We have had so much bad luck buying ac units in the past and despite storing them as directed in the winter, they always seemed to die on us. After hearing about Windmill and reading reviews we took a chance on this one, and it was worth every penny. It’s by far the most efficient, most quiet, and aesthetically pleasing ac unit we’ve ever had. It kept our home cool and comfortable throughout the spring and summer. And it was so easy to install and use.

We got this for our bedroom earlier this year because the one in our living room wasn't powerful enough to cool our room down the hall. This cooled our room so quickly, and it was much quieter than the one our apartment provided. I love that you can use the app to set it to turn on and off at specific times so we wouldn't need to worry about our cats being too warm during the day.

We have a Windmill AC we purchased this past summer. We live in an early 1800s farmhouse and needed something that could keep up with the heat and not drown out the space in compressor noise. The Windmill AC is exactly that. We put it in our dining room and no one knew it was running. It is so quiet and for being in our old style home with little insulation it runs efficiently and effectively. We're slowing understanding the environment of our old house and we may get another for our main bedroom. Right now we're using a few mobile AC units (along with the Windmill AC). The Windmill was a welcomed addition to our cooling needs.

We purchased two Windmill AC - 8K BTU WhispeTech air conditioners and love them! As a senior, the customer service team was helpful and kind in answering my questions about installation and care. The units not only look great but also are designed to be able to stay in my windows over my Vermont winter seasons eliminating the need to find others to help me remove and then reinstall the units each season.When my other older units need replacing, I intend to purchase more Windmill units!

We got an 8k BTU model which we already know is too powerful for the small 9 x 13 foot room it was put in. However, by leaving the door open the A'c does a marvelous job at cooling the room, the adjacent hallway and beyond. With simplicity of operation and it's quiet delivery of cool this A'C has my highest recommended. Now... if only they made a through the wall model!

I've now used this AC for my bedroom in two separate moves. Both places I lived in would get unbearably hot over summer, and the Windmill AC saved my life - it's my favorite thing I own! I especially love the timer feature, allowing me to fall asleep comfortably (I also love the sound of the AC to fall asleep to), while not having to have the AC run throughout the night. I also have a dog and could check on the app while I was at work to see if the room was getting too hot, then turn on the AC so my dog wouldn't overheat.My first bedroom was rather large and the AC was able to cool it down within minutes. My second room was smaller, and I never needed to run the AC on high because the lower settings are so powerful. I would use this AC no matter how it looked, but it doesn't hurt that it's pleasing to the eyes. Finally, it's super easy to install and uninstall. I've had it for 5 years now, installing and uninstalling it each season (it takes a matter of minutes with my boyfriend and me) and have taken it on two moves, and it's held up great!

You heard that right! This is the Rolls Royce of ACs! Why? Because it is quiet, cool-looking and just fits seamlessly into your life style or it might actually upgrade it! I’ve had several ACs in the past for a large room and this is the first one that actually cooled the whole room to my liking. Not too much or too little. Perfect just the way I like it! I bought their fan and their air cleaner because I’m so impressed with the AC. This is a quality product hands down! RUN, don’t walk, to order one for yourself. Trust me, it’s a keeper!

I love my Windmill AC. It was easy to install (though did take two people--its heavy) and continues to look gorgeous six months in. It has made my 100-year-old top-floor apartment livable in the summer, without sacrificing aesthetics. I love that I can turn it on from my phone when the heat picks up unexpectedly in the daytime, and know my cat won't be uncomfortable. I recommend one to everyone I know!

Our windmill AC was a life (and sanity) saver this summer! It kept our home cool and was remarkably quiet for a window ac. Also want to thank Mike and his team for their quick responses when there was an issue with the first unit we were sent. They made what would normally be a stressful process very easy. Very happy with this purchase!

So far so good. The air conditioner is quiet and appeared to be well made and efficient. Only time will tell.
