Bought a Windmill AC unit that developed a serious fault: the button/display board connection started misfiring, causing random mode and temperature changes and nonstop beeping, even climbing to 86°F on its own with no input from me. After some digging, I found this is a known issue going back to 2022 units, still being reported recently, so it's clearly not an isolated defect. Email support was a letdown. I couldn't provide original proof of purchase (got the unit secondhand) and was flatly denied any warranty help. After reaching out on Instagram, a rep offered $100 off a replacement, which I appreciated, though it still felt light given the retail price and how widespread this issue seems to be. In the end I fixed the unit myself by disconnecting the faulty ground wire, thanks to the Reddit community that clearly had to figure out on their own. Product function when it works is fine, but the recurring hardware defect and inconsistent support experience make it hard to fully recommend without reservations. I was drawn to the design, but the quality of the product is not worth the price as I am now viewing these as disposable products that the company doesn't stand behind.

Bought a Windmill 6K AC unit in June and it started showing a sensor error within weeks. The unit now refuses to turn on in Eco mode if set below 81 degrees — making it basically unusable as an air conditioner. I've spent weeks going back and forth with their support, sending screenshots, following every troubleshooting step they asked for, and even providing serial number and shipping info. They keep repeating the same tests and making excuses instead of honoring the warranty. Extremely frustrating experience. Do not recommend. Company is listed as an F on BBB.. DO NOT BUY FROM THEM.

I spent $500 on a 12k BTU two years ago. It was working great! Until it stopped working completely today, a 90 degree day. Windmill walked me through hours of a hard reset to ultimately tell me there is nothing they can do but offer me a code to buy a new one at a discount. I previously wrote a glowing review here because I enjoyed the ac so much but to only last two years is simply unacceptable. My cheap and old Haier lasted me 12 years and was still going when I gave it away! I tried to shop a small company but their product simply doesn't stand up to time. Save your money and buy another brand.

This air conditioner got great ratings...clearly they were falsified! The "Smart" app does not connect and the machine changes it's own setting and turns itself off when it wants.

Just garbage. The reviewer that said it blasts ice cold air in seconds must have been high or just making stuff up. I purchased the AC unit early on. It was malfunctioning so they sent me another one, almost suspiciously quickly, like they knew they were selling faulty gear. A couple years later and neither one does anything close to cooling off a room unless you keep the door shut and let in run for 12 hours.

I purchased a Windmill Air purifier directly from the company in 2025. It was expensive. Now, less than 2 years later the unit just stopped working. At first i was impressed with their customer service— they responded immediately. But then they asked for the same photos and same information repeatedly and I realized that i was talking to AI. After the 4th request for the same pictures and same information i told them enough. After i did so a real person replied to me and informed me that the company was sending me a new machine. So frustrating experience at first but their customer service came through.

App refuses to connect, the unit changes settings on it's own, poor performance.

It is near impossible to responsibly dispose of windmill AC units in NYC. They link you to DSNY on their website but DSNY does NOT accept their AC units due to the refrigerant. Windmill has no other solutions for disposal. I am looking at $150-200 removal from a private company.
