HVAC Solutions for All Occasions
Fast-track carbon emissions reduction in your home with a Gradient window heat pump.
They rattle, we purr
Gradient’s modular design places the power and noise outside your window, leaving you with heating and cooling that keeps the calm inside.
Comfort is in your control
Our commercial grade heat pump technology is more efficient than traditional window AC units, which saves on energy consumption and monthly bills.
Energy efficient
We're currently awaiting our official efficiency rating. But we estimate a greenhouse gas emissions reduction of up to 95% when the Gradient is used to cool and heat, depending on your source of electricity. That’s like choosing to walk instead of drive up to 15 miles daily – just by switching to Gradient. Our end goal is to achieve a 100% carbon reduction; we see our current model as a very important and very big first step toward that goal.

Original window heat pump magic
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 water to distribute heat inside while keeping the high pressure refrigerant outside, resulting in less noise and less bulk.
-
Designed for you in mind.
By adding a secondary coolant loop at a much lower pressure, we’ve built a modular design that you can set up, 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.
