My husband and I purchased two Wind units last summer after our (not so old) units from a certain brand experiencing awful mold issues were deemed unfit for use. We are so distraught and really put time and effort into shopping for replacements. When we found Windmill, we knew we found a brand we could trust. Installing the units was a breeze - I did it 99% by myself, with a quick hand from my husband to support them before locking in. The custom side panels are amazing! Create a chic and clean look that feels very well insulated. The whole profile of the units is sleek and designer looking. Operation-wise, the units are whisper quiet and cool extremely efficiently/quickly. We will be moving homes this summer, and I'm honestly excited (something I never thought I'd say) to get our units in the new windows! Windmill is an changer when it comes to window ACs.

I purchased not just one but two Windmill air conditioners. After my first purchase of a 12K BTU WhisperTech for my living room, I followed with an additional purchase of a 10K BTU WhisperTech for my bedroom. They are super efficient and oh so quiet. Also they are so good looking too. So happy with my purchases. Highly recommended.

This window unit has been a lifesaver in an old house without AC. I love the automatic settings on the app so that I can turn it off or on remotely and save on energy costs when I'm not there. I like using the fan setting at times overnight for some white noise as well. It was easy to install by myself as well

I have 3 Windmill AC units, they're all quiet, efficient, and a breeze to install! Replaced older (not too old) traditional window ac units, these inverter units are significantly quieter, and cost effective. We can sleep at night with the unit going in our bedroom, and the smart app makes using them a breeze.Thanks Windmill!

I highly recommend the Windmill AC. We purchased the 12,000 BTU unit, and it keeps our large, open-concept kitchen and living area consistently comfortable throughout the summer. It runs very quietly, blends seamlessly into the room, and is easy to control remotely through the app.

I live in a small apartment in NYC — the Windmill AC was perfect for my shoebox-sized room. I loved the fact that I could control it remotely to cool down my room before I got off the subway, and I found it incredibly intuitive to use. I'm moving to a larger apartment in a couple months and looking forward to getting a second one. Also, my roommate's cat loves to sit by it too!

I have purchased 4 units for my home and an air purifier. All are aesthetically pleasing and efficient. They are quiet, sleek and keep our home comfortable! Being able to use the app before getting home has been key, as I don't need to waste electricity keeping them on all day. I have recommended to family members and friends.

The Windmill is the best window AC unit I've ever had. It looks great, is easy to maintain, has a good mobile app to control it remotely(not required, but useful), is easy to maintain, relatively quiet, and my favorite feature is that it blows cold air up, not out, so placing it in a window near a chair, seat, bed, etc. is much more comfortable than traditional window units. If you need a window AC, I'm not sure there is a better one on the market!

After having four other air conditioners, none of which did the job or they died after a few months, we discovered Windmill and what a gift THAT was! We're still amazed at how beautifully it works. The cooling is terrific, it's very quiet and we simply could not be happier! Plus, it looks wonderful!

This AC unit was so easy to install and was so quiet that I ended up buying a second one for my son's room. I bought the smallest one for his room and its so quiet and perfect for his small nursery. Also that fact that I can control the AC unit from my phone helps when the temperature changes drastically in his room and I don't have to sneek into his room while hes asleep. Wonderful unit!
