Eligibility: Whole-House Heat Pump Rebate (new system): $2,000 per ton up to $8,000 — up to $11,500 combined with weatherization. System must condition 100% of the home's living space and supply 90–120% of the heating load at design temperature; room-by-room Manual J required; attestation of disconnection of existing fossil fuel heating and cooling systems required. Weatherization is required in conjunction with installation (50% of cost up to $3,500 via an approved Abode home performance contractor; existing weatherization qualifies if home was built 2010 or later or recommendations from 2013 or later were completed). One whole-house rebate per RMLD account every 10 years; only one program option (rebate or loan) may be selected. Gas customers who receive Mass Save heat pump rebates are not eligible. Contractor must call RMLD at 781-942-6598 for a Utility Authorization Number and obtain a town electrical permit.
