One Star

Would Not Recommend

⭐ 1 Star — Very Disappointed With These Air ConditionersI purchased three of these air conditioners approximately one year ago, and unfortunately, they have been giving me problems ever since.One of the biggest issues is that when it rains, water gets in through the bottom of the units and leaks heavily. They also do not cool the rooms sufficiently, which is especially frustrating during hot weather.I regret getting rid of my old air conditioners. They were a little outdated in appearance, but t...

WOW!!!!

Would Recommend

We formerly had a 10,000BTU window A/C unit that had to weigh close to 100lbs. The Windmill 6KBTU was half that weight, easy to install and the app is really cool to control it away from home. And best of all, it cools the living room twice as well as its predecessor.

Didn’t even last 2.5 years

Would Not Recommend

Very overpriced for not being able to last 2.5 years. The WiFi app would constantly go in and out, which ok fine - we can deal with that. But breaking down and forming ice on the coils repeatedly despite following all instructions, very expensive item is now in the trash. After 2.5 years, ice would form within 15 minutes of turning on the AC, I’ve had window units last 15 years, guess they just don’t make them like they used to.

Cord is too short

Would Not Recommend

I haven’t been able to try mine yet because once we installed it we realized the cord was just a bit too short to reach the outlet. Seems ridiculously short to me, especially since the instructions say not to use an extension cord or surge protector.

WiFi cannot be turned off

Would Not Recommend

I didn’t realize the WiFi could not be turned off. We do not use the app. Constant on could be a security issue. Also signed up with special for extra filters, haven’t received them. Said shipped on my email. Not a fan of a subscription service on that either. Air only comes out of top of vent, in one direction, up. Install was easier. Looks nice. Quiet compared to our old unit.

Amazing AC with outstanding customer service

Would Recommend

We bought 2 ***** BTU ac units and they are a game changer compared to the regular window units we had before. Besides the obvious esthetic of them looking sleek and modern, its amazing how quiet they run. The built in smart feature is very convenient and the fact that the vent doesn't blow straight out is really awesome. We had an issue with one of the units and emailed the company. Customer service was quick and efficient and we got a replacement super fast and everything works as it should. W...

Stopped working properly after less than a year

Would Not Recommend

I barely used it in my room. Only for couple hours during gaming. Before bed. Usually I play video games in my home office between 10 pm and midnight. So during that time I turn on this ac. After 11 month of using it stopped working. I mean fam is working but no cold air coming out of it. I regret that I purchase this model for almost $700 I could have and should by some cheaper model for like $150 it would do the same thing or even better.

GREAT AC - GREAT CUSTOMER SERVICE

Would Recommend

I had an issue with the plug not working on my Whisper Tech unit and not only was customer service very quick to respond but they were also very quick to resolve the issue with a new unit. I received the replacement fast and it's working great! Very quietly, too!

Would Recommend

After being thoroughly satisfied with the style and function of our first 8K BTU unit, we just installed a new 8K unit in our second bedroom. These ACs are amazingly quiet, efficient and user-friendly. And I love the WiFi connectivity feature through the factory-supplied phone app.One caveat: I had some difficulty connecting both units to WiFi. I forgot how I fixed the issue first time around, so when I reached out to the company for assistance, one of the co-founders replied right away and remi...

Quiet, Clean, and Efficient

Would Recommend

I got two Windmill AC window units with Whisper Tech. They have been amazing with cooling the entire apartment. I love how easy it is to change and automate the temperature and modes using the mobile app. The units are also quiet with only the occasional sound of turning on. I also got the filter, which has made the air quality noticeably cleaner. Overall, a wonderful purchase!

Ups delivery

Would Recommend

Product is great. Up air direction causes overhead fan to rotate which is better for getting over nearby furniture. Very quiet. Easy to install.Ups refuses to read special instructions needed because of construction. Windmill stepped in participing in solving the problem.

Incredible support

Would Recommend

My Windmill 12,000 BTU AC ran into some technical issues. When I got in touch with Van in customer support, I was hoping to get some assistance, but was very pleasantly surprised with the level of support I received. He resolved my issue immediately and genuinely jumped through hoops to make it happen. Very grateful.

Perfect A/C for my 400sqft Studio. It's powerful and looks great. I generally like the design and control options.
