We opted for the whisper technology upgrade. It’s very easy to install- my husband had ours installed & set up & running in less than 20 minutes. It is SO quiet- husband says it’s bad because he can now hear the rain on the unit- it’s fine he is NOT a light sleeper! And COLD! We thought our old one was cold… but apparently not so much! Our previous unit was 17 years old and ran fine until we bragged on it- then POOF it stopped working. Things have definitely changed in 17 years! We are still in our first week of ownership, but we like it, and the app is sweet!!

I was looking for a clean, minimal style air conditioner that wouldn't take up a ton of room or make a lot of noise like my previous units. My new Windmill unit has been a dream. It's modern, stylish, and the noise level is low. I also love controlling it from the app when I'm out and coming home. Highly recommend!

Overall this is a fairly nice AC unit for the price point—it looks better in my room and is quieter, than many AC units. However, the temperature gauge—which measures the ambient air temperature in the room—is often incorrect. This is a problem because it means that it thinks the room cooler than it is and won’t turn on. I reached out to Windmill about this issue and they responded acknowledging the issue and basically suggesting I try and mess with the temperature gauge myself, by insulating it, to fix the issue. Not impressed that they are selling an AC unit that they know has this issue.

We ordered three Windmill window units for our new NYC apartment (living room, master bedroom, kid's room) and we are so happy! Our super installed them so can't speak first hand to ease of installation but it didn't take him too long to do all three. The product looks sleek and way nicer than the (traditional, old, uggo) units we had removed. We love the app functionality and the ability to share control among household members.

The AC box itself is very pretty and SUPER quiet. The installation guide isn’t reaaally well suited to windows with storm windows, but with some shims we made it work. It would also be nice to get a little more insulation. We used a couple extra towels we had lying around to get things really insulated. All that said, the real reason i’m giving this 4 instead of 5: it doesnt turn off on eco mode, even when the room is 10 degrees colder than what it’s set to. Its temperature gauge will even show that it’s well below the threshold, but it wont shut off, not even intermittently. Not very ecofriendly or energy bill friendly :(

I bought one 10K unit to see how it went, loved it, bought a 2nd 10K unit, love it too! They are extremely easy to install, and these 10K units are more compact that typical 10K units and fit great in my smaller windows. The cover on the condenser fins prevents your fingers from getting sliced. They're definitely quieter than my old 10K units and don't interfere with TV or conversation, but they're not silent. Phone app works great! Automation settings work great! Very happy with these units.

Amazing little ACs. Pretty in my apartment and being able to turn them on from anywhere with my phone really helps! I travel a lot so being able to cool my apartment down from the airport so it’s nice when I get home is a game changer! I have one in every room!

love the clean looks, airflow design, intelligent controls and quiet operation. Bought three units and one failed after a week....BUT tech support diagnosed on a Sunday and had replacement by Thursday....impressive ! Would like to see settings return to last rather than default to ECO

The Windmill 8300 BTU works great, is packaged well and super easy to install. This is definitely the least amount of work I have ever done to install a window AC unit, so super convenient. I did have an issue with my first unit, the compressor didn't work but the company quickly resent a brand new unit and one of the founders reached out to make sure it was sent priority. Ill give this 5 stars because its tough to complete with the established manufacture's and they clearly care about their product quality.

I’m so happy with my AC! It’s so clean looking and quiet. The app works really well and Alexa pairs with it quickly and easily. But honestly, the icing on the cake was the customer service! Someone got back to me within minutes of an email. If my apartment was bigger I’d get more! So worth it.
