Free solar and heat pumps cut energy bills by about 60% for some homes

When Lisa Theriault’s oil furnace died in the middle of a Maine winter two years ago, replacing it would have cost thousands she didn’t have. Instead, she enrolled in a state-backed program that installed a heat pump system in her Bangor home at no cost. Her heating bills dropped from roughly $300 a month to around $120. “I actually cried when I saw the first bill,” she told neighbors, according to local housing advocates familiar with the case.

Theriault’s experience reflects a broader pattern emerging from government electrification programs in cold-climate states. As of spring 2026, low-income households in Maine, New York, Massachusetts, and several other states can qualify for free or fully subsidized heat pumps, and in some cases, paired community solar subscriptions that offset electricity costs further. For homes that previously relied on oil, propane, or old electric resistance heating, the combined effect can cut energy bills by roughly 60 percent, according to efficiency benchmarks published by the U.S. Department of Energy’s ENERGY STAR program and early data from state program administrators.

That figure comes with important caveats. It represents a best-case scenario for homes swapping out the least efficient systems, not a guarantee for every participant. But the programs delivering these results are real, growing, and already reshaping how some of the country’s most energy-burdened families get through winter.

How the programs work

Maine’s effort is administered primarily through Efficiency Maine Trust, a quasi-state agency that runs low-income weatherization and electrification initiatives. Qualifying households, generally those at or below 80 percent of area median income, can receive free heat pump water heaters, ductless mini-split heat pumps for space heating, and in some cases insulation and electrical panel upgrades needed to support the new equipment. The program covers installation labor and equipment costs entirely for eligible applicants.

Heat pump water heaters work by pulling warmth from surrounding air rather than generating it from scratch, making them two to three times more efficient than conventional electric resistance units, according to the Department of Energy. Space-heating heat pumps operate on the same principle, extracting heat from outdoor air even in cold temperatures. Modern cold-climate models can function effectively in temperatures well below zero degrees Fahrenheit, a significant improvement over earlier generations that struggled in northern states.

The solar component typically comes through separate but complementary channels. Community solar programs, now available in more than 20 states, allow low-income subscribers to receive credits on their electric bills from a shared solar array without installing panels on their own roofs. When a household pairs a free heat pump with a community solar subscription that offsets a portion of its electricity costs, the compounding savings can be substantial. Several states, including New York, Illinois, and Colorado, have carved out specific low-income allocations within their community solar programs to ensure these benefits reach the households that need them most.

Where the 60 percent figure comes from

The approximate 60 percent reduction is grounded in engineering performance data rather than a single large-scale billing study. ENERGY STAR estimates that a heat pump water heater can save a household roughly $550 per year compared with a standard electric water heater. For space heating, the DOE notes that air-source heat pumps can reduce electricity use for heating by approximately 50 percent compared with electric resistance systems. Homes switching from delivered fuels like heating oil or propane, which are among the most expensive ways to heat a home in the Northeast, often see even larger percentage drops.

Efficiency Maine’s 2024 annual report noted that participants in its low-income heat pump pilot reported average heating cost reductions between 40 and 65 percent, depending on the fuel source being replaced and the condition of the home. Households replacing oil boilers in reasonably well-insulated homes landed at the higher end of that range. Those in drafty, poorly insulated structures saw smaller gains, underscoring the importance of weatherization as a companion measure.

Adding community solar to the equation can push savings further. A typical low-income community solar subscription in a state like New York or Maine provides a 10 to 20 percent discount on the subscriber’s electric bill. For a household that has already electrified its heating, that discount applies to a larger share of total energy spending, amplifying the dollar value of the credit. No published study has yet measured the precise combined effect of free heat pumps plus community solar across a large sample of low-income homes, but program administrators in multiple states say the stacked savings regularly approach or exceed 60 percent for participants who access both.

Who qualifies and how to apply

Eligibility varies by state, but most programs target households earning at or below 80 percent of area median income. In Maine, that translates to roughly $52,000 per year for a family of four in many counties, though the threshold shifts with local cost of living. Some programs also accept households that already participate in LIHEAP (the Low Income Home Energy Assistance Program), SNAP, or Medicaid as automatically income-eligible.

Applying typically starts with a home energy audit, conducted at no cost by a program-approved contractor. The audit identifies which upgrades will deliver the greatest savings and flags any preparatory work, such as insulation, air sealing, or electrical panel upgrades, that needs to happen before a heat pump can perform well. In most programs, that preparatory work is also covered, though funding caps and contractor backlogs can create wait times of several months.

Federal incentives layered on top of state programs have expanded access since the Inflation Reduction Act’s rebate provisions began rolling out. The IRA’s Home Electrification and Appliance Rebates (HEAR) program, administered through state energy offices, provides up to $8,000 toward a heat pump for qualifying low-income households. In states where HEAR funding stacks with existing state programs, the result is often full coverage of equipment and installation costs even for upgrades that exceed a single program’s cap.

Parallel efforts in the United Kingdom

The United States is not alone in subsidizing heat pump adoption for lower-income households. The United Kingdom’s Boiler Upgrade Scheme, which provides grants of up to £7,500 toward heat pump installation, has driven tens of thousands of installations since its launch. While the BUS is not income-tested in the same way as Maine’s program, the UK government has paired it with targeted support for fuel-poor households through its Warm Homes Plan and the Energy Company Obligation (ECO) scheme, which requires energy suppliers to fund efficiency improvements in low-income and vulnerable homes.

The UK’s energy regulator, Ofgem, tracks the impact of these programs through its oversight of the regulated energy price cap and supplier obligations. British households that have switched from gas boilers to heat pumps in well-insulated homes have reported heating cost reductions broadly consistent with the ranges seen in U.S. programs, though direct comparisons require caution. Energy prices, housing construction standards, and climate conditions differ significantly between the two countries. What the transatlantic parallel does confirm is that the underlying technology delivers consistent efficiency gains across varied markets when installations are done properly.

Limitations and open questions

The 60 percent figure, while grounded in credible benchmarks, is not universal. Several factors can shrink the savings considerably.

Homes with poor insulation lose heat faster than a heat pump can efficiently replace it, forcing the system to work harder and consume more electricity. In the coldest stretches of a Maine or Minnesota winter, even modern cold-climate heat pumps may need backup resistance heating to maintain comfortable temperatures, which spikes electricity use during the hours when it matters most. Households in regions with high electricity rates but low natural gas prices may find that switching from gas to electric heating does not produce dramatic savings, or in some cases increases costs.

Program capacity is another constraint. Efficiency Maine’s low-income initiatives serve thousands of households per year, but the state has tens of thousands of homes that would qualify. Contractor shortages, supply chain delays for equipment, and limited annual appropriations all cap how quickly programs can scale. Similar bottlenecks exist in other states. The gap between the number of families who could benefit and the number who actually receive installations remains wide.

Renters face particular barriers. Landlords, not tenants, typically control decisions about heating systems, and many landlords have little financial incentive to invest in upgrades when tenants pay the utility bills. Some states have begun designing programs that address this split-incentive problem, but solutions are still in early stages.

Finally, long-term maintenance costs are not yet well documented for low-income heat pump recipients. Heat pumps generally require less maintenance than combustion systems, but they are not maintenance-free. Filters need cleaning, refrigerant levels need checking, and outdoor units in snowy climates need clearance. Whether programs will provide ongoing support or whether maintenance costs will eventually erode savings for cash-strapped households is a question that will take years to answer fully.

What this means for families weighing the switch

For households that qualify, the practical calculus is straightforward: a free heat pump paired with community solar access represents one of the most effective tools available for reducing energy costs without any upfront investment. The 60 percent savings benchmark is realistic for homes replacing oil or propane heat in reasonably insulated structures, especially when a solar subscription offsets part of the electricity bill.

But families should go in with realistic expectations. Savings depend heavily on the starting point. A home already heated with relatively cheap natural gas will not see the same percentage drop as one burning $4-per-gallon heating oil. Insulation and air sealing matter as much as the heat pump itself. And wait times for program enrollment can stretch months, so applying early is worth the effort.

The broader trajectory is clear. State and federal investment in low-income electrification is expanding, not contracting. The IRA’s rebate programs are still ramping up in many states as of mid-2026, and several governors have proposed increasing state-level funding for heat pump programs in their latest budget cycles. For families on the fence, the window of available support is wider now than it has ever been.
