HOMES vs HEEHRA: Why You Can't Claim Both for the Same Heat Pump Upgrade and When the Performance-Based Rebate Pays More

Have you heard of the HOMES rebate? If you have spent any time researching federal heat pump money, you have almost certainly heard of HEEHRA — the point-of-sale program with the $8,000 heat pump line — and probably very little about its statutory twin.

Both programs came out of the same 2022 law, and both were funded at roughly the same scale: approximately $4.3 billion for Home Efficiency Rebates under Section 50121, and approximately $4.5 billion for Home Electrification and Appliance Rebates under Section 50122. What most homeowners miss is that a single project can draw on both programs while the statute forbids both from paying for the same upgrade.

That distinction carries far more weight in 2026 than it did in any prior year. With the 25C Energy Efficient Home Improvement Credit unavailable for property placed in service after December 31, 2025, these two state-run rebate programs now carry the bulk of the remaining federal dollars on a heat pump retrofit.

Two Programs, Two Different Theories Of What Gets Paid

HEEHRA pays for equipment. HOMES pays for results.

Under HEEHRA — formally the Home Electrification and Appliance Rebates program — a state administrator publishes a list of qualifying measures with a dollar cap on each one, and an enrolled contractor discounts the invoice at the point of sale. Eligibility turns on household income measured against area median income, and not at all on how much energy the finished project ends up saving.

HOMES, formally the Home Efficiency Rebates program, inverts that logic entirely. The payment is indexed to modeled or measured whole-home energy savings, which means the equipment list barely matters and the scope of work matters enormously.

Accordingly, two identical heat pumps installed in two identical houses can earn very different HOMES rebates depending on what envelope work rides along with them. That single difference drives nearly every decision below — and it is why the 25C versus HEEHRA decision tree that governed 2024 and 2025 projects no longer maps cleanly onto a 2026 installation.

What Each Program Actually Pays

The published caps are the fastest way to see where each program's ceiling sits. Keep in mind that state energy offices may adopt lower caps, narrower measure lists, or tighter contractor requirements than the federal maximums, so the table below describes the outer boundary rather than a quote.

All of the above assumes a single-family dwelling, since multifamily properties follow separate per-unit accounting under both statutes. Note that the HOMES tiers double for households below 80% of area median income, which is the one place where the two programs' income logic converges.

The other HEEHRA line items matter more than most coverage suggests: $4,000 for an electrical service panel, $2,500 for wiring, $1,600 for insulation, air sealing, and ventilation combined, and $840 each for an induction range or a heat pump clothes dryer. Those caps are what a homeowner is trading away when a measure gets routed to HOMES instead, and the panel line in particular is worth reading alongside our breakdown of heat pump panel capacity requirements.

The Statutory Bar, Read Literally

The prohibition lives in the electrification statute, which provides that a rebate under Section 50122 may not be combined with any other federal grant or rebate — including a Section 50121 rebate — for the same single upgrade. The operative words are single upgrade, not single project.

Department of Energy program guidance carries that reading down to the state level, requiring administrators to demonstrate that no individual measure was paid for twice. Projects may still contain measures funded from each program, which is precisely why state applications ask for a measure-by-measure funding source rather than one project-level election.

There is a second, quieter consequence that decides most real cases. When a measure is funded through HEEHRA, states generally require the HOMES savings claim to be calculated without that measure's savings, so whatever scope remains has to clear the savings threshold on its own.

What Counts As A Single Upgrade

The measure is the unit of accounting. The heat pump is one upgrade, the electrical panel that had to be replaced to land it is another, and the attic air sealing that shrank the design load is a third.

Where the line gets genuinely blurry is ancillary work bundled into a single equipment line on the invoice. If a contractor writes "heat pump system, including panel and circuit" as one number, a state administrator has no clean way to route the panel to HOMES and the outdoor unit to HEEHRA.

For that reason, the split is effectively decided on the estimate rather than after the install. Homeowners pursuing a split generally need line-item pricing before signing, since a bundled invoice is among the most common reasons a two-program application gets returned.

When The Performance-Based Rebate Pays More

HOMES wins in a narrower set of situations than the marketing around it implies, but those situations are common enough to be worth checking before a contract is signed. The scenarios where the performance-based rebate comes out ahead include but are not limited to:

• Household income above 150% AMI. HEEHRA is closed to these households entirely, which makes HOMES the only federal rebate still reachable on a 2026 installation. This is the single largest group affected by the loss of 25C, since the tax credit was the one federal incentive with no income ceiling at all.
• Envelope-heavy scopes. HEEHRA groups insulation, air sealing, and ventilation under one $1,600 cap, which binds hard on a $12,000 to $18,000 weatherization package. HOMES pays on the savings those measures produce rather than on the category, so a deep envelope retrofit can reach the $4,000 tier where HEEHRA would stop at $1,600.
• Measures outside the electrification list. Window replacement, duct replacement, and most non-electric efficiency work do not appear on the HEEHRA measure list at all. Any of that work is HOMES-eligible if it shows up in the model, which is often the deciding factor on older homes with failing distribution.
• Fuel switching away from delivered fuels. Because the modeled pathway is scored on site energy, a heat pump running at a seasonal COP near three does the same heating work on roughly a third of the site energy that combustion equipment consumes. Homes coming off propane or fuel oil tend to model into the upper tier more easily than homes coming off natural gas.
• No enrolled contractor in reach. HEEHRA runs through approved contractor networks, and rural markets in several states still have thin coverage. HOMES verification is handled by certified modelers and aggregators rather than the installing contractor, which changes who has to be enrolled.

All of these share one structural feature: the value of the project is concentrated in savings rather than in a single capped appliance. That is the pattern to look for, and it is the same pattern our rebate stacking guide uses to sort projects into program lanes.

When The Per-Appliance Caps Pay More

For income-qualified households doing a mostly equipment-driven project, HEEHRA usually wins outright. A household below 80% of area median income can have up to 100% of project cost covered against the caps, which no HOMES tier matches on a single-appliance job.

Timing reinforces that advantage. HEEHRA lands as a discount at the point of sale, while HOMES arrives after the work is finished and the model or measurement has been verified — a difference of months for families who cannot float a five-figure invoice.

There is also threshold risk to weigh. A HEEHRA reservation is priced off a published cap, whereas a HOMES rebate that misses 20% modeled savings pays nothing at all, and that binary outcome is the reason most single-measure retrofits stay in the electrification lane. Pairing a heat pump with a heat pump water heater under HEEHRA is frequently the cleanest version of this, since the two caps together reach $9,750 with no modeling requirement attached.

A Worked Split, Using Illustrative Costs

Consider a household between 80% and 150% of area median income running a $23,000 project: a $14,000 ducted heat pump, $6,000 of attic insulation and air sealing, and a $3,000 panel upgrade. The three available routes price out as follows, using published federal caps and illustrative project costs rather than a quote.

The split wins by roughly $400 — and only if the envelope work by itself models to at least 20% whole-home savings once the heat pump's savings are stripped out of the model. On a moderately tight house, envelope-only measures rarely clear that bar, which collapses the split back to the all-HEEHRA row.

What The Modeling Requirement Actually Costs

The HOMES modeled pathway is not a spreadsheet estimate. It requires a BPI-2400-compliant energy model calibrated against twelve months of utility billing history, produced by a certified professional and submitted to the state administrator before work begins.

That audit and modeling work is a genuine line item, typically running from a few hundred dollars to over a thousand depending on market and house complexity. On a project chasing a $2,000 tier, the modeling cost alone can eat a quarter of the rebate — which is the arithmetic that erases the $400 split advantage in the example above.

The measured pathway avoids the pre-project model but substitutes a metered baseline and a post-installation measurement period, usually administered through an aggregator rather than a homeowner. Payment rates per kilowatt-hour saved are set state by state, and the money arrives well after commissioning.

Be aware that a contractor who quotes a specific HOMES amount before the model has been run is quoting a hope. The same skepticism applies to load calculations: a rebate projection built on a rule-of-thumb sizing estimate rather than a room-by-room ACCA Manual J will drift, and our heat pump load calculator and guidance on cold-climate heat pump sizing both exist to catch that drift early.

How State Administration Changes The Answer

Neither program is administered federally. The Department of Energy awards funds to state energy offices, and each office writes its own measure list, contractor enrollment rules, income verification process, and launch schedule.

Several states opened their electrification program well before their efficiency program, and a handful still run only one of the two. Efficiency Maine, NYSERDA in New York, the California Energy Commission, and Focus on Energy in Wisconsin all administer their state's federal allocation under distinct rules, which means the split analysis above can produce different answers across a state line.

Utility programs sit in a separate layer entirely. The statutory bar reaches other federal grants and rebates, so ratepayer-funded incentives such as Mass Save, ConnectedSolutions, Energy Trust of Oregon, and Focus on Energy generally layer on top of either federal program, subject to each administrator's own stacking rules.

That layering is where the real 2026 money often hides. A household that loses 25C entirely may still recover a meaningful share of a project through a utility rebate plus one federal program, and our heat pump installation cost breakdown is the place to start on what remains out of pocket.

A Decision Rule By Project Phase

Where a household sits in the process narrows the question considerably. The useful framing is not which program is better in the abstract, but which doors are still open.

• Pre-purchase, nothing signed. The split question is fully live, and line-item pricing plus a standalone envelope savings scenario will settle it. This is also the only phase where switching contractors to reach an enrolled HEEHRA network costs nothing.
• Mid-application, HEEHRA reservation issued. The heat pump is now committed, so any HOMES claim has to stand on the remaining measures alone against the 20% modeled or 15% measured floor. Most households at this stage find the remaining scope too thin and stay in a single program.
• Already installed. HEEHRA operates at the point of sale and HOMES requires a pre-project model or metered baseline, so both federal doors are generally closed. Attention shifts to non-federal utility and state programs, which frequently accept post-installation applications within a defined window.

Overall, the honest summary is that most 2026 projects belong entirely in one program, and the split is a narrower tactic than its popularity suggests. The households it genuinely serves are those with envelope work large enough to model on its own and equipment work large enough to consume the HEEHRA caps.

For the underlying eligibility mechanics, state-level income tiers, and current program status, our HEEHRA program guide and the running federal tax credit status page track what has changed since the 25C sunset — including why the old HEEHRA and 25C stacking play no longer applies to work placed in service this year.
