Awesome little window AC

Would Recommend

I got the 6000 BTU version for a teenager’s small bedroom. The unit was great. Very easy to install. Looks sleek. Having it available through the app is a nice bonus. Plan to replace older, less efficient units with other Windmill ACs this coming summer

Amazing!

Would Recommend

Excellent product and outstanding customer service! The AC does a fantastic job keeping the room cool. What truly impressed me, though, was how responsive, and helpful the support team was after I contacted them about an issue I had. They were kind, attentive, professional, and truly committed to helping/making things right. It’s refreshing to see a company that truly cares about its customers, and stands behind its products. I’m beyond satisfied, and would highly recommend them to anyone lookin...

The Upgrade of a Lifetime

Would Recommend

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 ...

World of Difference

Would Recommend

Even though I had a new HVAC system installed, I was still uncomfortable upstairs, in my 1925 home. None of my friends had heard of Windmill before, but after I read a review on Wirecutter I decided to try one for my bedroom. It arrived quickly and it was light enough that I could carry it upstairs myself, with little effort (69 y.o. female). In less than 30 minutes, with a little assistance from my teenage granddaughter, we had it installed; it quickly & quietly cooled my upstairs, beyond the b...

Perfect for my Sunroom

Would Recommend

Summers in Texas Hill Country can be brutal, especially in a windowed room with no central air. This gem has made my Sunroom a cool utopia for my pack of rescue dogs. Everything about the unit was a breeze (pun intended). The order arrived quickly. It unboxed easily, and setup was detailed step-by-step in the instructions. As a 64 y.o. woman, I was able to do the install all by myself. And with the app, I can control its functions from my phone. I am so impressed, I also bought a Windmill Air Pu...

Quiet but powerful!

Would Recommend

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!

love my upgraded AC!

Would Recommend

I've been using windmill ACs for several years now, and a major plus is that I can control the unit via the phone app even when I'm not home. Not only does it work well, the design of the AC looks beautiful in my apartment. I used the original model (6k BTU) for 3 years, but after moving last year I decided to get the new WhisperTech model (8k BTU) and am super impressed with how much quietier it is and how quickly it cools my home. The customer support has always been fantastic as well!

Love our ac!

Would 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.

Cool in NYC

Would Recommend

Had a few AC's over time and when it was time to replace I tried checking out the Windmill site.Picked out one that looked good and small for a NYC apartment with and was fair priced.When we got it, getting it into the window was super easy, and it looked great but let’s turn it on....When this was going on NYC was in the middle of a heatwave, so we got it just in time, and once we turned it on we wore pleasantly surprised at how quiet it was and even better, during a heatwave how fast we wore c...

Great A/C

Would Recommend

This A/C has been a great investment. It cools very well, runs quiet, although I like the white noise for sleep. I haven’t had any issues with it staying connected to WiFi and the app works great. I set up an automation for it to come on at a certain time of the evening and it works flawlessly. Overall great product!

Fantastic Product

Would Recommend

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

Happy to have purchased

Would Recommend

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.

Double Happy

Would Recommend

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.

8k btu

Would Recommend

Looking for a new a/c and didn't like the look of any them until I found Windmill. Bought the 8k btu and am very pleased with the quietness of it. Keeps my living room nice and cool. I would recommend this company to anyone.

Great product

Would Recommend

The design is simplistic so it doesn’t stand out like a sore thumb in my bedrooms and living room. - The low humming as opposed to louder clanky sounds of the other typical brands is the selling point for me! I also like that I’m able to program it from my phone so on those hot days I can have the house cooled down before getting home. - customer service was also very accommodating and punctual. Overall I’m very happy with my purchase.
