The cost of installing an air-source heat pump (ASHP), also called mini-split, in your home will vary significantly based on the specifics of your project, including the kind of equipment you select, the layout of your home, and whether any electrical upgrades are required. As a result, MassCEC cannot say what a “good” price is for your air-source heat pump. However, we can help you see what others are paying for air-source heat pumps projects around the Commonwealth.
The cost data is presented based on the heating capacity of the equipment (measured at a 5° Fahrenheit outdoor temperature) to make comparing equipment of differently-sized easier. This is listed as Cost ($) per Ton, which is equivalent to Cost ($) per 12,000 British Thermal Units per hour (BTU/hr).
Air source heat pump systems include single-head, multi-head, and central ASHP systems. A single-head ASHP system has one outdoor compressor unit connected to a single indoor conditioning unit. Central ASHP systems condition air at a central location and distribute it throughout the building utilizing a distribution system. Multi-head ASHP systems have one outdoor compressor unit connected to multiple indoor conditioning units.
The data below comes from residential heat pump projects that received a rebate from MassCEC between November 2014 and March 2019. While the rebate program has ended, the data will remain available on this page to provide a reference for cost distribution in Massachusetts.
