I needed to replace a 15-year-old 5000 BTU A/C this summer since it wasn't cooling as effectively (and my town offered a rebate for recycling inefficient appliances). I'd seen ads and reviews of the Windmill, so I convinced my wife to let me order it. The install was very easy. The most difficult part was taking out the old unit. Controlling the unit via the app is easy, and I like the energy use meter. We also go out of town once a year, so the ability to start it the day before we return is very helpful (much better than returning to a 90°+ house). I also ordered one of the interior covers, and it's doing a great job of keeping the cold weather from getting in during this winter storm.

We needed a better AC to cool our first floor area and our old one was so loud and inefficient. I saw an ad for Windchill and figured we give it a try. Needless to say I want to purchase more to put in other areas of my house. Really glad I got one! Highly recommend.

We got this for our NYC apartment and love it. It came with everything we needed to set it up, and it looks as chic as an ac can in the window. It's also well-insulated enough to stay up year-round, and of course it keeps the apartment nice and cool in the summer.

I purchased this window air conditioner because my husband and I like to keep our bedroom cold at night for sleeping but I didn't want to waste energy cooling down and heating up our whole house. This was the perfect solution – easy to install without any special equipment and way quieter than any other window air conditioner I've ever used. We went with one just a little more powerful than we needed for our space because we wanted the quieter motor and I'm happy with our choice. I also like that it will be easy to take with us to another house if we move again since it is not a permanent installation.

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.

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.

As a Coloradan, migrating to New York City five years ago was... sticky. Pretty sure I'd never experienced heat, humidity—ALL of it like it was in NYC. And to top it off, he's a hot sleeper!! I tried serval units over several years until I finally found the one... Windmill! I'd still have it many years later if I hadn't moved into a building w central air. THANK YOU WINDMILL

I live in 100 year old building with 4 exposures (n,s,e,w). We have to rely on AC units to keep our apt cool. We bought 3 units and it has seriously helped. The units are understated, not obnoxiously loud and best of all the app woes quite well to turn the units on before we get home. It's so easy to program them to turn on and off that it almost feels like central air because when we come home it's actually cool! I had an issue with one unit and the customer service was also great. Stand out product and buying experience.

I have a small house in upstate New York that is about 1000 ft.2 and my 10,000 BTU Windmill Air extremely quietly cools the whole house even in the hottest days of the summer. It's attractive, easy to change filters on, and extremely quiet, which is what I really need since I sit very close to it in my living room. It is certainly the best air conditioner I've ever had and I have suggested it to many people. It is well worth the money spent. I have now gone through two summers with my Windmill Air and I can report that it runs like a charm.J Lotus

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.
