What Counts as a Central Heat Pump for Mass Save Rebates?
A central heat pump is a ducted air-source heat pump system designed to heat and cool multiple rooms through connected ductwork. In a typical Massachusetts installation, the system includes an outdoor heat pump unit, an indoor air handler, refrigerant piping, controls, return air pathways and supply ducts. The system may use existing ducts, modified ducts or newly installed ductwork, depending on the home. For Mass Save Central Heat Pump Rebates, the key issue is not simply whether the equipment can heat and cool. The project must align with program rules for eligible equipment, installation scope, utility participation and documentation. Mass Save generally separates heat pump incentives by project type, such as whole-home displacement, partial displacement or supplemental applications. Those categories affect how the program reviews the application. A ducted central heat pump can be a strong fit for homes that already have central air conditioning, homes with accessible attic or basement duct routes and homes where owners want fewer indoor wall units.
