What Mass Save® Means by Air Source Heat Pumps
Mass Save® uses the term air source heat pump for equipment that moves heat between outdoor air and indoor living space. In summer, the system removes heat from the home like an air conditioner. In winter, a cold-climate heat pump extracts heat from outdoor air and delivers it indoors. This category can include ductless mini split systems, ducted heat pump systems, and hybrid layouts that use both ducted and ductless indoor units. The program is connected to participating Massachusetts utilities, not to a single manufacturer or installer. Participation generally requires an eligible Massachusetts utility account, qualifying equipment, proper installation, and the documentation requested by the program. Incentives may be organized by project type, whole-home status, equipment performance, or other program criteria. The exact amounts and rules can change, so Prodigy verifies current program details instead of quoting fixed figures. For homeowners, the important first question is not just whether a heat pump qualifies. It is whether the selected heat pump will heat and cool the actual rooms comfortably during Massachusetts weather.
