What makes Windmill unique?

We combine decades of AC knowledge and manufacturing experience with a modern approach to deliver a better window AC, built from scratch. Our units are beautifully designed, powerful, quiet, smart, and easy-to-install (we pre-assemble the installation kit for you, so it's ready to go out of the box). If you need a little extra assistance, we've partnered with TaskRabbit nationwide.

We also offer a carbon filter subscription to help keep the air in your home clean. And, our units are eco-friendly. We use an eco-responsible refrigerant called R32, help you recycle old units, and help offset the carbon footprint of every AC purchased.
