With new regulations placing emissions limits on individual buildings -- and household gas bills expected to rise sharply -- more building owners are turning to electric heating and cooling solutions. Gradient provides one such solution, a window heat pump that can be installed in 15 minutes. Unlike with mini-split heat pumps, there's no need to hire an electrician or professional HVAC technician to install a Gradient heat pump. In addition, switching to Gradient doesn't require drilling or permitting, which means you don't have to worry about disturbing mold, asbestos, or lead in older buildings.

Gradient has contracted with the New York City Housing Authority to install 10,000 window heat pumps in NYCHA housing and has partnered with Brooklyn-based BlocPower, a climate technology leader, to electrify the heating and cooling systems of multifamily homes across the country. It was named one of TIME's best inventions of 2022, a Fast Company 2022 World Changing Idea, and a winner of the House Beautiful Live Better Awards 2022.
