HVAC rebate and incentive questions

IRS pages read September 5, 2026

The federal credits

The federal credits are where most of the wrong information is, because the position changed recently and a very large amount of published material was written while the credits existed.

Is there a federal tax credit for a heat pump in 2026?

No: The IRS page for §25C states the credit “is allowed for qualifying property placed in service on or after Jan. 1, 2023, and before December 31, 2025”.

It was terminated by Public Law 119-21. For property placed in service in 2026 the federal credit is $0.

The date that governs is when the equipment was installed and ready for use — not when it was ordered or paid for — so a system bought in December 2025 and commissioned in January 2026 falls on the wrong side of the line.

What about the 30% credit for geothermal?

Also gone: Geothermal sat under §25D, the Residential Clean Energy Credit, whose IRS page states the credit “is not available for any property placed in service after December 31, 2025”.

This is the more expensive loss of the two: §25D was 30% of project cost with no dollar cap, so on a geothermal quote the difference between a proposal showing the credit and reality can run to five figures.

My system went in during 2025. Can I still claim anything?

Possibly, on the 2025 return: §25C covered property placed in service before December 31, 2025, with IRS annual limits of “$2,000 per year for qualified heat pumps, water heaters, biomass stoves or biomass boilers” and “$1,200 for energy efficient property costs and certain energy efficient home improvements”, and $150 for a home energy audit.

The item had to come from a qualified manufacturer, with its Qualified Manufacturer Identification Number on the return; get it from the manufacturer or contractor. The credit was nonrefundable: “The credit is nonrefundable, so you can’t get back more on the credit than you owe in taxes.” Ask a tax professional.

How do I tell whether an article about rebates is out of date?

Check the federal line first: If a page published in 2026 still lists a $2,000 federal heat pump credit or a 30% federal geothermal credit as currently available, it has not been re-verified since 2025, and nothing else on it should be trusted either.

It is a reliable freshness test for the whole page, and it takes about ten seconds.

The same test works on a contractor’s proposal: a “federal tax credit” line in the savings column of a 2026 quote is quoting a closed program.

Both quotations above were read from irs.gov on September 5, 2026; the §25C page was itself last reviewed by the IRS on 2026-04-28. Tax law changes and it changed here recently — confirm the current position at irs.gov and with a tax professional before letting any credit, or its absence, decide a purchase.

What qualifies, and who

Eligibility has three separate tests — the equipment, the installer and the household — and a claim fails if any one of them fails. Most people only check the first.

Does a new gas furnace qualify for anything?

Not federally, and it depends locally: There is no federal credit for a furnace placed in service in 2026.

Locally the answer splits by who is paying: gas utilities frequently run high-efficiency furnace rebates because a more efficient furnace serves their own efficiency obligation, while state electrification programs generally do not, because their statutory purpose is to move homes off combustion.

If you have separate gas and electric utilities, that is two separate program searches and neither will mention the other.

Does my equipment have to be ENERGY STAR certified?

Often, but the binding test is usually the certified rating rather than the label. Programs qualify equipment on a measured performance number — SEER2, HSPF2, or a CEE tier — and that rating belongs to a matched combination, not to a box.

An outdoor unit on its own does not carry a certified SEER2. A quote that names only a condenser model number has not yet told you what the system is rated at.

Look the combination up yourself in the AHRI Directory at ahridirectory.org, using the outdoor unit, the indoor coil and the air handler or furnace together, and keep the AHRI Reference Number.

It is the single piece of documentation most rebate applications ask for and most homeowners do not have.

Does it matter which contractor I use?

For many programs, decisively: They pay only when the installer is on their own enrolled or participating list.

A contractor being licensed, insured and excellent does not make them enrolled — enrollment is a separate commercial choice, and some good firms decline it because of the paperwork burden.

Ask each bidder, by name of program, before you sign, and get the answer in writing.

This is discovered after the work is done more often than any other eligibility failure, and there is no remedy at that point.

What does “income-qualified” actually mean?

That eligibility is set against area median income rather than against the equipment. The federally funded state electrification rebates use this structure, which means two identical installations at neighboring addresses can qualify for different amounts, or for nothing.

Area median income is a county or metropolitan figure, so the threshold is local and the same household income can be inside it in one county and outside it in the next.

Your State Energy Office publishes the figure that applies to you; no national page can.

Do I need a permit for the rebate?

Usually yes, and the reason is worth knowing: Many programs ask for evidence of a permitted, code-compliant installation, and some ask for the final inspection sign-off before they pay.

That is a deliberate design: it prevents the program funding work that was never inspected.

It also means a contractor offering to skip the permit is offering to forfeit your rebate, whatever else is wrong with the suggestion.

Permit requirements are municipal and vary between neighboring towns, so the authority to ask is your local building department.

Where the money is actually lost

When to apply, and in what order

Rebate programs are not a list you work through at leisure. Several close permanently at a specific moment in your project, and that moment is usually earlier than people expect.

Do I have to apply before the installation?

For a large share of programs, yes — and it is the most final failure there is. Look for the words “pre-approval”, “prior approval” or “application must be submitted before installation” on the program’s own page.

Submitting is not the same as being approved: some programs issue a reservation or authorization number that must exist before the equipment arrives, and that number has to appear on the final claim.

If your contractor wants to install next week and the program takes three weeks to approve, that is a real conflict to resolve now rather than discover afterwards.

Why was my rebate claim denied?

Almost always for one of four reasons, none of them about the amount. The application was filed after installation on a program requiring pre-approval; the installer was not enrolled in the program.

The equipment combination did not carry the required certified rating; or the documentation was incomplete — most often a missing AHRI Reference Number or an invoice that did not separate labor from equipment.

A fifth, less obvious one: the funding window had already closed. These are budget-limited programs on annual cycles, and a popular category can exhaust its budget months before the program year ends.

In what order should I do all this?

Bidders first, utility second, state third, then apply, then install. Ask each bidder which programs they expect the job to qualify for and whether they are enrolled on each.

Then open your own utility’s rebate page — the utility whose account number is on your bill, not a comparison site. Then contact your State Energy Office.

Only then file the applications that require pre-approval, and wait for approval before scheduling installation. The order is chosen so the program with the tightest deadline is the one you reach first.

The full sequence, with the failure mode at each step, is on the rebate program router.

How long after installation can I still claim?

Post-install windows of 60 or 90 days are common, and the clock usually starts at the in-service or invoice date rather than the contract date. Keep the itemized invoice, AHRI Reference Number, every model number, installation date, contractor’s license number and any permit together from day one.

Chasing them later from a contractor who has moved on is where valid claims die.

My contractor says they will handle the rebate. Is that fine?

It can be, and it needs one check: Some rebates are midstream — paid to the distributor or contractor and passed on as a lower price.

If that is what is happening, the discount must appear as a visible line item on your invoice.

Without that line you have no evidence the discount reached you, and the program now records that rebate as spent on your address, so you cannot claim it yourself.

Ask for it itemized before you pay the balance, which is the only moment you have leverage.

What a rebate is actually worth

The honest answers here are smaller than the headlines, and they come from federal figures rather than from program marketing.

Why you will not find dollar amounts here

Because we cannot source them in a way we could keep honest: The broadest public index of US incentives is DSIRE, maintained by the NC Clean Energy Technology Center.

Checked September 5, 2026, its public web app is free to browse but its data API refuses unauthenticated requests with a license notice, and it publishes no open bulk download.

We hold no license, so we link to DSIRE on its own site rather than republishing what it holds.

And an amount decays: budgets close mid-year, tiers are revised, a utility can change its own terms on a Tuesday, and a static table gives no signal when it has gone wrong.

That is why so many currently published rebate tables still show a federal credit that ended in 2025.

How much money is actually in the federal rebate programs?

$8.03 billion was allocated to the 50 states and DC, which is $65.01 per household. HyreHVAC calculation from DOE’s own allocation table and EIA’s household count.

Set against a program whose headline maximum is $14,000, that tells you the shape of the thing: it is a targeted subsidy that will be exhausted by a relatively small number of large claims, not a benefit most households will receive.

It also varies — from $305.87 per household in Wyoming to $42.25 in New York, a 7.2 to 1 spread created by a small-state floor in the allocation formula.

The full workings and all 51 jurisdictions are on the rebate statistics page.

Can I stack a utility rebate and a state rebate on the same job?

Sometimes, and the rule is always in the program terms rather than the marketing. Programs routinely forbid stacking with a named other program, or cap the combined incentive at a share of project cost.

Read the stacking clause in both sets of terms before applying to either, because the first application can lock you out of the better one.

Where stacking is allowed, note that a rebate reducing what you paid generally reduces the cost you may count toward any tax credit — that is a tax question for a tax professional, and it is a real one for state credits even now that the federal ones are closed.

Should I delay replacing my system until a rebate arrives?

Recommendation: not on a system that has failed, and rarely on one that is failing. Uptake has always been small: Treasury reported more than 250,000 families claiming a heat pump credit in tax year 2023, about one household in 494 on our arithmetic.

No national page can tell you whether or when a program will open in your state.

Waiting has a real cost: emergency replacement in the middle of a heating or cooling season removes your ability to get competing bids, which is worth more than most rebates.

The defensible version of waiting is a short, bounded delay on a working system while you get a definite answer from your State Energy Office.

Context for the scale: 13.9% of US homes already heat with a heat pump and 50.8% heat with natural gas (EIA RECS 2020). The conversion pool the electrification rebates were written against is tens of millions of homes; the money allocated is not sized to it, and was never intended to be.

Renters, landlords and the awkward cases

The ordinary rules assume an owner-occupier replacing their own equipment. A large share of American housing is not that.

I rent. Can I apply for anything?

Ask your State Energy Office first, because the answer is state-specific. Two tests usually apply at once. Utility rebates generally go to the account holder, often the tenant. State and federally funded programs are generally tied to the owner, because the measure attaches to the building.

So the person who benefits from a lower bill and the person who may authorize the work are frequently different people, and neither program is designed around that.

Where renter and multifamily provisions exist, they live in the state program rules. Whether you may authorize work on a landlord’s equipment is a matter of the lease and state law, not of the rebate program.

I let the property. Do the same rules apply to me?

The pre-approval and enrolled-contractor rules bind you exactly as they would an owner-occupier. The complication is the utility account: if the tenant is the account holder, a utility rebate may have to be paid into an account that is not yours, and the program will not resolve that for you.

Settle it with the tenant in writing before applying. Some state programs carry specific multifamily or rental provisions with different documentation requirements — again, the State Energy Office is the authority.

My system failed in the middle of winter. Is any of this realistic?

Mostly not, and it is better to know that than to chase it: Pre-approval windows and enrolled-contractor requirements do not bend for an emergency, and a household without heat cannot wait three weeks for a reservation number.

The realistic move is to ask the two or three contractors who can actually come out whether they are enrolled anywhere, and to file any post-install claim afterwards.

Keep every document from the job regardless — the itemized invoice, model numbers, AHRI Reference Number and permit — because a post-install program may still pay, and reconstructing that paperwork later is the hard part.

Nothing on this page is legal, tax or financial advice. HVAC installation involves refrigerant, gas piping, flues and electrical connections; refrigerant handling is federally regulated under EPA Section 608, and gas and electrical work are licensed trades.

This page is about paperwork and deadlines around work performed by a qualified contractor, never a description of work to do yourself.
