We purchased three Windmill AC units at the same time after unexpectedly needing to replace our previous brand, and we couldn't be happier. Affordability was important, but so was finding something that was both powerful and quiet—especially with Chicago summers that regularly hit well over 100°.We keep our window units installed year-round since radiator heat can be unpredictable, and even in the coldest months our home can feel uncomfortably warm. Because of that, we also wanted something that looked great and wasn't an eyesore. Windmill delivered on every front.I was initially drawn to the simple, clean design, but the performance has been just as impressive. We've used these units for three seasons now with zero complaints. Bonus points for the seamless Google Home integration—we love being able to adjust the temperature remotely and keep our dogs comfortable when we're away.

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.

We love Windmill so much, we retired our perfectly good Frigidaire air conditioner for our kids' room because we wanted something quieter, more intuitive and energy efficient after we bought our fist Windmill for our dining room several years ago and it cooled down the whole house. Saving for the next one!

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 love my windmill air conditioner. So quiet and efficient. The cooled air blows out from the top of the unit . The magnetic cover is a genius idea when cleaning the filter. Appealing to the eye and the side cover panels really add to the attractiveness of the unit . I'm planning on purchasing another in the future.

I purchased 2 WhisperTech ACs for my small NYC apartment after seeing how well the unit worked in my daughter's studio apartment. I am very happy with the units. They are quiet and I really like that they don't blow air out the front of the unit, but from the top! My bedroom unit is fairly close to my bed and I don't have the problem of feeling the cold air while I am sleeping. This is such a welcome change to the older unit I had that was loud and blowing constanting in my face! And in living room, there is no problem watching TV or listening to music because the AC makes only the slightest of sounds while on. Customoer service is also top notch. I was having an issue with the charcoal filters and my problem was quickly resolved. The employees are very responsive and helpful.

I love my Windmill AC. It looks so much nicer than most A/C's, it can be co trolled by my phone, and it cools quickly! The only down side is that it would vibrate at certain points when running, but thst was easily rectified by placing a wedge in the window (I used a piece of wood cut to size). It gave enough pressure on the window to stop the rattle.

I ordered the smallest Windmill AC for our 2nd floor hallway in our brick row house built circa 1850 in southwestern Ohio. Why on earth, you may be asking?- the summers are hot and muggy, with weeks well over 95 degrees and nights that just don't cool off.- our house is tall and narrow. 4 floors, including the stone basement, and everything is brick/stone so the heat hangs on in summer. In winter it's great, in summer you just want to lay on the floor in your swimsuit and drink Gatorade.- oddly enough, we have central A/C through out the 1st and 2nd floors and a mini-split system in the finished attic. It was an airflow issue. The ceilings are nearly 11 feet and with teenagers than kept their doors shut unless they were actively using their doors, the 2nd floor had zero circulation. Heat built up in the hallway where there wasn't an A/C vent and it was impossible to install one because the cool air from the ground floor forced it upwards. The attic mini-spits weren't designed to maintain CONSTANT, UNYIELDING action and were struggling to keep up with the warm air perpetually floating upstairs. The energy bill was ballooning wildly out of control and with my bedroom, bathroom, and work from home office in the finished attic, something had to be done.With one window 22 inches wide in the hallway, I ordered the 6k BTU unit and crossed my fingers. Installation took 3 minutes. The unit was directly across from my husband's office and he couldn't notice any background noise, even with the door open. Within the afternoon, the hallway was the same temperature as the rest of the house and the upstairs system shut off for the first time in weeks.That would have been enough for me, I was already celebrating. Over the rest of the summer, my energy bill was down roughly 40% despite having an additional AC unit. I've recommended it to several neighbors who suffered from the same issue and have a similar layout.

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!

I've owned a competitor u-shaped window unit and love the Windmill more! The design is perfect and doesn't stick out in our living room. It was incredibly easy to set up and I love that you can control it via your phone when you aren't home. I recommend this unit to everyone.
