Windmill Window Air Conditioner - Quiet & Smart. Easy Install, Voice-Enabled, Remote & App Control AC Unit - 12,000 BTU Inverter w/WhisperTech

1st bought the 8,000 BTU whisper tech for our bedroom last summer and we love this a/c so much that hubby and I got the 10,000 BTU whisper tech version for our living room! In comparison to the older a/c units we had in our apartment (3 a/c’s were graciously left behind when we bought our apartment), windmill whisper tech is very soft and quiet—even on the highest fan settings and on cool mode. I love being able to turn on both a/c’s remotely through their app a few hours before coming home and to enter into a significantly cooler apartment after a hot NYC summer day. I also truly enjoy the sleek design and the 45* upward fan that helps to make the room feel cooler faster rather than a standard a/c blasting just one area and that area being very cold. Installation is very intuitive and easy with all the tools you need to make it a breeze (including a nice pair of scissors for the sleek side panels)! Especially after setting up our first one, it takes about 20-30 minutes to set up and use right away—if you need to install a/c brackets, add some more time. If you able to splurge the extra money for the whisper tech a/c’s—especially if people are sleeping where this a/c will be—it is very worth it! I have observed that the set temperature may be slightly off from the actual output or readings in the room (ex: a/c temps are set to 68*, it says that the room temp is 74* but external temp reader reads the room at 76*). This is not a huge deal breaker for me as long as the apartment feels and is under 80* but it may be something to keep an eye on over time. Overall a very solid unit and looks sleek and works very well for me and my hubby’s needs. He is a light sleeper compared to me and is sound asleep while running this a/c!

The two 8000 but units that we purchased have worked well this last season. They are reasonably quiet compared to the window ac units we've had over the years. What I really like is that the cool air comes out the top instead of in your face. It circulates the air better and no shutters to clean or break. They are as easy to install as any standard window unit, and the side panels make for a neat installed look. The app is good, though both units had instances where the room temp display froze up on the app and wouldn't update until the units were unplugged, then plugged back in. Otherwise the app is pretty informative. The remote works fine, but as it's an infrared unit the range is limited. The magnetically held filter cover is pretty trick, and the filter is the same type as you'd find in a split system, plus the charcoal filter. After running them this summer I'm impressed. They're not perfect, but nothing ever is in this world. If the app was flawless, and with an rf remote it would have earned 5 stars. Update: Both 8000 btu units are in their third season and running fine. The app works well enough that I don't know where the remotes are, and I can adjust them anywhere my Wifi signal reaches. With one unit on each floor of our tree shaded 1400 sq. ft. Cape they keeps things nice and cool in temps up to the upper 90's. They look good, work well, and have held up just fine. I took a chance with a relatively new manufacturer and it paid off. I'd buy them again. Update: I ordered a new 5000 btu unit for one bedroom that was tucked away and so far it's worked well. The room is about 150 sq. ft, in size, and it cools the room down very quickly. The assembly instructions were clear and easy to understand. The top rail goes on with a few screws, then the thick accordion panels slide into the sides, and the frames are pushed into the rails. Thats it. It has the same minimalist look but it's a little different from the larger units. The cool air exits from the top front which swivels from straight out to upward, and a small lever to adjust it from side to side. The display is nice and bright and goes blank after a time delay. I did have an issue with the filter. It was hard to insert into the side of the unit, so I reached out to product support. They responded quickly and sent instructions to make it easier to install. It's only been installed for a couple of weeks and so far I'm pretty happy with it. It linked to the app right away, it's nice and quiet and cools the room in a jiffy. 5000 btu ac unit Update: I contacted Windmill about the filter installation issue and they responded that night. They shipped me a new filter after a couple of weeks that's designed to be easier to install, and it works! Now it slides right in with no issues. Our cooling season has pretty much ended up north so the units will be stored for next season. The 8k btu units are still working flawlessly, and the 5k btu unit is working fine with the filter upgrade.

I've been a satisfied owner of two Windmill AC units – an 8000 BTU and a 6000 BTU – and my experience with these products and the company's customer service has been nothing short of outstanding. Product Performance: I purchased my first Windmill AC unit (8000 BTU) on April 26, 2022, and it has been an essential part of my home's climate control system. This unit not only cools efficiently but also operates quietly, which is perfect for a peaceful home environment. The second unit (6000 BTU) I bought on May 23, 2023, works flawlessly in another room, providing consistent cooling without any issues. Advanced Integration: I have an advanced setup in my apartment using Alexa automation to monitor various sensors. These sensors track indoor temperatures, weather forecasts, and my location to optimize the AC settings. This ensures my home is at the perfect temperature when I arrive from work. The setup was seamless, and the Windmill AC units perform flawlessly within this system. It's been a lot of fun dialing it in, and the units are incredibly reliable. Customer Service: Recently, I encountered an unusual issue with my 8000 BTU unit. Despite being out of the standard one-year warranty, the customer service team at Windmill, particularly Lois, went above and beyond to assist me. They suggested various troubleshooting steps and were very patient as we worked through the issue. I will mention that appliances these days use computer boards and I have an extended warranty on my other unit and do recommend others consider the benefits. When the problem persisted, they offered to replace my unit as a gesture of goodwill. This level of customer care is rare and highly appreciated. The replacement process was incredibly smooth, and the new unit was shipped promptly. Their communication throughout the process was exceptional, making the entire experience stress-free. Final Thoughts: Windmill has earned my loyalty through their high-quality products and exceptional customer support. If you’re looking for an efficient, quiet, and smart-compatible AC unit, Windmill is the way to go. The seamless setup and outstanding customer service make it a worthwhile investment. Recommendation: I wholeheartedly recommend Windmill AC units to anyone looking for a reliable and efficient cooling solution. Their product quality and support team are second to none. I'll be sharing my positive experience on every review platform possible because they truly deserve it. Thank you, Windmill, for not only providing great products but also for standing behind them with such amazing customer service.

The product is modern, very quiet and looks great YET about 4-5 weeks into its "life" it has TWICE unexpectedly made a LOUD clunk, shut down and restarted. I am not an expert on AC units but I would guess this a sign of a defect in either the compressor or invertor. To be clear, this is twice in perhaps a 8-16 hour span of its operation. After providing Windmill with all of the necessary documentation and description of the problem, Windmill has notified me they are a small company and they can NOT honor their warranty unless I can provide VIDEO documentation of the problem. This would make sense if a unit began squealing, spewing out smoke, making continuous loud rattling sounds but WHO is going to sit next to an AC for hours or tens of hours waiting to capture an obvious mechanical flaw on video? Now the weather here in the Northeast has turned to Autumn, the only option I have is to take the unit out of the window, store it for the winter and reinstall it in the Spring ... hoping the defect eventually becomes predictable and commonplace enough to video it. To be clear, Windmill is NOT doubting nor disputing my claim but rather standing behind their policy that they cannot and will not provide warranty service without VIDEO evidence. Therefore my recommendation is to buy one of their 10,000 BTU units if and only if you want a quiet and efficient AC which may or may not develop a mechanical defect within a few weeks ... which Windmill will refuse to service under warranty. I own TWO of their units, have experienced a problem with one of them (in less than two months of intermittent use) and simply don't have the funds to play Russian Roulette with my next AC purchase. Perhaps something positive can be said about the huge appliance manufacturers who WILL stand behind their product. Something to think about: Would you buy a new car from a manufacturer who - when you report the car unexpectedly "loses its steering" every 400 miles or so told you they would honor their warranty if and only if you provided video evidence of this occurring??? If you think this example is extreme ... are you confident my Windmill AC will not create an electrical fire which burns my house? MY suggestion: If you are buying a Windmill AC unit, first compare the model number and serial number to see if either closely resembles mine and think twice about whether you want to spend your money for a product with a VERY seller-biased warranty

I’ve had to deal with Window units on and off over the last 40 years, some pretty new and some built in the early Sixties (they are REALLY heavy), but I will say this is the nicest I’ve used. But expectations are everything, if you think it will be a miracle machine you may be disappointed. But if you like good industrial design, care how it looks, and love the idea of controlling with your phone, I think you’ll be pretty happy with it. It was easy to unpack, easy to install (with really clear instructions), didn’t require anything not in the box to install (yes, it really does come with scissors to cut the side panels. If you think that’s ridiculous you haven’t been around people under 30 much lately), it’s powerful, and has a great App. I don’t want to pick on anyone else’s review, everyone has their own pain points and expectations, and yours may not be met: no product can be perfect for everyone. But I think it’s a good, well made, and quiet unit, that looks nice and does pretty much what they say it will. The “Inverter” that comes with the WhisperTech just means that the compressor is variable speed; unlike the old units we dealt with that only ran at full blast, this guy will speed up and slow down depending on how much cooling is needed. This can cause the unit to rattle on startup, or make noises when it’s changing speed that people aren’t used to associating with AC units and they assume it’s a flaw. It’s really just a temporary side-effect of a great feature: variable speed means it’s quieter and uses less energy just keeping your room cold than it uses to get it cold in the first place. This is a good thing. I don’t leave a lot of reviews, and this product doesn’t really need any help, it has a great star rating already. But I do see a fair number of one star, “Just don’t buy it!” reviews that are based on things like it broke after a week or the filter isn’t a HEPA filter and that makes the whole thing useless, where they are not reviewing the unit itself, but rather their disappointment that it failed in one specific thing that they hate (it doesn’t say it has a HEPA filter—you may want one but that’s not a flaw in the unit). Just read the description they gave it, and strip out all the shiny phrases and exclamation points marketing put in, and decide if the product they describe is what you want. As I said way at the top, before we all got old reading this review: it’s as good as they say it is. I think most people will enjoy it and think it was worth the money. Enjoy the rest of the reviews!

This Windmill A/C unit fit perfectly in the window of a trailer that I rent out to tenants. I gave it 4 stars due to the left accordion panel being disconnected from the outside of the frame, cutting my fingers up trying connect it myself and then going through the email process with customer service. It was a daunting task trying to get the precise information to them. I was sceptical that I'd get what I needed, but they came through and gave me both the right and left panel replacements when I only needed the left. They were both firmly attached and I was very pleased in the end. The price point was reasonable compared to other air conditioners that I reviewed and it does a great job cooling the room without being too noisy. It's easy to use and function well. It also comes with a remote and an app that allows you to turn on the unit well before you arrive home. I would highly recommend this unit to others despite the slight manufacturing assembly error.

⭐⭐⭐⭐⭐ Perfect for my small space, and it looks modern too. I’ve been using the Windmill 5K BTU in my studio apartment for about a week now and it’s honestly been such a great addition. I was worried it might not be powerful enough since it’s a smaller unit, but it cools my room super quickly. The setup was really easy, everything you need comes in the box, and I had it up and running by myself in under an hour. I also love how it looks. Most window ACs are bulky and kind of ugly, but this one actually blends in with my space and doesn’t stick out like an eyesore. One of my favorite features is the app. I like being able to adjust the temperature while I’m out, so I can come home to a nice, cool room. The lights on the unit also auto-dim at night, which is a nice touch when I’m trying to sleep. If you’re looking for a small, quiet, and modern-looking AC that actually works really well, I’d totally recommend this one.

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.
