I have to say that I do not write many reviews, but I do have to give credit this company for an excellent product they produce. The AC was one of easiest to install. Also, the size was perfect for our room and works whether through WiFi or manual. The ac blows cold and maintains room temp extremely well.

We weighed investing in a ductless system vs the windmill and ultimately decided for our needs, the windmill ac unit was perfect. We purchased the 8k btu with the whisper tech feature since this is for our second floor and is placed in our master bedroom. Our central AC just does not really work for the second floor. This unit Iexceeds our expectations. It was super easy to install, it’s very quiet and efficiently cools not just our second floor but, as a bonus, also our first floor. We have our central air set at 80 degrees and the downstairs temp reads anywhere from 70-75, depending on time of day and outside temp. The upstairs is super comfortable and while we have the windmill unit set at 75 (on eco), it consistently reads lower. To be fair, we have a brick house and great insulation. My husband says this is the sleekest window unit he’s ever seen and he’s right! It looks good on both sides. We definitely do not regret our decision to just get the windmill vs the ductless system.

Overall pretty great, it cools really well and since it's right behind our bed I'm happy it's not blowing right on top of our heads. The eco mode is nice, but the going on and off during the night does wake me up a bit. That said, after endlessly searching for a reasonably eco friendly option for an AC, I'm very happy with this one.

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

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.

I love my new AC! I got the 12,000 BTU one because I have about 1,500 sq ft down stairs. It cools the whole place very easily! I love having the app on my phone to allow me to turn it on when I'm on my way home. I just purchased another one for my upstairs area! Super easy to install in the window and it's nice to have the winter cover so I don't have to remove it from the window. Just need the 12,000 BTU cover to come back in stock to get one!

I purchased a 10,000 btu air conditioner for my living room and love that it was easy to install, its quietness when on and simplicity in operation. A plus is that I can turn it on from my iPhone. I liked it so much that I bought a 6,000 btu Windmill for my bedroom. I hope they make a through the wall model soon.

My wife and I bought a 2nd Windmill, this time the newer (and smaller), 6,000 BTU model. Considering how well it works, how much nicer it looks in the room than our old (non Windmill) unit, and the ease of set-up, I'll never buy another company's AC unit again. Our reason for not getting a second (or third) unit was the size of the space/smaller window in a particular area, and now Windmill has solved that problem too by offering multiple outputs. In fact, we're looking into a third unit for a similar reason right now. No matter which you buy/your AC needs, we can't recommend Windmills enough!

I chose the Windmill 12k BTU over a cheaper, different brand 12k because of the direction of the airflow, and it's awesome and so worth it. It cools the room effectively without it being a jetstream of cold air in one direction (my window is nearly behind my couch, so past ACs have directed the blast at the back of my head). The first unit arrived and had a strange rattle in it, but we installed it anyway. Within a day it froze over with an inch of ice all over the insides. Contacted customer service and they responded super fast-- walked us through a few questions and quickly determined it was likely a damaged unit. Warrantee claim initiated, and a new unit arrived within a week. Honestly I couldn't believe how excellent the customer service was. If I need another unit for another room in my house, I'm going with Windmill because I know if any issues arise they will be taken care of promptly and efficiently. My only gripe is I wish there was a little more control within the app-- if set to "cool" the unit seems to keep cooling even as the room temp drops below the set value. It would be nice if it powered off and back on later, but maybe it switches to fan only and that's enough? It could be nice to link it with a different thermostat reading too, as it's interpretation of what temp the room is at seems a bit off when on eco or sitting idle. I imagine these things might get dialed in with some software updates. I'm also a big fan of actual buttons on the unit. If I can't find my phone I can still turn it on and choose settings and temps without any difficulty. All in all, love you guys. Great product, great company. Keep it up!

I am so impressed with this air conditioner! My son needed something small and easy to install in his bedroom window and something attractive looking! It was not only easy to install, it is easy to use and quiet,,,,huge plus! His room is now nice and cool!
