  • “As soon as the Windmill came of out of the box I thought, bye bye industrial age, hello sleek and chic.”

  • “A minimalist design that fades into the background of your living space”

We’ve all been there.

The AC that sounded like it was drumming. The one that made your curtain dance all night. The one that left a puddle every time it rained. Not ideal. It’s time for something quieter, cleaner, and way better looking.

Designed in NYC
