Cool the World

We’re on a mission to build a healthier, more comfortable world for all those who inhabit it — without compromising the environment.

In the past fifty years, we’ve made a lot of progress. We’ve built electric cars, cell phones and the Internet — and yet, somehow, HVAC technology has barely changed. We still burn oil and natural gas in our furnaces and rely on ugly window ACs to cool our homes.

With Gradient, progress has arrived. Our heat pump technology is the first of its kind. It’s beautiful, powerful, efficient and planet-friendly — made for people who are unwilling to compromise on their values or aesthetics.

"The Gradient unit resembles a bench with two thick supports that you hang over a window sill. The clever design means the unit doesn't obstruct the view out the window and places the noisier components on the outside."
