I live in 100 year old building with 4 exposures (n,s,e,w). We have to rely on AC units to keep our apt cool. We bought 3 units and it has seriously helped. The units are understated, not obnoxiously loud and best of all the app woes quite well to turn the units on before we get home. It's so easy to program them to turn on and off that it almost feels like central air because when we come home it's actually cool! I had an issue with one unit and the customer service was also great. Stand out product and buying experience.

This AC unit was so easy to install and was so quiet that I ended up buying a second one for my son's room. I bought the smallest one for his room and its so quiet and perfect for his small nursery. Also that fact that I can control the AC unit from my phone helps when the temperature changes drastically in his room and I don't have to sneek into his room while hes asleep. Wonderful unit!

Excellent product and outstanding customer service! The AC does a fantastic job keeping the room cool. What truly impressed me, though, was how responsive, and helpful the support team was after I contacted them about an issue I had. They were kind, attentive, professional, and truly committed to helping/making things right. It's refreshing to see a company that truly cares about its customers, and stands behind its products. I'm beyond satisfied, and would highly recommend them to anyone looking for a reliable AC, and outstanding support!

This is such a top notch air conditioner it’s unbelievable. The app makes it so convenient to use and turn on before I’m getting ready for bed or whenever I get home. Also the air blowing up instead of out genuinely cools the room so much more. I have a very large master suite and it cools it down so well. Plus the look of it?? Amazing. It’s so seamless and not the bulky and ugly window units you are used to.

The Windmill is the best window AC unit I've ever had. It looks great, is easy to maintain, has a good mobile app to control it remotely(not required, but useful), is easy to maintain, relatively quiet, and my favorite feature is that it blows cold air up, not out, so placing it in a window near a chair, seat, bed, etc. is much more comfortable than traditional window units. If you need a window AC, I'm not sure there is a better one on the market!

I needed to replace a 15-year-old 5000 BTU A/C this summer since it wasn't cooling as effectively (and my town offered a rebate for recycling inefficient appliances). I'd seen ads and reviews of the Windmill, so I convinced my wife to let me order it. The install was very easy. The most difficult part was taking out the old unit. Controlling the unit via the app is easy, and I like the energy use meter. We also go out of town once a year, so the ability to start it the day before we return is very helpful (much better than returning to a 90°+ house). I also ordered one of the interior covers, and it's doing a great job of keeping the cold weather from getting in during this winter storm.

Had a few AC's over time and when it was time to replace I tried checking out the Windmill site.Picked out one that looked good and small for a NYC apartment with and was fair priced.When we got it, getting it into the window was super easy, and it looked great but let's turn it on....When this was going on NYC was in the middle of a heatwave, so we got it just in time, and once we turned it on we wore pleasantly surprised at how quiet it was and even better, during a heatwave how fast we wore cool and comfortable.So if you're thinking of getting a Windmill from me it's an easy “YES!”

Living in Manhattan, we have always had in-window air-conditioning that has worked to varying degrees of success from other brands. Windmills AC unit worked as expected, and the integrated app was extremely useful and user-friendly. It wasn't hard to install by myself. We ended up getting a second for our spare room shortly after testing the first. Living through the extreme weather of New York didn't feel like a challenge at all. Highly recommend. Oh, also, their customer service is phenomenal in my experience. There was an issue with our second unit, but once I shared the video of the noise it was making, they rushed shipped a replacement. Tryuely felt like they cared about their brand.

I have 3 Windmill AC units, they're all quiet, efficient, and a breeze to install! Replaced older (not too old) traditional window ac units, these inverter units are significantly quieter, and cost effective. We can sleep at night with the unit going in our bedroom, and the smart app makes using them a breeze.Thanks Windmill!

Even though I had a new HVAC system installed, I was still uncomfortable upstairs, in my 1925 home. None of my friends had heard of Windmill before, but after I read a review on Wirecutter I decided to try one for my bedroom. It arrived quickly and it was light enough that I could carry it upstairs myself, with little effort (69 y.o. female). In less than 30 minutes, with a little assistance from my teenage granddaughter, we had it installed; it quickly & quietly cooled my upstairs, beyond the bedroom I purchased it for. This is almost so easy to install that one person could do it, but due to the original, 100 year-old windows it required two people to keep the window propped open. Placing and securing it was simple. I love that the vents blow upward and not directly on me. You can hear it cycle on, but I find it no more noticeable than my central a.c. and it does not interfere with my sleep. I'm very pleased with my purchase & the comfort it provides through the sweltering summer months.
