My 6,000 BTU Windmill A/C was replaced by Windmill even though it was a couple of months out of warranty. It had an E2 error that, even though the unit blew plenty of cold air, I could only control it with the remote or Android app. Customer service was helpful in walking me through the troubleshooting process and when I was unable to clear the code, the said they would send a new unit. It arrived in a couple of days. THAT IS GOOD COMPANY SUPPORT. And while I was disappointed that the unit threw a code at all, I was thrilled at the positive company response. You won't get that with LG or GE. Nope.

The Ac is quieter than anything else that I have owned. The installation is as time consuming as any other window AC. The side brackets are ok but can only be used once as you have to cut them with the scissors to make them fit re-installing them would not work.

I absolutely LOVE this product and would highly recommend.This AC window unit is sleek and modern looking but still gives off enough air to cool down the living room. I’m thinking about purchasing another for the bedroom. I hired a task rabbit to install, although it looked easy enough to install myself, in which the Windmill AC website had a direct link to book and had directions listed in the task description already for you. It was super simple and took the tasker 15 mins to install. He was also already familiar with the installation which made me feel comfortable. Overall, from purchasing, delivery, and installation I was super impressed with the entire process! 100% worth the investment!

I loved my Windmill AC, but not long after I bought it, the ground to the plug broke, rendering the unit unusable. After contacting customer service, I was delighted when they assured me that they would send me a new AC, and it arrived in less than a week. Not only is the product fantastic (quiet, and perfectly chilling), but customer service is fantastic. Wholeheartedly recommend!

This company is honestly better than all the other major manufacturers we've purchased from. When our unit encountered a technical issue after a winter in storage, customer service stepped in and almost immediately resolved. A new unit was arriving at our door before we even realized it. A huge relief and a great experience! And we LOVE the app-enabled product. Being able to set our times & temps away from home has made such a difference to our comfort. Knowing our dog is safe when we aren't home and it won't over heat does us so much good. Wouldn't recommend you buy anywhere or anything else.

Love my WhisperTech air conditioner so much that I bought two. They are so easy to install and do a great job keeping my rooms cool. One unit I received rattled a bit, but customer service was quick to replace it for me. Excellent service team - everyone was so responsive and helpful.

Outstanding product! Super easy to install! The new 10,000 btu Windmill does an excellent job of cooling my entire 850 sq. ft. home! Happy Happy! I did have a couple of questions that were answered by the excellent customer service team! Fast & thorough! Thank you!

The Windmill AC is a beautiful and easy-to-use product. They've considered every detail when designing this product, from the unboxing experience to the hardware itself. The materials feel high-quality and durable, which is important for a piece of equipment that runs daily such as an air conditioner. My only complaint was that I did not realize there were two different iOS apps based on when the AC was made, so that caused some confusion when I tried to connect the AC to wifi. Otherwise, it is a fantastic product that performs well.

This is by far the quietest air conditioner I've ever owned. And it's very efficient. The house is very cool without all the noise. It looks beautiful and was very easy for the Task Rabbit installer to put in. I plan to upgrade both air conditioners for the bedrooms next year.

Set up was pretty straightforward , and actually easier than my old window units. I am still unsure how to install the carbon filter : there was no illustration or description of which side of the filter should face outward/inward. Other than that, it was easy breezy!
