HVAC Solutions for All Occasions

Fast-track carbon emissions reduction by electrifying buildings like multi-family homes, hotels, schools, and more.

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.
