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.

My 8000 btu ac unit stopped working randomly. It no longer cools and constantly cycles through different modes making it beep over and over. Customer support has been less than helpful. They should not be allowed to keep selling these units.

Considering the price point, this air unit is incredibly disappointing. It doesn't really cool the 1 bedroom I have it in at all, and the buttons have started glitching making it virtually unusable. Customer service has refused to offer any solutions other than a $100 voucher towards a new unit. I've heard in terms of more expensive ac units, Midea is the way to go. That being said, my $20 LG ac unit off of FB marketplace was far more effective and still works perfectly.

I have 3 Windmill window a/c units, I was one of their very first customers when they came onto the scene for window a/c units. All 3 of them have broken and now Windmill has changed their policy in terms of repair and replacement for their broken units. The fact that all 3 of my units have broken is a warning. The first one was leaking fluid within the first 6 months, the second one stopped working completely after 1 year, and the 3rd one stopped working after 3 years. DO NOT BUY. DO NOT TRUST THIS COMPANY. They do not care about their clients, and they will not repair broken units. I have reached out to the BBB and Windmill doesn't even address or respond to any negative feedback about their company.

Just a heads-up for anyone considering a Windmill AC unit: I’d recommend looking elsewhere. My unit, purchased in 2023, developed a control board failure that made it completely unusable — it started randomly changing settings on its own.

After going through troubleshooting with Windmill support, they confirmed the control board had malfunctioned but said it was outside their warranty period. Their only solution was to offer a $150 credit toward buying a replacement unit, which felt disappointing given the short lifespan of the original.

I have had the same experience as Steve Gray, the Windmill product I had stopped working efficiently after two months or so and when contacted about the issue they just send a replacement rather than looking into changing anything about their faulty devices. I tried using it again the following summer after sitting in storage and it still had the same issue without any sort of update to their software or device functionality. It also leaked condensation inside rather than dripping out the back. I ended up just taking the loss, buyer beware.

I purchased the 12K BTU Windmill AC from Best Buy in late May 2025. After working for about six weeks, it began shutting off every 5–10 minutes and never cooled properly again. Right before a brutal heat wave, it completely failed — and that’s when the real nightmare began.

I contacted Windmill support immediately and provided everything they asked for: serial number, receipt, installation photo, room dimensions (500 sq ft), and confirmation that I had tried their reset steps. I was told the issue would be escalated and I’d hear back within 24–48 hours.

What followed was more than two weeks of delays, repeated requests for the same information, and zero meaningful help. They kept asking if the room was really 500 sq ft (yes, four times now), and insisted I send a video of the unit “not working,” even after I had to uninstall it and replace it just to keep my family cool. It’s hard to film a broken product that does nothing.

Eventually, I gave up, filed a chargeback with my credit card company, and replaced the unit myself. Windmill’s final response? Closing the case and accusing me of being disrespectful — after two weeks of me begging them to honor their warranty while roasting in 90+ degree heat.

This company does not stand behind its products. Their support system is slow, repetitive, and clearly designed to wear you down until you stop asking for help.

Avoid Windmill at all costs. If something goes wrong — and judging by other reviews, it often does — you're on your own.

I love my two window AC units and just got the purifier which I also love. The window units are amazing, they cool the bedrooms so quickly which I love because I like to sleep in a very cold room. They're super quiet and look amazing which is important to me. I've noticed my energy bill is much lower as well. The purifier is great, my kitchen never smells like food and I rarely sneeze, usually this time of year I have allergies. Big fan of their products!!

I bought a Windmill AC and Windmill Air Purifier recently, and both products are amazing. They're high-quality, do their job well, and I love the look and the fact that i can control both from the app. Also, I had questions for their customer support team before purchasing and they were very responsive and helpful. 5 star experience all around

This AC is an absolute game-changer! Blasts ice-cold air in seconds and keeps the room feeling like a luxury hotel. Super quiet, energy-efficient, and easy to install—seriously, what more could you ask for? If you're on the fence, just get it. You won’t regret it!

This team stands by what they designed and built… don’t see a lot like that anymore. Happy with the window air conditioner overall. It’s the best window AC I’ve had in years (my last one quit on me when I reinstalled it for the spring).

Absolutely loved my experience with this brand. Lois from customer service was incredible... and my AC unit was quiet and easy to install. Go windmill air!

Mine broke after 1.5 years. Maybe it’s planned obsolescence, maybe it’s just a piece of junk. Not very eco friendly like they’d leave you to believe; instead their products are unrepairable after just a short time. Mine reads an E2 message and customer service already gave me their sincerest apologies. Sincerely, I will be haunting them on tiktok, instagram, and youtube so that they never know a moment’s peace. There’s just no excuse for making crappy products that wind up in landfills.
