ac output. I am very happy and fortunate I came across Windmill during my extensive research on window air conditioners.
