Energy Guide
Find out if Windmill is right for you
We put in top vents that blow air up and out into the room at a 45 degree angle (and not into your face, like other window air conditioning units). The result is an in-window air conditioner that delivers better air flow and more efficient cooling.
Not only do our insulation panels look refreshingly clean, they also keep out outside air. In the summer, that means a more comfortable home with higher energy savings. In the winter, that means you can leave our low-profile window air conditioner in year-round (and avoid the hassle of removing and storing your window AC).
Control your smart window air conditioner with our app, for iPhone and Android. Turn the window AC unit on 10 minutes before you get home on a blazing hot day. Turn it off if you forgot you left it on (now that’s eco-friendly!). You can also connect your Windmill in-window AC unit to Google Assistant and Amazon Alexa for voice control.

We didn’t want to create another window air conditioner that’s bad for the environment. We use a responsible, eco-friendly refrigerant (R32) with 68% less global warming potential than what’s commonly used (410a). We also offset the carbon emissions of every window AC unit purchased. We'll even help you recycle your old window air conditioners.
With curved edges, clean lines, and an auto-dimming LED display, Windmill blends right into your home (without bright LEDs keeping you up at night).
Fresh filters mean fresher, healthier air, plus improved performance and longevity for your AC. We’ll keep you supplied so you don’t have to think about it too much.
If you need a little help, we’ve made it easy for you.

"The iPhone of air conditioners"
"Far nicer than any unit on the market right now"
When refrigerants leak into landfills, it’s pretty awful for the environment. Properly recycling your old AC unit is an easy way to prevent that.
