Installation instructions.

I haven't bought this yet, but can't wait for it to get here, because it's hot as heck in NYC currently. I like the advertised 'easy install', but the installation video on the product site left me uneasy -- there should be at least two people installing this AC in the AD!
I would recommend this to a friend!

Still great, still cool

It's a billion degrees fahrenheit currently, so we upgraded from the OG to the 12k beefy boy. Absolutely worth it. I can sleep without waking up in a makeshift swimming pool of sweat

Pleasantly Surprised

After long hours and sleepless nights of doing research, we decided to try the windmill AC with whisper Tech. Suddenly, our sleepless nights ended! These things are so quiet when set on low cool you would think that you're listening to a gentle rain on your roof. We really appreciate the fact that this machine works exactly as described, so much so that we bought a second one for another room in our house! The app is user friendly and easy to navigate. Cleaning the filter is a breeze compared to other machines we've had in the past. One of the extremely pleasant surprises, was the customer service. Their first machine we bought came from an authorized third party. We can't be certain but we think the machine may have been mish-handled and shipping. However, the support team at Windmill stepped up to the challenge. We had a new machine working perfectly in no time at all! Don't let our review convince you. If you want the room to feel like central air conditioning from a window unit, this is the one to buy.Sincerely, Spencer

900SqFt no problem. 😎

12k unit has had no issues cooling my entire apartment with the support of fans. The app has functioned flawlessly and the installation was a breeze. It took roughly 16hr to reach the furthest points away from the unit but 71-74 ° F has been maintained in 80-95 ° F outside temps. Thanks for ending this Michigan heat wave, maybe I don’t need central Air after all! WeOne star less only because the packaging was obviously an AC unit that could be spotted from a distance away.

Easy to Install. cools the room. I haven't had other units in that room, so I can't rate the noise one way or the other.

Good experience eventually

TLDR: Our brand new AC never worked, I had a frustrating experience initially with customer support, but I did get a replacement AC eventually and that works. We bought a 8K BTU Windmill AC on Amazon. We got it installed two weeks back. Then in last week’s heat wave, we turned it on and it did not work. Must have had a bad compressor. I reached out to Support on the site’s chat and they assured me they would prioritize sending and installing a replacement because of the heatwave. I also emailed Support and they too assured me that they would reach put regarding the replacement. I didn’t hear anything for a day. Followed up, and still didn’t hear anything. Basically I was ghosted. Then I got an email saying they will send a new one, but not install. I had had to pay a lot of money for the installation. So I sent them the promise I had got that it will also be installed. Then I was ghosted. Finally I sent a stern email saying they could refund me the money for installation and just send the new AC. Then I finally got a response. They sent a replacement and gave me an Amazon gift card for the installation. It arrived quickly (via Fedex) and it was installed and this one works. It looks great. I was very frustrated last week because I was left stranded AC-less during a heat wave and was just plain ghosted. But, the company stands by its warranty and sent a replacement. I am impressed by that and grateful. Thanks to Maggie who responded and took care of everything. I understand that machines don’t always work but a company that stands by its products deserves appreciation.

Replacement unit

I cannot thank the windmill team enough for their help with a service issue. Everyone was nice, responsive and knew the a/c system well. When we found we could not repair, customer service reached out and replaced our unit. AT. NO. COST! Virtually unheard of. We went with windmill originally because we wanted a smart a/c (controlled on smartphone and Alexa) and a unit that was quiet. We are staying because of the care we received when we needed help. We will not go anywhere else for our cooling needs. It is only 95 degrees today. 🥵 But later this week we can’t wait to see temperatures reach 105 and hotter. We will be watching it all from our frigid bedroom. Thank you Skye, Maggie and Mike!
