Got a unit that was noisier than advertised, likely a shaky compressor. Messaged Windmill customer service. It was the greatest customer service experience I have ever had! Every response was within minutes. Within a day they had shipped me new unit. It works great, quite quiet. A+

The set up was super easy and love that it came with a piece you can cut to fit your window perfectly on the sides. I bought the small one just for my bedroom but will be buying the bigger one to replace the one in my living room. Love that they offer to remove & dispose of your old one for you!!

I love my Wimdmill air conditioner! It’s so quiet and it cools the house beautifully. The unit was easy to install. It came fully assembled with great instructions in case I needed some help. Customer service is also 5 stars. I would purchase this product again without hesitation.

We haven’t really put the A/C through its paces yet. But, I wanted to write a positive review about the customer service. When I installed the Windmill (6000) in a small bedroom window, the first night it was really loud. In contrast we have the Midea U shaped A/C in our front window. That is really quiet and I love that A/C but it was a hair too wide for the bedroom window screen frame. So, I opted for the Windmill which just fits. So, yes, 1st night. Loud. Like an airplane turbine winding up. I emailed them the next morning saying I wanted to return it (I planned to replace with a Midea and I would just force the Midea into the frame). They emailed me back so fast. I sent them a video of the A/C operating. Within a day and a half we had a replacement shipped by a local delivery company. It was MUCH quieter than the first one. And, so far it works great. -I like in the bedroom that the air blows upwards. I have a fan clipped next to it if I want to blow it my way. -So far gets the room cool fast. Though it hasn’t really been challenged by a heat wave yet. -I like the app function saying how much power you used. -There’s a couple tweaks in the app I wish could change. I would like to know when/if the A/C is running. I want more control for when I’m sleeping. It’s not clear cut as far as scheduling. Basically, I want the A/C to turn on when the room goes above a certain temperature (when I’m sleeping) and turn off when it reaches that set point. And, I want a daytime setting (I’m not in the bedroom and it doesn’t need to run at the same temperature parameter). It’s been weirdly difficult to get it working this preference. Maybe I’m just not understanding. But, the scheduling part feels clunky or not fleshed out in a way I would like to use it. We’re not typical A/C users. We prefer it not running. Eco mode is annoying because it fires up the fan intermittently. If I set it to “cool mode”, it just runs and I don’t want that. I only want it to run/turn off minimally in a way where I don’t lose sleep because it’s too hot. Which, unfortunately due to climate change, there are more and more of those nights in the summer.

I didn’t know it was possible to love an AC so much!! It is very sleek and looks sooo much better in my window than the old monstrosity of a unit I had before. Intuitive to use, especially the remote/app. My favorite part is that the air comes out of the top of the unit, so I can sit on my couch and not get blasted by air. Subtle yet powerful in every way.

we have storm windows and unfortunately had a terrible time with install! we looked everywhere for a full installation video, but found they skipped over dome of the useful parts. in the future, a full install video would be really helpful. now that it’s installed, it looks great and works great.

I was excited to receive my whisper quiet medium sized unit but there were some hiccups. The customer support team helped me deal with some shipping issues and after much communication, I now have my unit installed and it's great! really quiet. more quiet than the mini unit we installed last summer.

I LOVE my windmill ACs. I bought 3 for my 2 bed, 1 bath apartment and they work perfectly. They keep the space cool throughout a hot East Coast summer on the 5th floor. One of the ACs never made it despite saying it had been delivered. Customer service was one of the best I've ever had. They sent a new one within a couple days and made it a painless process. I highly recommend Windmill ACs for style, function, and great customer service.

We were searching for some new window ac units that were quiet, small enough to fit our new windows and attractive. While doing a lot of research, I saw windmill mentioned in several reviews online from reputable sources and so decided to look into them. I was having a lot of trouble finding nice looking 10K btu units that would fit our windows (in fact, I had to give away our only 2yo LG unit bc it didn’t fit the windows in our new apt) and was very pleasantly surprised that the 10j Windmill was small enough to fit! We decided to go with 2 smaller 6k btu units first in our smaller rooms to test out and were thrilled. They looked so much nicer than normal AC, we’re quiet and can be controlled on our phones. We then took the plunge with a 10k unit and couldn’t be happier with the results. It’s so quiet and our apt finally feels like it has central AC! Would 10/10 recommend.

I was looking for a clean, minimal style air conditioner that wouldn't take up a ton of room or make a lot of noise like my previous units. My new Windmill unit has been a dream. It's modern, stylish, and the noise level is low. I also love controlling it from the app when I'm out and coming home. Highly recommend!
