Windmill 8,000 BTU Window Air Conditioner - Quiet & Smart, Cools up to 350 Sq. Ft. - Easy Install No Assembly, App/Wi-Fi, Voice-Enabled, Remote Control

We’ve been so impressed with our Windmill AC! Installation was incredibly easy, everything was clearly laid out and took hardly any time to set up. The design is sleek and fits beautifully with our space. One of the best parts is how quiet it is, we can barely hear it running, even at night. The companion app is a game changer too: being able to pre-schedule the temperature from our phones makes everything super convenient. Highly recommend!

I have owned this unit for. week ----easy install and looks excellent in my window--some how it is not obtrusive and the remote works flwlesslyover the years I have owned a lot of room air. conditioner and this one is the best yet. Get it, you too will be happy--It is made in USA---what a thing that is.....Oh very low noise and easy to use

The windmill unit is amazing and 10k btu is a must. A consistent cool air since installing has significantly helped us to avoid those unexpectedly hot days and keep good airflow in our apartment that doesn't have the best ventilation. It's quiet and easy to use. One issue with Wi-Fi connectivity but all it took was hitting reconfigure on the app!We've been considering an AC unit to help supplement our building fan HVAC in the shoulder seasons. TLDR, on hot spring days before the building switches to AC our east facing windows can make our apartment 80 degrees or warmer. We didn't want a big ugly unit so windmill was always a brand we were eyeing. I can confidently say it solved both our problems with 1) a sleek design that maybe even adds to our apartment and 2) a quiet but effective strong cold air flow.10/10 would buy again.

Windmill Window AC Unit Review: A Disappointing LetdownI had high hopes for the Windmill Window AC unit when I picked it up as a replacement for my trusty Midea U-shaped window unit (which I gifted to a friend in need). Drawn in by its sleek aesthetics and promise of efficient cooling for my 250-square-foot bedroom, I was ready for a worthy upgrade. Unfortunately, after extensive use, I can confidently say this unit falls far short of expectations. From a flawed temperature sensor to excessive noise and a laughable "Eco" mode, this AC has left me frustrated and regretting my purchase.Let’s start with the biggest issue: the temperature sensor. This unit struggles to accurately detect the room’s temperature, and I’ve confirmed this with multiple independent sensors placed both near and far from the unit. Consistently, they read 5-8 degrees higher than the AC’s set point. This isn’t a matter of insufficient cooling power—the air blowing out is ice-cold and refreshing—but rather a fundamental design flaw. After digging into the unit’s construction, I pinpointed the problem: the sensor’s placement is a disaster. It’s affixed right next to the evaporator coil, the coldest part of the AC, where incoming air is sucked through. This means the sensor is constantly bathed in frigid air that doesn’t reflect the actual room temperature. As a result, the unit misreads the room as much cooler than it is and shuts off prematurely, leaving me sweaty while it smugly assumes its job is done. There’s no DIY fix for this—it’s a baked-in flaw that undermines the entire system.This poor sensor placement doesn’t just mean an uncomfortable room; it also leads to constant cycling. The AC turns off too early, then kicks back on when it finally realizes the room isn’t cool enough. This on-off dance increases energy usage and creates more noise—two things no one wants from an AC unit. Speaking of noise, let’s talk about that next. Compared to my old Midea U-shaped unit (same 10,000 BTU capacity), which was whisper-quiet on low settings and pleasantly soft even at max power, the Windmill is a letdown. You can hear the compressor rumble to life with every startup, and the fan noise is choppy and grating, likely due to friction with the grill. Worse still, its traditional box shape offers zero sound insulation from outside noise—it’s like having an open window. My Midea, with its U-shaped design, kept the window itself as a barrier, muffling street sounds effectively. With the Windmill, every car horn and barking dog comes right through.Then there’s the so-called "Eco" mode, which is honestly a joke. All it does is turn off the compressor and cycle the fan every 20 minutes or so to check the temperature—except, of course, it relies on that same terrible sensor. In normal cooling mode, air is at least drawn over the sensor from the room, giving it a fighting chance. In Eco mode, with no active airflow, the sensor sits next to the cold coil for ages, reporting absurdly low temperatures (like 58°F) while my own sensors clock the room at 70°F. The result? The AC stays off far longer than it should, letting the room heat up while it pats itself on the back for “efficiency.” It’s a feature that sounds good on paper but fails miserably in practice.Adding insult to injury, the unit comes with carbon “filters,” but they’re a complete letdown. As you can see from the image, they’re a tiny fraction of the size of the dust filter; and they’re made of low-quality carbon-coated fiber, not even real carbon pellets that would actually trap odors or impurities effectively. To top it off, Windmill sells 3-packs of these flimsy filters for $45 on their website. That’s right—$50 for what feels like a marketing gimmick masquerading as a feature. It’s a joke, especially when you consider the minimal air purification they offer and the outrageous markup on such a subpar product.To make matters worse, I tried reaching out to Windmill about this last year. I emailed them suggesting they add a temperature offset feature to their otherwise solid app (which, I’ll admit, is sleek and user-friendly). Here’s the deal: the sensor often reads the room as cooler than it really is—like showing 60°F when the actual room temperature is 70°F because it’s too close to the cold coil. If I set the AC to 65°F, it thinks the room’s already at 60°F, below my set point, so it stays off—leaving me hot. An offset would let me tell the AC to treat its 60°F reading as 70°F. Then, when I set it to 65°F, it would see 70°F, realize that’s too warm, and start cooling. It’s a straightforward software tweak to fix their hardware mistake, but all I got back was a vague “We’ll pass it along to our team.” A year later, there’s no update, no offset, nothing—just silence. It’s frustrating they’d ignore such an obvious fix.In short, the Windmill Window AC unit is a stylish shell hiding a poorly executed core. The aesthetics that lured me in can’t make up for its inability to cool effectively, its noisy operation, or its energy-wasting quirks. If you’re looking for a reliable, quiet, and smart window unit, look elsewhere—my old Midea was proof that better options exist. I’m disappointed I traded up for this, and I can’t recommend it to anyone who values performance over looks. I plan to somehow sell this unit and buy another Midea. Do not make my mistake, buy Midea.

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.
