Liberty Utilities (MA) & Heat Pump Rebates in the Fall River Area
Liberty is your gas company — National Grid files your heat pump rebate
Liberty Utilities supplies natural gas to Fall River and a cluster of southeastern Massachusetts towns, and it's a bona-fide Mass Save sponsor — but only for gas. A heat pump runs on electricity, and Mass Save routes each rebate to the sponsor for the equipment's fuel. So your heat pump rebate files through your electric sponsor, which across Liberty's entire Massachusetts gas footprint is National Grid.
Fall River is the textbook example: National Grid electric + Liberty Utilities gas. The up-to-$8,500 heat pump rebate is a National Grid filing; Liberty handles the gas-equipment and weatherization side. Confirm your electric sponsor any time with the Mass Save Sponsors directory.
Liberty Utilities gas towns in Massachusetts
Liberty serves gas in Fall River, Bellingham, Blackstone, North Attleborough, Plainville, Somerset, Swansea, Westport, and Wrentham. Electricity in all of these is National Grid — so in every one of them, National Grid is the utility that processes your heat pump rebate while Liberty covers gas and weatherization.

See the full Mass Save rebates hubVerified 2026-09-19
Whole-Home Heat Pump Rebate
$2,650 /ton
Capped at $8,500 per home
The installed heat pump must be the sole source of heating and cooling for the spaces served. Equipment must be ENERGY STAR Cold Climate certified and listed on the Mass Save Heat Pump Qualified Products List (HPQPL). A Manual J load calculation is needed to qualify for the sizing bonus and is industry-standard practice on Mass Save projects.
Partial-Home / Supplemental Heat Pump Rebate
$1,125 /ton
Capped at $8,500 per home
Heat pump installed alongside an existing primary heating system. Equipment must be on the HPQPL. Lower per-ton rebate reflects supplemental rather than sole-source use.
Basic Heat Pump Rebate
$250 /ton
Capped at $2,500 per home
New for 2026. Applies to replacing an existing heat pump with a new qualified HPQPL-listed heat pump, or conditioning a previously unconditioned space.
$500 Right-Sized Equipment Bonus Partial-home
Partial-home installs only. Equipment must be sized to meet 90–120% of the total heating load at the outdoor design temperature, documented via an ACCA Manual J load calculation submitted with the rebate application.
$500 Weatherization Bonus Partial-home
Partial-home installs only. Requires a Mass Save Home Energy Assessment plus installation of the recommended weatherization (typically air sealing and insulation) within one year prior to or up to six months after the heat pump installation.
Financing
Mass Save HEAT Loan
0% APR up to $25,000
- Below 135% of State Median Income: 7 years (84 months)
- 135%–300% of State Median Income: 5 years (60 months)
- Over 300% of State Median Income: 3 years (36 months)
Subject to bank underwriting through participating Massachusetts lenders. Covers equipment + installation costs for qualifying high-efficiency upgrades (heat pumps, ductless mini-splits, insulation, water heaters, and batteries enrolled in ConnectedSolutions). A Home Energy Assessment is mandatory before financing a whole-home heat pump. Households below approximately 81% SMI typically route to Mass Save's no-cost / enhanced-rebate programs rather than the HEAT Loan.
No federal heat pump tax credit applies in 2026.
- Section 25C Energy Efficient Home Improvement Credit (heat pump portion) (30% of cost up to $2,000 annually for qualifying heat pump installations (inflation reduction act expansion)) ended for property placed in service after 2025-12-31 under the One Big Beautiful Bill Act (P.L. 119-21).
- Section 25D Residential Clean Energy Credit (geothermal portion) (30% of installed cost for ground-source (geothermal) heat pumps, with no dollar cap) ended for property placed in service after 2025-12-31 under the One Big Beautiful Bill Act (P.L. 119-21).
Status as of 2026-09-19: neither 25C nor 25D has been reinstated or replaced by Congress. Pending bills (e.g. H.R. 616) have not advanced. Pre-2026 §25D installs may carry forward unused credits.
Rebate amounts and eligibility verified 2026-09-19 against primary program documentation. We re-check before any publish.

Fall River and the South Coast: a strong conversion case
Fall River and the surrounding South Coast have dense older housing — triple-deckers, mill-era multifamily, and pre-1940 single-families — much of it on oil or gas heat without central cooling. That makes the region a natural fit for ductless mini-split heat pumps: they add cooling, cut heating cost, and claim the up-to-$8,500 rebate. Owners of two- and three-family buildings should read the multifamily rebate guide, since each dwelling unit can claim its own rebate. For oil-heated homes, start with the oil-to-heat-pump playbook.
How the filing works
- Schedule a free Mass Save Home Energy Assessment (National Grid administers it for your address).
- Choose a Mass Save HPIN-enrolled installer; confirm enrollment before signing.
- Your installer runs an ACCA Manual J and specs an HPQPL-listed, R-32 or R-454B cold-climate model.
- After install, the installer files through the Mass Save contractor portal; National Grid processes the rebate.
- The rebate check typically arrives 6–12 weeks after filing.
Liberty Utilities MA heat pump FAQ
- Does Liberty Utilities offer a heat pump rebate in Massachusetts?
- Not directly. Liberty Utilities is a gas-only Mass Save sponsor, and heat pumps run on electricity, so your heat pump rebate files through your ELECTRIC sponsor instead. Across Liberty's Massachusetts gas territory — Fall River, North Attleborough, and nearby towns — the electric utility is National Grid, so the up-to-$8,500 heat pump rebate is a National Grid Mass Save filing. Same statewide amount; it just doesn't come from Liberty.
- I have Liberty gas in Fall River — who files my heat pump rebate?
- National Grid, your electric sponsor. Fall River is a classic split-sponsor city: National Grid Electric plus Liberty Utilities gas. Your air-source heat pump rebate (up to $8,500 whole-home) is a National Grid filing, while gas furnace, gas water heater, and weatherization rebates would go through Liberty. Heat pump rebates always follow the electric sponsor because heat pumps are electric equipment.
- Which Massachusetts towns does Liberty Utilities serve gas?
- Liberty Utilities supplies natural gas in Fall River plus Bellingham, Blackstone, North Attleborough, Plainville, Somerset, Swansea, Westport, and Wrentham in southeastern Massachusetts. Electric service in these towns is National Grid, which is who processes your heat pump rebate.
- How much is the heat pump rebate for a Liberty Utilities customer?
- The statewide Mass Save standard: up to $8,500 whole-home at $2650/ton, or up to $8,500 partial-home at $1125/ton with $500 sizing and weatherization bonuses, plus the 0% HEAT Loan up to $25,000. Filed through National Grid; equipment must be on the Mass Save HPQPL with an HPIN-enrolled installer.
- What does Liberty Utilities cover as a Mass Save sponsor?
- The gas side: rebates for high-efficiency gas heating equipment and water heaters, and Home Energy Assessments plus weatherization (air sealing, insulation) for gas-heated homes. If you're keeping gas heat, that's a Liberty filing. If you're switching to a heat pump, the rebate is National Grid — though Liberty's weatherization can still unlock the $500 weatherization bonus on your heat pump project.
- Are the federal heat pump tax credits still available in this area?
- No. The federal §25C ($2,000 heat pump) and §25D (30% geothermal) credits both expired December 31, 2025 under the One Big Beautiful Bill Act. The IRA-funded HEAR rebate (up to $8,000 for households at or below 80% AMI) survives via the Mass Save income-eligible pathway.
