Pumped up on heat pumps: Maine leads the nation on installations
Air-source heat pumps are gaining traction in Maine. In 2019, Gov. Janet Mills set a goal to install 100,000 units — in homes, businesses and public buildings — by 2025, along with enhanced rebates through Efficiency Maine and a low-income heat pump program at MaineHousing. The target was exceeded two years early with 104,000 installations.
