• Equipment displacing natural gas eligible only for commercial or industrial metered customers receiving natural gas service from a Sponsor of Mass Save, including those in municipal electric territories.
• Equipment displacing oil, propane, or electric resistance eligible only for commercial or industrial metered customers receiving electric service from a Sponsor of Mass Save.
• Equipment must be listed on the Mass Save Heat Pump Qualified Product List (QPL).
• Equipment must be used for heating to supplement or replace existing oil, propane, natural gas, or electric-resistance systems.
  • If existing fossil fuel heating equipment will remain in place, customer must either install an integrated control from the Mass Save QPL (MassSave.com/cihpqpl) or must certify that an existing building control system is capable of operating both the heat pump and existing heating equipment in parallel, subject to the stated switchover temperature. Documentation of control sequence may be required.
• Equipment that has already received a rebate from a Sponsor of Mass Save or is being installed in a new construction or major renovation project is not eligible for a rebate.

Contact your Sponsor before installation if:

• The proposed project is more than 150 tons for Cape Light Compact, Eversource, or National Grid customers; larger systems will be reviewed on a case-by-case basis. For Berkshire Gas, Liberty, or Unitil customers, all projects require preapproval.
• The proposed project is for a new building being constructed or a major renovation (visit www.MassSave.com/cincmr).
  • Projects looking to pursue an incentive specifically for a heat pump, please visit the Path 3: High Performance Buildings webpage for more information.
• The proposed project is for a multifamily building, as rebate eligibility depends on the metering of the facility.
• The heat pumps that are being installed will be using a hydronic or water loop internal to the building (i.e., not a ground loop) as a heat source/sink.
• You or your contractor has questions about project eligibility.
• The proposed project is replacing existing heat pump equipment.
