I wanted to love this - believe me - after having a rough bad luck streak with broken air conditioners I desperately wanted this to be perfect. But sadly I’m on my second windmill AC (after the company fairly seamlessly replaced my first - points for that) and this one is just as loud and metallic sounding as the first unit. Chugs with any effort at all. I can’t afford to replace this again but I will be sleeping with earplugs all summer and getting rid of this before next season.

The unit was very easy to install. Seems to be working well and the test will be this summer to see how it handles the heat. The installation package was missing a locking bracket but I was able to figure a work around. You might want to have a follow up with your customers six months after purchase to see if the unit is working as expected.

Easy to install, app works well, quiet and efficient. BUT there appears to be a major design flaw - once the unit is cooling, some internal problem (per Windmill) messes the sensor up. It cools the room, but it keeps cooling and cooling, won't shut off unless I turn it off0, and meanwhile tells me the room is 65 (which would mean it shouldn't cool). No use having an app-controlled ac if you actually have to be in the room to make it work properly.

I chose the Windmill 12k BTU over a cheaper, different brand 12k because of the direction of the airflow, and it's awesome and so worth it. It cools the room effectively without it being a jetstream of cold air in one direction (my window is nearly behind my couch, so past ACs have directed the blast at the back of my head). The first unit arrived and had a strange rattle in it, but we installed it anyway. Within a day it froze over with an inch of ice all over the insides. Contacted customer service and they responded super fast-- walked us through a few questions and quickly determined it was likely a damaged unit. Warrantee claim initiated, and a new unit arrived within a week. Honestly I couldn't believe how excellent the customer service was. If I need another unit for another room in my house, I'm going with Windmill because I know if any issues arise they will be taken care of promptly and efficiently. My only gripe is I wish there was a little more control within the app-- if set to "cool" the unit seems to keep cooling even as the room temp drops below the set value. It would be nice if it powered off and back on later, but maybe it switches to fan only and that's enough? It could be nice to link it with a different thermostat reading too, as it's interpretation of what temp the room is at seems a bit off when on eco or sitting idle. I imagine these things might get dialed in with some software updates. I'm also a big fan of actual buttons on the unit. If I can't find my phone I can still turn it on and choose settings and temps without any difficulty. All in all, love you guys. Great product, great company. Keep it up!

It’s my first window air conditioner, so I don’t have anything to compare it to. It is heavy, so I needed to recruit a strong neighbor friend to carry it up the stairs and help place it in the window. We added a block of wood on the inside windowsill to carry the weight, otherwise the entire weight would be carried by a thin vertical piece of plastic that is my vinyl window trim. The design of my window did not allow the thinner edge of the side panel to slide into the window channel, which it appears to be designed to do. I used the provided black foam insulation to compensate for the imperfect fit and fill the gaps. We used only the center window screw and blocks of wood over the top of the window frame to prevent it from opening, so I did not have to screw lots of holes into my vinyl window casing. The internal temperature guage registers cooler than other room thermometers and my Echo device, but I plan to adjust for that by setting a higher temp. The app is simple to use and easy to install. The delivery company paid no attention to the “This Side Up” instructions on the box. It was left on its side when delivered, but so far seems ok. I have it on Eco mode with the fan set to low, so it is really pretty quiet. Great packaging and instructions; the company obviously is making every effort to make this simple for customers, even including a decent pair of scissors to cut the side panels to length. I ordered directly from Windmill and the unit was delivered in two days. The product available on Amazon is not the newer “whispertech” model, and Amazon does not make it known that there is a newer, more efficient, quieter, (more expensive) model available, which is going to make some people unhappy when they find this out. I am using this in an upper level painting studio where I and my paintings have been suffering in over 90 degree heat for at least a few weeks every summer, so I am pretty excited about the improved atmosphere. Also want to add that I really appreciate the marketing video of the person in the red outfit, which alone would make me choose this company over others.

This unit was super easy to install. Once it's all in place it is very sleek and looks so much nicer than so many other AC units. It's pretty quiet compared to a previous one we had - we like sleeping with the sound of a fan or a white noise machine, so it's perfect. We would definitely recommend!

I'm impressed with the power of this unit. It replaced a very no-name department store air conditioner of supposedly similar power, but this new one is a beast. I live in a very small, old, one storey home, so we just use two window units to cool the place. It's noticeably more comfortable and quieter than the old unit. I am actually able to set the thermostat on it to 74 instead of 68.

The upward direction that the air blows is perfect! My desk is right by the side of the unit---I'm very comfortable sitting next to it all day and all the papers on my desk stay put! It is also so quiet that I've had to check to see if it is on a few times. I had help with installation but it was a breeze. I love all the options the for changing the temperature, too. The 6000 BTU model is more than enough to cool my entire living room (250 sq ft with 12 foot ceilings)

I did a ton of research before buying an A/C. I decided to trust windmill and I was not disappointed. I had a little trouble with the AC fan at first but customer service responded in less than 15 minutes. They were attentive, kind, understandable and mostly helpful. They sent me a replacement after examining the situation and now everything runs smoothly. Always happy to support small businesses!

This is my second Windmill AC and it is perfect. Does not look as good as the advertising if you tilt your AC which is necessary. I think you should remove the scissors (not needed) A filter did not come with my second AC but I am sure this will be taken care of by Windmill.
