There have been none that live up to that name except for this one. It installs in minutes, like 5 minutes! So easy a caveman could do it. It looks great in the window ( see attached photo) . and once you turn it on and let it run for 5 or 10 minutes it quiets down o the point where you barely recognize it's on. I use it to cool my entire 2 bedroom apartment and love that when it is on I cannot hear it all in my bedroom which I leave the door open and use a tower fan to bring the cold air to me. At first you will hear not the typical loud humming of an average AC which never gets any loqwer, but a sort of buzzing sound. Thhis will be noticeable for about 5 or 10 minutes as the AC begins to cool the room. After this time that sound will go almost inaudible and all you will hear and very low wooshng of thefan if set at low. In fact if set at low you might not even hear the fan at all. The buzzing gets barely audible if you are in the same room and unnoticeable in other rooms. And unlike other ACS when it cycles on and off there is no noticeable big shaking of the window pane or in the walls. It just goes on, the buzzing starts and then goes away. The longer it stays on the quieter it gets. So as far as the AC is concerned , it's great. Cools 900 square in 30 minutes at high fan which i then turn down to low. Is very very quiet, and looks super clean in the window. I'd say buy this one. My only negative about this AC is the Wifi App to turn it on and off remotely. When I first installed it, it worked fine. I was able to turn the AC on or regulate the temperature when i was at work to get ready for my arrival and turn it down or off when i was out. Very handy indeed! I loved it. However it stopped working, and when i tried to re-install and reconnect , well lets just say after 5 or 6 attempts ( and I'm very tech savvy) i got frustrated and deleted it all my data. Kudos on the AC but fix the APP to make this a super special Air Conditioer Review: 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. ## Features - SMART, EFFICIENT COOLING: Unlike standard window a/c models, Windmill’s WhisperTech dual air intake design pulls in air from the front and the bottom, improving efficiency and delivering ultra-quiet, room-wide cooling at a perfect 45° angle. - ENERGY-SAVING PERFORMANCE: With double-insulating side panels, this window air conditioner keeps cool air in, blocks outside noise, and reduces energy consumption for lower utility bills. - CONTROL FROM ANYWHERE: Control your AC from anywhere using the top-rated Windmill Air mobile app, plus voice control compatibility with smart home devices for ultimate convenience. - PREMIUM FEATURES & DESIGN: This air conditioner includes dual-filtration with a washable mesh filter and optional activated carbon filter, auto-dimming LED lights, 3 cooling settings, and 3 fan speeds for customized comfort. - QUICK & EASY INSTALLATION: No tools, no hassle—this window ac unit comes with a pre-assembled install kit, so you can set it up quickly and enjoy powerful cooling without complicated instructions or heavy lifting. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C4WFLF75 | | Additional Features | Remote Controlled | | Air Conditioner Application | Residential Indoor | | Best Sellers Rank | #105,217 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #16 in Window Air Conditioners | | Brand | Windmill | | Brand Name | Windmill | | Capacity | 0.67 tons | | Color | White | | Compressor Type | Inverter | | Control Method | Remote, Touch | | Controller Type | App Control, Voice Control, Remote Control, Button Control | | Cooling Power | 8000 british thermal units | | Customer Reviews | 3.9 out of 5 stars 1,725 Reviews | | Efficiency | High | | Filter Type | Standard filter | | Floor Area | 350 square_feet | | Form Factor | Window | | Installation Type | Window | | Inverter Type | Has Inverter | | Item Dimensions D x W x H | 22.5"D x 19.3"W x 13.3"H | | Item Weight | 61 pounds | | Manufacturer | Windmill | | Model Name | 8000 BTU WhisperTech | | Model Number | 08W2Wi | | Noise | 40 db | | Number of Power Levels | 1 | | Operating Mode | Cooling | | Outdoor Unit Compatibility | Requires New Outdoor Unit | | Power Source | Corded Electric | | Product Dimensions | 22.5"D x 19.3"W x 13.3"H | | Refrigerant | R-32 | | Room Type | Bedroom | | Seasonal Energy Efficiency Ratio (SEER) | 14 | | Special Feature | Remote Controlled | | UPC | 860003069523 | | Unit Count | 1 Count | | Warranty Type | Limited | | Wattage | 690 watts | | Window Opening Maximum Height | 36 inches | | Window Opening Maximum Width | 24 inches | | Window Opening Minimum Height | 13 inches | | Window Opening Minimum Width | 36 inches | ## Product Details - **Brand:** Windmill - **Capacity:** 0.67 tons - **Color:** White - **Cooling Power:** 8000 british thermal units - **Filter Type:** Standard filter - **Noise Level:** 40 db - **Product Dimensions:** 22.5"D x 19.3"W x 13.3"H - **Refrigerant:** R-32 - **Seasonal Energy Efficiency Ratio (SEER):** 14 - **Special Feature:** Remote Controlled ## Images ![Windmill 8,000 BTU Quiet Window Air Conditioner, Cools up to 250-350 sq ft - Image 1](https://m.media-amazon.com/images/I/810bN86-d+L.jpg) ![Windmill 8,000 BTU Quiet Window Air Conditioner, Cools up to 250-350 sq ft - Image 2](https://m.media-amazon.com/images/I/81OITmNgVnL.jpg) ![Windmill 8,000 BTU Quiet Window Air Conditioner, Cools up to 250-350 sq ft - Image 3](https://m.media-amazon.com/images/I/81-g0NxA0fL.jpg) ![Windmill 8,000 BTU Quiet Window Air Conditioner, Cools up to 250-350 sq ft - Image 4](https://m.media-amazon.com/images/I/81cJMwOZfaL.jpg) ![Windmill 8,000 BTU Quiet Window Air Conditioner, Cools up to 250-350 sq ft - Image 5](https://m.media-amazon.com/images/I/81V5Cj1jwkL.jpg) ## Available Options This product comes in different **Set** options. ## Questions & Answers **Q: Why isn't my unit getting cold?** A: I had the same problem with one of the units I ordered a couple of weeks ago. The first one I installed last week works great but the second one ended up just blowing warm air. I contacted the company via email (only way to engage them) last Friday evening to initiate support/return. I didn't expect them to answer over the weekend so I decided to initiate the return/replacement with Amazon. Windmillair actually responded to me multiple times over the weekend to offer help. They expressed their concern that they are having shipping channel distribution problems with carriers damaging the internals of the units. Bottom line - your unit is most likely damaged like mine was. Contact the company as soon as you can to initiate a replacement, their customer service is outstanding. **Q: Is this Energy Star Rated?** A: Hi Christopher S., Thank you for your question, and we appreciate your interest in Windmill Air. Our units test at 12 EER (Energy Efficiency Ratio) / 11.9 CEER (Combined Energy Efficiency Ratio). Energy Star is 12 CEER. We are obviously very close to this standard, and we do a lot of other things that make us more eco-friendly, like using a better refrigerant, allowing customers to shut off their units remotely through our app, and helping to offset the carbon emissions of every AC purchased.

My area gets bad from fire smoke.** A: Hi Lorene Quist, Thank you for reaching out, and we appreciate your interest in Windmill Air. The AC circulates, conditions, and cleans the air inside your room. It does not pull in outdoor air. So, you will be fine to run the AC during these tough times if you properly install and insulate your windows. We hope you'll find this answer helpful!

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 ## Frequently Bought Together - Windmill 8,000 BTU Inverter Window Air Conditioner with WhisperTech - Ultra-Quiet & Smart, Cools up to 350 Sq.
