Welcome to the Cold Climate Heat Pump Decision Tool. The goal of this tool is to help guide contractors and installers through the decision-making process for heat pump (HP) sizing and selection, with a focus on retrofit applications in cold climates. Users will provide information below. The tool will provide HP size, configuration, and further installation guidance. Completion of the tool may take between 15 and 30 minutes.
Please start by providing information about the home, existing heating and cooling equipment, and the project objective below.
Consider improving the building envelope prior to installing new equipment. Adding insulation, weatherizing, and air-sealing may lower heating and cooling loads and improve comfort. See the Retrofit Decision Tool for more details.
