Great AC unit with smart features and easy installation!

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!

Great cooling solution

I love my window unit. I have a Cape Cod, and the upstairs bedroom is too hot to sleep in during the summer. It also isn't a ton of square feet. The Windmill AC I bought is the perfect size. It is sleek, effective, and so efficient that I don't notice a huge difference in my electrical bills in the summer. I am really satisfied with it.

Great ACs and Customer Service

We've purchased 4 Windmill ACs over the years, replacing the old ones our apartment had installed. We've tried several of the older and newer major brands and Windmill is easily the easily the best combination of quiet enough to sleep with, quickest to cool a room, convenient (controlling and programming from their easy to use app), and best looking inside and outside (not so important but a welcome tally). Additionally, their customer service and warranty/replacement policies are great. Windmill's ac's work really well consistently, but nothing is perfect—when one of our machines inexplicably stopped working they replaced it really quickly (within two days!) at no charge. It's always nice to be able to support a small business when you can and it's even nicer when their products a great and they back it up.Oh, and reply to the owner's, Mike's, emails, he'll respond and help out when needed!Very, very easy to recommend Windmill.

Exactly what I was hoping for

I purchased this window air conditioner because my husband and I like to keep our bedroom cold at night for sleeping but I didn't want to waste energy cooling down and heating up our whole house. This was the perfect solution – easy to install without any special equipment and way quieter than any other window air conditioner I've ever used. We went with one just a little more powerful than we needed for our space because we wanted the quieter motor and I'm happy with our choice. I also like that it will be easy to take with us to another house if we move again since it is not a permanent installation.

Fantastic Product

As a Coloradan, migrating to New York City five years ago was... sticky. Pretty sure I'd never experienced heat, humidity—ALL of it like it was in NYC. And to top it off, he's a hot sleeper!! I tried serval units over several years until I finally found the one... Windmill! I'd still have it many years later if I hadn't moved into a building w central air. THANK YOU WINDMILL

Best window AC ever!

I've gone through many window AC units but Windmill is by far the best. The installation is seamless and easy since the unit itself is so sleekly designed, no rough or sharp edges that could scrape you. Having it be able to pair with a phone app makes its use that much simpler, it's really a breeze. And it's so much more quiet than any other brand I've used. You can finally hear the TV even when the unit is on full blast, which is something that we used to overcome by using close captioning because other brands were so loud. We have 2 Windmill units now, one for the bedroom and one for the living room. If we ever needed another we would for sure get it from them. We can't recommend Windmill enough.

love my upgraded AC!

I've been using windmill ACs for several years now, and a major plus is that I can control the unit via the phone app even when I'm not home. Not only does it work well, the design of the AC looks beautiful in my apartment. I used the original model (6k BTU) for 3 years, but after moving last year I decided to get the new WhisperTech model (8k BTU) and am super impressed with how much quietier it is and how quickly it cools my home. The customer support has always been fantastic as well!

Best Window AC I've Ever Had

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!

Great A/C

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.
