The U.S. Department of Energy quietly changed the rules on its $8.8 billion Home Energy Rebates program this spring, and the new guidance, effective May 29, 2026, bars homeowners from using the rebates to replace gas furnaces and other fossil-fuel equipment with electric heat pumps. Two states, South Dakota and Idaho, have declined to run the program at all.
What Actually Changed
The Home Energy Rebates program was created under the Inflation Reduction Act and splits into two pieces: the HOMES program ($4.3 billion, tied to whole-home energy savings) and the High-Efficiency Electric Home Rebate program, or HEEHR ($4.5 billion, aimed at specific electric upgrades). DOE’s own Program Notice 26-2, the guidance document governing HEEHR, spells out the change directly: it is “removing program allowances for upgrades for fuel-switching (i.e. replacement of non-electric appliances) and instead allowing rebates for upgrading HVAC and appliances only from existing electric equipment to more efficient electric equipment.”
In plain terms, a household with a gas furnace can no longer use a HEEHR rebate to help pay for a heat pump replacing it. Homes that already have electric heating and are upgrading to a more efficient electric system remain eligible, as does new construction. DOE did carve out one exception: households can still install a heat pump alongside an existing fossil-fuel system without losing eligibility, as long as they keep the old system rather than removing it, reversing the incentive structure that previously nudged people toward fully replacing gas heat.
The companion guidance for the HOMES program, Program Notice 26-1, made ENERGY STAR certification optional for participating states rather than mandatory, giving states more flexibility in which products qualify.
Why It Matters Now
The rebates were frozen for much of 2025 amid a broader review of IRA-funded programs, and this guidance is what restarted them, on narrower terms than originally designed. Advocacy groups have been blunt about the shift. Srinidhi Sampath Kumar, director of the Sierra Club’s Clean Heat campaign, said in the organization’s July 2026 statement that “Congress created these rebates to help households lower costs, reduce indoor air pollution, and improve home comfort and safety,” arguing the fuel-switching restriction cuts against the program’s original purpose.
Not every state is even offering the money. Idaho’s legislative budget committee voted to reject its federal allocation in March 2025, and South Dakota separately declined more than $70 million in related federal energy and environmental funding, according to reporting that tracked state-by-state rollout. That leaves homeowners in those two states without access to either rebate program regardless of what equipment they’re installing.
A Program That Was Already Uneven
Even before this guidance change, the rebates weren’t rolling out uniformly. A 50-state analysis published in March 2025 by the NC Clean Energy Technology Center found that of the states still participating at the time, only 11 states plus the District of Columbia were actively accepting rebate applications. The rest had received their federal allocations but hadn’t yet opened applications, largely because of a broader pause on disbursing IRA-appropriated funds. South Dakota’s opt-out predates that report; Idaho’s legislature voted to reject its allocation that same month, and both states remain outside the program entirely under the current guidance.
That means a homeowner’s actual experience with these rebates today depends heavily on three separate things layered on top of each other: whether their state opted in at all, whether that state has actually opened applications, and now, under the May 2026 notice, whether the upgrade they want done even qualifies.
What It Means for Your Renovation
If you were counting on a rebate to offset the cost of switching from gas to electric heat, budget as though that money isn’t there. Under the current guidance, it isn’t, unless your state’s program still has separate funding structured around the old rules before this notice took effect. If you’re already on electric heat and upgrading to a newer, more efficient unit, the rebate path is still open and arguably simpler to qualify for than before, since ENERGY STAR compliance is no longer a hard requirement in every state.
The most useful first call isn’t to a contractor, it’s to your state energy office, since implementation now varies more than it did when the federal rules were uniform. A rebate program that once had one national rulebook now effectively has 48 different versions of it, and which version applies to your renovation depends entirely on where you live and what’s currently in your basement.
