The short answer
Heat pumps are efficient. They are also, in most gas-heated homes, more expensive to install than a conventional replacement system. Those two facts pull in opposite directions, and the gap between them is usually smaller than people expect.
That is why incentives carry so much weight. A few thousand dollars of rebate money can flip a ten-year comparison that efficiency alone would not. Remove it, and the same project can look like a poor use of capital.
The complication is that incentive money is not distributed evenly. Federal rebate funds were handed to individual states to design and administer, so availability, size and eligibility now differ enormously from one state to the next — and increasingly from one utility to the next.
Why the economics are so finely balanced
A heat pump does something fundamentally different from a furnace or a baseboard heater. It does not create most of its heat from electricity. It uses electricity to move heat from outdoor air into the house.
That distinction is measured as coefficient of performance. A resistance heater converts one kilowatt-hour of electricity into roughly one kilowatt-hour of heat. A heat pump running at a coefficient of performance of 3.0 delivers about three — roughly one-third of the electricity for the same heat. Against electric resistance heating, that advantage is large and the case is usually straightforward.
Against natural gas it is a closer contest, because the comparison is no longer efficiency against efficiency. It is the price of electricity against the price of gas. The U.S. Energy Information Administration expects the average residential electricity price to reach 18.29 cents per kilowatt-hour in 2026, up 5.7% from 2025, and 18.70 cents in 2027 (Short-Term Energy Outlook). Where gas is cheap and electricity is not, the fuel-switching math gets harder regardless of how efficient the equipment is.
Our own scenario work points the same direction. When a heat pump installs for close to the price of a furnace and air conditioner, it competes well. When it carries a meaningful price premium, the annual operating savings often take longer to repay that premium than most owners keep the equipment. The result varies by climate and by local rates, which is why we publish the assumptions rather than a single verdict — see the case studies and the heat pump versus conventional system comparison.
What an incentive actually does to the numbers
The clearest way to see the effect is to hold everything constant and change only the rebate. Below is a ten-year comparison for a gas-heated home, first with no incentive and then with an $8,000 rebate applied.
| Ten-year cost component | Heat pump | Gas baseline |
|---|---|---|
| Equipment and installation | $13,200 | $12,400 |
| Heating energy | $35,890 | $28,961 |
| Cooling electricity | $8,280 | $8,715 |
| Maintenance | $3,000 | $3,300 |
| Incentive | $0 | $0 |
| Ten-year total, no incentive | $60,370 | $53,376 |
| Incentive applied | −$8,000 | $0 |
| Ten-year total, with incentive | $52,370 | $53,376 |
Scroll the table sideways to see the gas baseline column.
Without the rebate, the heat pump costs about $6,994 more over ten years. With it, the heat pump comes out roughly $1,006 ahead. Nothing about the equipment changed. One line item did.
Ten-year total cost, same house, same equipment
Two cautions about reading a table like this. The margin is thin, so small changes in local rates can reverse the ranking. And an incentive is a one-time reduction in capital cost — it does not change what the system costs to run.
Why this money exists at all
Heat-pump incentives are a policy instrument, not a manufacturer discount. States and utilities are trying to shift building heating from fuel combustion to electricity, and that shift only works if households actually replace equipment on a similar timeline to the grid investments being made alongside it.
Buying down the upfront cost is the most direct lever available, which is why incentive levels have been set aggressively. It also explains their instability. Money tied to policy goals and annual budgets can be reserved, paused or redesigned faster than most homeowners plan a renovation.
Worth keeping in perspective: heat pumps already account for a large share of new equipment sales — about 47% of residential cooling equipment sold in 2025, and more units than gas furnaces every year since 2021 (RMI market tracking). The installed base moves far more slowly. As of the most recent national housing survey, 16.13 million of 123.53 million U.S. homes used a heat pump as their main heating equipment, roughly 13% (EIA Residential Energy Consumption Survey).
The two federal rebate tracks, in plain English
Alongside utility programs, most statewide rebates trace back to two federal funding streams created by the Inflation Reduction Act. States run them under their own program names, so the labels you encounter locally will differ.
Track one pays for equipment, for lower-income households. The Home Electrification and Appliance Rebates program covers households earning under 150% of area median income. It is designed to arrive as a discount on the invoice rather than a check afterward. A qualifying heat pump for space heating and cooling is worth up to $8,000, within a combined household cap of $14,000 that can also cover a heat-pump water heater, an electrical panel upgrade, wiring, and insulation and air sealing. Households under 80% of area median income can have up to 100% of costs covered; those between 80% and 150% can have up to 50% covered (program terms).
Track two pays for measured results, at any income. The Home Efficiency Rebates program rewards whole-house energy reduction rather than a specific appliance. A modeled reduction of at least 20% earns the lesser of $2,000 or half of project cost; at least 35% earns the lesser of $4,000 or half of project cost. Low-income households earn double, up to $4,000 and $8,000 respectively, and up to 80% of project cost (program terms).
The practical difference matters. The first track is a straightforward equipment rebate if you qualify on income. The second usually requires pairing the heat pump with insulation and air sealing, plus modeling or measurement to prove the savings — more work, and a less certain amount.
States are permitted to offer a narrower set of technologies and household types than federal rules allow, and many do (state discretion). Do not assume the federal maximums are what your state actually pays.
Availability depends on where you live
Because each state built its own application system on its own timeline, the same household can face completely different offers across a state line.
Maine runs a mature, openly published rebate schedule — $3,000 per outdoor unit for low-income households up to a $9,000 lifetime cap, $2,000 for moderate income, and $1,000 at any income level (Efficiency Maine). New York layers federal rebate money into its existing income-qualified program, which combines a no-cost energy assessment with funding toward heat pumps, water heaters and electrical upgrades (NYSERDA EmPower+).
California shows the other outcome. Demand for single-family rebate money outran the budget, and statewide single-family funds are now fully reserved with a waitlist rather than open applications (program status). The program was not cancelled. It simply ran out, which for a homeowner pricing a project today amounts to the same thing.
What to confirm before you count on an incentive
- Is it open right now? Published rebate amounts often outlive the funding behind them. Confirm the program is accepting new applications, not just that it exists.
- Do you have to reserve it first? Many programs require approval before installation begins. Installing first can disqualify an otherwise eligible project.
- Does the specific equipment qualify? Rebates usually attach to certified models, minimum efficiency ratings and particular replacement scenarios — not to heat pumps generally.
- Can it be combined? Utility, state and federal offers sometimes stack and sometimes exclude one another. Get the answer in writing before it is priced into your budget.
- Who receives the money? Point-of-sale discounts reduce what you finance. Reimbursements do not, which affects the project even when the total is identical.
Where to go next
An incentive changes what you pay for equipment. It does not change how efficient that equipment is, how much energy your house uses, or what electricity and gas cost where you live. Those are separate questions, and a project can qualify for substantial rebates while still being a weak investment — or the reverse.
Start with your serving utility, since utility programs are frequently the most reliably open source of money and the least affected by state budget cycles. Then check your state's program status.
