Get a Free QuoteTaunton, Raynham, Berkley, and part of Lakeville can't use Mass Save — but TMLP Saves runs an income-tiered program: $1,250/ton standard (up to $5,000), or $2,250/ton if you income-qualify(up to $9,000). It's ARPA-grant-funded and first-come, so timing matters.
Verified against tmlp.com and the program administrator June 10, 2026. Federal 25C tax credit EXPIRED Dec 31, 2025.
TMLP Saves pays $1,250 per ton for a standard cold-climate air-source heat pump (up to $5,000). Income-qualified households get $2,250 per ton — an extra $1,000/ton — capped at $9,000. Ground-source whole-home systems pay $5,000 standard or $9,000 income-qualified. TMLP also covers 50% of weatherization up to $3,000. The 2026 cycle is funded by a one-time $1M ARPA grant, so it is first-come. TMLP customers in Taunton, Raynham, Berkley, and part of Lakeville cannot use Mass Save — this is their program instead.
Mass Save is funded by an energy-efficiency surcharge on investor-owned utility bills (Eversource, National Grid, Unitil). TMLP is a municipal lighting plant — its customers don't pay that surcharge, so they are not eligiblefor Mass Save heat pump rebates. Generic “MA heat pump rebate” pages routinely miss this for Taunton-area homeowners.
TMLP runs TMLP Saves, designed with Abode and funded for 2026 by a one-time $1M ARPA grant. Its distinguishing feature is an explicit income-tiered structure: $1,250/ton standard or $2,250/ton if you income-qualify. If you heat with natural gas, your gas utility may still have Mass Save gas-side offers.

Federal 25C Tax Credit: EXPIRED. Section 25C ended December 31, 2025. There is $0 in federal heat pump tax credits in 2026. TMLP Saves rebates, weatherization, and the 0% loan are the live incentives.
Unlike Mass Save, which is bankrolled by an ongoing ratepayer surcharge, the 2026 TMLP Saves cycle runs on a one-time $1 million ARPA state grant. That is a fixed pool: when it is committed, the cycle closes. The 2026 cycle opened January 2, 2026. Applying early is genuine urgency, not a sales pitch.

What this means for you. Because the pool is finite, the income-qualified $9,000 tier is most secure when claimed early in the cycle. Confirm remaining funds with TMLP before you commit to an installation date.
Even though TMLP customers can't access Mass Save rebates, TMLP uses the Mass Save Heat Pump Qualified Product List (HPQPL)as its approved-equipment list. The system must be sized to 90–120% of the home heating load and cover 100% of the conditioned space — a genuine whole-home design.

Refrigerant note. R-410A systems are ineligible if installed on or after January 1, 2026, under the A2L transition to R-454B / R-32. Any HPQPL equipment your installer specs for a 2026 install should already be A2L-compliant.
TMLP covers 50% of air sealing and insulation up to $3,000, plus 50% of barrier mitigation (knob-and-tube, asbestos, and similar) up to $2,000 — all within a $10,000-per-year program funding cap. It is a precondition, but with clear exemptions.
