Windmill Window Air Conditioner - Quiet & Smart, Easy Install, Voice-Enabled, Remote & App Control AC Unit - 6,000 BTU

I have a very limited space on a 3rd floor apartment in an ancient house - so summers get hot. Unfortunately, there's really only one space for my dog's bed to go, and for the past few summers she's had to compete with the AC hanging loudly over her bed. Not so with the Windmill. It sits much shallower in the window, though the extra screw points leave it more secure than my past unit. It's sleek (which I like) and quiet (which she likes) and voila - I don't have a hot dog in my bed, she doesn't have a loud AC in hers, and everyone in the house is much happier. Even before the app, it's a superior option to standard units (and for folks who are app averse, you honestly don't even need it). Once you factor in the technology and sleek design, it fits in really nicely to the space (and yes, it does the job too - nice and cool). Life saver for me!

From the moment I unboxed the Windmill AC, I knew I was in for a treat. The sleek unit blended into my living space as if tailor-made for it. Setting it up was a breeze—I had it purring quietly in the corner of my room without a hitch. It's the little things that make a difference; the gentle hum that fades into the background, allowing me to focus on my work or drift off into a peaceful sleep. And with the intuitive app, it feels like I have the weather at my fingertips, adjusting the climate of my room from the cozy confines of my couch or even when I'm away. But it's not just about comfort—the Windmill AC speaks to my environmental conscience. Knowing that my choice helps in reducing my ecological footprint adds a layer of satisfaction beyond the immediate cooling relief. Every time I power it on, there's a reassuring thought that this small luxury aligns with my larger values. The Windmill AC isn't just an appliance; it's a part of my home experience, seamlessly integrating convenience, care for the planet, and personal comfort.

Finally, Windmill has provided me an A/C unit that feels like it was made for this century. For too long we've dealt with old units that are too loud, too manual and straight up ineffective. The windmill solves all three problems! First, this is by far the quietest Air conditioner I've ever had! Gone are the days I need to watch TV with subtitles because I can't hear over the thunder that is my A/C unit. Not sure what whispertech actually is, but it delivers on the promise. Next, it's great to have a window unit A/C system I can control through my phone. I can easily change the temperature in my kid's room without going in and waking them up. The app is easy to use and just requires a few clicks! Finally the windmill is effective. Without cranking up our energy bill, we are constantly cool even in hot summer months. Definitely will continue to buy the windmill for future A/C needs!

Cool stuff (pun intended) doesn't have to cost a fortune and can also be a great product. Windmill's AC is one such example: Subtle, modern design; great (quiet) performance; thoughtful, intuitive, installation provisions and instructions. Kudos to the young hipsters in Brooklyn from an older - yet much cooler (pun doubly intended) - guy in Manhattan.

I purchased this unit in 2023 and loved it. It cools my bedroom well and I enjoyed using the app, it looks great and is easy to install. Fast forward 2 years later I start experiencing technical bugs - disconnected from the app, random beeping, modes/temperatures changing on their own. I contacted Windmill support and they recommended a hard reset. After conducting this reset, I haven't been able to get the unit to cool for even 30 seconds before it starts malfunctioning. Windmill support said that the unit's control board malfunctioned, but since I am 1 year past the warranty, they would not provide me with a replacement despite this being a product defect. Don't waste your money. Having to now replace a $350 machine after just 2 years is a huge letdown, and I will be buying a cheap little frigidaire that will likely last 5+ years at a fraction of the price.

All windows AC, regardless of brand, perform one function; cool down a space/room. For this review, I am putting installation and operations aside. I am only focusing on the most important aspect to me, the noise level. Based upon the many positive reviews, I purchased a Windmill Air Conditioner Smart Home AC Unit 6000 BTU for a small home office (12ft x10ft). The test setup: Sound measuring device = Samsung Galaxy S6 & Sound Meter app by Abc Apps. Table setup at 8ft directly in front and at the same height as AC. Thermometer = DIGI-SENSE Traceable Wall-Mount Digital Clock/Calendar x2 I began the test by making the room as quest as possible. Everything was shutdown, windows and doors closed and all outside noise within my control were also turned OFF. I measured the room noise level, then set the AC unit to Cool, Fan Low, Fan Medium and Fan High. Results are: OFF (room dB) = 21 Fan Low dB = 49 Fan Med dB = 51 Fan Hi dB = 53 I was surprised and somewhat disappointed to say the least. This was loud. From all the reviews, I thought the noise level should be lower. Windmill Air advertised this to be quiet. It’s louder than my 15 yr. old Whirlpool. Definitely very loud for sleeping. It’s in the office, but I will have to shut it down for virtual meetings or calls. Another note: The temperature gauge is consistently off by about 8-10 degrees. Its reading 63 degrees while the room thermometer is reading 73. This is occurring all the time. The unit shuts down while the room is still warm. My room thermometers are Digi Sense 08610-26 Traceable Wall-Mount Digital Clock/Calendar NIST which are calibrated and compliant for ISO, FDA, and cGMP manufacturing environments. I’m fairly confident that the Windmill Air AC’s temperature control is in-accurate. I have two different brand AC units in the bedrooms which I will put into the same test. More to come…. UPDATE: I have to give a shout out to Windmill Air's customer service. They were very supportive and we went over several debug methods. 5 stars to customer service. The rattling noise was still there after debugging and in the end, they sent me a replacement unit. I put it through the same test as described above. While the rattling noise was gone with the new AC, the noise level itself was not as quiet as expected. The decibels were still the same. I did a comparison with my other two ACs: Midea 8000 BTU U-Shaped and a 15 yr Whirlpool ~1800 BTU. The results are: OFF (room dB) Fan Low dB Fan Med dB Fan Hi dB Windmill Air 6000 BTU 21 49 51 53 Midea 8000 BTU U-Shaped 21 32 35 41 Whirlpool 21 42 49 49 The Midea was truly quiet coming in at 32dBs on low fan setting. Perfect for a bedroom. The Windmill Air is ideally a small office AC and the noise level is acceptable for that purpose. I have upgraded my review to 3 stars for the level of customer service.

The appearance is quite nice. The air outlet faces upward. In terms of noise levels, it performs remarkably well—it is very quiet. I can't even spot a drainage hole; it seems there is no drainage mechanism. Furthermore, the product description makes no mention of a drainage system.

My reason for only 2 stars (despite this being a great AC) is that it causes internet connectivity issues for your other devices like phones and laptops. This AC continuously runs its own 2gz wifi network called WindmillAC-2E076 that cannot be turned off. It crowds your wifi in the area and if you are near others in the same band, it will affect your internet connectivity speeds significantly. If you pair it with your own Wifi Network, it may kick off another device that you were using. Unless you have dual band routers capable of running a separate network just for this AC. With that said, this quickly became an annoyance rather than a convenience. This needs a feature to turn off Wifi or the Wifi network. Now for the AC functionality itself: Highly efficient and Draws a lot less wattage than other window AC units. Perfect for running in Solar Installations. Cools OK and is relativity quieter. Very Easy installation. I installed it by myself on my 3rd floor window within 10 minutes.
