I have three Windmill window air conditioners and was shopping with them back when they first started selling these units. Every single one has stopped working, and Windmill has switched their policies around on repairs and replacements for faulty merchandise. The fact that all three units failed says something. The first one started leaking within the initial six months, the second completely stopped working after a year, the third gave out after three years. SKIP THIS BRAND. SKIP THIS COMPANY. They don't care about customers and they won't fix broken equipment. I filed a complaint with the Better Business Bureau and Windmill won't even reply to or take seriously any complaints people make.

Just a warning to anyone thinking about getting a Windmill AC: you might want to look at other brands instead. I bought mine back in 2023 and the control board eventually failed, which made the whole unit stop working right since it kept changing settings by itself without me doing anything. I worked through troubleshooting steps with their support team and they did acknowledge the control board was broken but told me it wasn't covered under warranty anymore. They offered me a hundred fifty dollar credit if I wanted to buy another one, which seemed pretty stingy given how fast the first one quit working.

Like others have mentioned, my Windmill unit started losing performance after a couple months. When I reached out to customer support about it, they just shipped me a replacement without actually investigating the underlying problem with their units. The next summer I pulled it back out after storing it all winter, and wouldn't you know it, same problem showed up again with no software updates or improvements to speak of. On top of that, the unit was leaking condensation inside the case instead of draining properly out the back. I ended up eating the cost on this one. Definitely do your homework before purchasing.

Got myself a 12K BTU Windmill AC from a big box retailer at the end of May 2025. Around six weeks in, it started shutting itself off every five to ten minutes and never cooled my space right after that. Then right before an intense heat wave hit, the thing gave up completely, which is when everything went downhill. I called Windmill support right away and gave them absolutely everything they wanted: my serial number, proof of purchase, photos of how I installed it, my room measurements (500 square feet), plus I confirmed doing their troubleshooting steps. They said it would get bumped up and I'd hear back in a day or two. What actually happened was more than fourteen days of waiting, asking for the same info over and over, and getting nowhere. They kept questioning whether my room was actually 500 square feet like I kept telling them, and pushed me to send video proof of it not working even though I'd already removed and swapped it out just to keep things cool inside. Pretty hard to film a unit that's broken and does nothing. At that point I contacted my credit card company and reversed the charge, then bought a different one myself. Windmill's parting shot? They shut down my support ticket and told me I'd been disrespectful after I spent two weeks trying to get them to honor the warranty while dealing with ninety-degree heat.

Really happy with my two window AC units, and I recently picked up their air purifier too which I'm loving just as much. The window units are fantastic, they pump out cold air super fast for my bedrooms and that's exactly what I want since I sleep best in a really cold space. They barely make any noise and look sleek which matters to me. I've also noticed my power bill went down noticeably. The purifier is excellent as well, food smells don't hang around my kitchen anymore and my seasonal allergies are way better, I hardly ever sneeze now when I normally would at this time of year. Really impressed with everything they offer.

Just grabbed a Windmill AC plus their air purifier and I'm really impressed with both. Quality feels great, they both work as advertised, and the design is really appealing. Being able to manage both units through an app is super convenient. Their support staff answered my questions before I even bought anything and they were quick and knowledgeable. Couldn't ask for better overall.

This AC unit is seriously a total game-changer! It cools down a room in basically no time flat and makes the space feel like you're in a high-end resort. Barely any noise at all, uses way less electricity, and the install was straightforward and simple. What else would you want? If you're going back and forth about it, just buy one. You'll be glad you did.

These folks really back up what they make, and that's getting harder to find these days. My window air conditioner from them is solid. Honestly it's the best window unit I've owned in a long time. My previous one basically died when I took it out and put it back in after winter.

Had an absolutely fantastic time with this company. The person handling my support request named Lois really went above and beyond. The AC itself runs super quietly and I had zero trouble setting it up. Major thumbs up to the Windmill team!

My unit went out after eighteen months. Could be they're building them to fail quick, could just be poorly made. Not very environmentally friendly like they claim, since their stuff can't be fixed and ends up as garbage after a short while. Mine is showing an E2 error code and customer service already sent me their formal apologies. Well, I'm going to make sure everyone on social media knows about this so they never get a moment of peace. There's absolutely no reason to keep selling products that break down and end up polluting the environment.
