Effective January 1, 2023, the federal government will be issuing new standards for heat pump products which will cause manufacturers to replace HSPF and SEER efficiency ratings with HSPF2 and SEER2. At that time, the Sponsors of Mass Save will update efficiency requirements for residentially-sized air source heat pump equipment (rated below 65,000 Btu/h of cooling capacity) to align with the new federal standards (i.e., ENERGY STAR 6.1 Cold Climate Certification standard). To ease the transition to the new standards, the Sponsors will consider any models that meet either the current criteria or the new criteria as eligible for installation through December 31, 2023.
