Great and quiet a/c unit!!
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!

Updated third season review/ new 5000 btu unit addition
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.

⭐⭐⭐⭐⭐ Exceptional Product and STELLAR Customer Service
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.
