Energy efficient.

We're currently awaiting our official efficiency rating. But we estimate a 75-percent carbon reduction when the Gradient is used to both cool and heat and when the system is powered by low-carbon electricity. Our end goal is to achieve a 100-percent carbon reduction; we see our current model as a very important and very big first step toward that goal.

How it works

No system looks or works like Gradient.

HVAC systems are designed to move heat using a refrigerant. Because they work under high pressure, mini splits require professional, expensive installation. As for window ACs...well, that high pressure system is the reason they're designed as that big, bulky box that takes over your window.

Engineered to be svelte.

Our heat pump technology uses
coolant to distribute heat inside while keeping the high pressure refrigerant outside, resulting in less noise and less bulk.

Designed for the home.

By adding a secondary coolant loop at a much lower pressure, we’ve built a modular design that you can setup, install, and control yourself.

Commercial grade power.

Inside are professional-level components like variable speed fans, large heat exchangers, and reversible operations that keep you cool or warm all year round.
