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
