The WhisperTech A/C was very easy to install. The mobile app is very easy to use and convenient to turn A/C on to cool off space before arriving home. There were some glitches with loud noise from original unit. Customer service is superior, even though only email contact. Response time is almost immediate and highly focused on problem solving. When the problem could not be solved, a replacement unit was sent out immediately, and return label provided for original unit. The replacement process was seamless. I would not hesitate to purchase another unit. I wish FedEx was as competent with delivery. The WhisperTech is definitely worth it as far as a quiet unit even on high setting.

I recently purchased 2 Windmill air conditioner units. They were very easy to install without taking up a lot of space. The look is very sleek. The units cool our entire home and are so quiet I don't even notice they are running. Unfortunately one unit was damaged in shipping. I contacted Windmill by emai and they responded immediately with a solution. Within days I received a new unit. I would highly recommend Windmill air conditioners, not only for their quality and efficiency, but also their outstanding customer service.

I really like this AC. It’s quiet and has a modern style. Easy installation with very good instructions. My family enjoys looking at it. It has great features to accommodate to your comfort. I usually remove my AC units in the winter but this AC I will keep it on my window because it comes with insulation pads.

I had an older, louder AC and needed the ability to control it from my phone during heat waves in LA. Windmill checked all the boxes and the design is minimal and blends nicely with the decor in my bedroom. Love how quiet it is. I would need to turn off my old one just to hear myself think again but with Windmill I can leave it on for a long time and forget it’s on. Overall a great purchase so far.

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.

Beautiful unit, aesthetically as well as functionally! Quietly powerful! The installation was a breeze and the installation kit was thoughtful as they provide everything you need…including scissors. The support staff is very responsive and they will guide you until you are completely happy with everything. This is truly a great air conditioner and company!

I got the 6000 btu to keep my room cool, I’m super happy with it. Looks good, works well and it’s pretty quiet. The installation was easy, if you can lift some weight. I love that you can control the temp from your phone, such a great feature for pets.

It cools my office very well. It was heavier than I thought it would be but I still managed to install it myself. It looks nice and sleek. I will say the instructions ask you to screw it into the window but that doesn’t work with vinyl windows the plate to secure the window to not open farther also wouldn’t work with my windows. That said it seems very secure with the window down.

This past summer I had an issue with my Windmill AC, which stopped working unexpectedly . I tried every which way to troubleshoot with the help of customer service. I couldn't get it to work and it was no longer under warranty. To my surprise, the company replaced my unit at no cost! Their customer service was outstanding, and they went above and beyond to make things right. Not only is the product excellent—sleek design, easy to install, and operates smoothly—but the company’s commitment to customer satisfaction truly sets them apart. Highly recommend!

The Windmill team was super supportive and helpful when my original order went missing. Once I received the replacement, I was happy to start using it. It's powerful and useful in my third floor studio apartment and is aesthetically way better than any other window AC option that I've found.
