Efficiency Vermont Heat Pump Rebate Guide: 2026 Amounts, Eligibility, and How to Claim

Last reviewed: 2026-07-31 (UTC)

Efficiency Vermont still offers live heat pump rebates in 2026, but the right number depends on more than one headline amount. For most air-source projects, the statewide base discount is $375-$475 for a ductless heat pump or $1,200-$2,200 for a centrally ducted heat pump. Your total can change again based on household income, utility territory, and whether the savings show up as an instant discount or a separate rebate application.

That is where quotes often get messy. A contractor may blend the statewide rebate, a local utility offer, and an old tax-credit assumption into one "after incentives" number even though each piece follows different rules. The safer approach is to separate each bucket before you sign.

Quick answer

Efficiency Vermont's current air-source base discounts start at $375-$475 for ductless systems and $1,200-$2,200 for centrally ducted systems. Separate live programs also cover integrated controls, air-to-water heat pumps, and ground-source systems, and some households or utility territories can add more savings on top.

The right number depends on system type, tonnage, household income, utility territory, and whether the program is an instant discount or a post-purchase rebate. If you are in Burlington Electric Department territory or another utility with its own offer, do not assume the statewide row is your final number.

2026 Efficiency Vermont heat pump rebate amounts to compare first

Which Efficiency Vermont rebate path fits your project?

The easiest way to misread this program is to compare your quote against the wrong rebate bucket.

Ductless mini-split

The ductless rebate page is the main answer for many homeowners searching "Efficiency Vermont heat pump rebate." It covers new ductless mini-split systems and pays a smaller statewide base discount than the centrally ducted path:

• $375 for systems at 2 tons or less
• $475 for systems above 2 tons

This path is often the cleanest fit when a home does not have strong existing ductwork or when the project is focused on specific rooms or zones.

Centrally ducted heat pump

The centrally ducted heat pump page covers systems tied to ductwork. The statewide base discount is larger:

• $1,200 at 2 tons or less
• $1,700 above 2 and below 4 tons
• $2,200 at 4 tons or more

Efficiency Vermont notes that these systems can be more complex, may require furnace compatibility checks, and often keep a fossil-fuel backup system in place. This is usually a hybrid heating decision, not just a straight equipment swap.

Integrated controls

The integrated controls rebate is a separate, project-specific offer worth up to $600. It only applies to new residential ductless mini-split installs in year-round single-family homes. The backup heating system must be oil, propane, or natural gas, the control must be on the qualifying list, and the customer contribution is $150.

Do not automatically add it to the ductless point-of-purchase discount. Efficiency Vermont's program page calls the controls rebate additional, but the current application form says it cannot be combined with another Efficiency Vermont offer, including point-of-purchase discounts. Because those official materials conflict, confirm the combination with Efficiency Vermont before you count both in a quote.

Air-to-water heat pump

The air-to-water heat pump rebate is a separate path for homes with water-based distribution, usually a radiant or boiler-connected setup. Efficiency Vermont lists it at $1,000 per ton up to 6 tons, with a $500 income bonus for eligible households.

If your quote is for a hydronic system, do not compare it against the ductless or centrally ducted air-source rows.

Ground-source heat pump

The ground-source heat pump rebate is the geothermal path. Efficiency Vermont says the rebate can reach up to $2,100 per ton, plus a $500 income bonus for eligible households.

If you receive electric service from Hyde Park Electric, you may not qualify for the full incentive amount. Efficiency Vermont says to call 888-921-5990 to confirm the incentives available for your project before applying.

Ground-source is the most paperwork-heavy of the live Efficiency Vermont heat-pump programs, so it deserves its own comparison rather than being treated like a simple version of the air-source rebate.

Who qualifies for the main Efficiency Vermont heat pump rebate?

Before income bonuses or local utility adders even matter, the core eligibility rules need to line up.

Across the official ductless, centrally ducted, air-to-water, and ground-source pages, the main repeated rules are:

• the equipment must be new,
• it must be installed in Vermont,
• and it must meet the program's product-specific qualifying equipment criteria at the time of purchase, often through a qualifying products list.

From there, the project-specific rules split out.

• Ductless: available through participating HVAC distributors, with the rebate tied to a system that includes an outdoor unit and one or more indoor units.
• Centrally ducted: eligibility depends on the equipment configuration, and Efficiency Vermont notes that some systems are judged on a combination of outdoor and indoor model numbers while some furnace-air-handler setups are judged by outdoor model number only.
• Integrated controls: only for new ductless installs in year-round single-family homes, installed by an Efficiency Excellence Network contractor in the integrated controls group.
• Air-to-water: requires a water-based distribution system and an Efficiency Excellence Network contractor in the air-to-water group.
• Ground-source: must be a new geothermal system, not a replacement of an existing geothermal system; customers who primarily heat with wood are not eligible. The program page says installation can use an Efficiency Excellence Network contractor in the ground-source or driller group, while the current rebate form says the installer must be enrolled in the ground-source heat pump group. Confirm the current form and contractor eligibility with Efficiency Vermont before installation. Systems can be up to 10 tons, and the equipment must either be ENERGY STAR certified or meet the listed AHRI performance criteria.

If your project depends on an income bonus, note one more constraint: the main income-bonus path on these heat-pump programs does not currently include rental property owners, and Burlington Electric Department customers are handled through separate local offers instead of the standard ductless or ducted income-bonus track.

How income bonuses and utility territory change your total savings

This is where many quotes get fuzzy.

The statewide base discount is only the first layer. After that, your total can change based on household income and utility service territory.

Income bonuses are not one flat Vermont number

Efficiency Vermont's income limit page uses county- and household-size-specific tables. The 2026 limits took effect July 1, 2026. Prior-year limits applied only to equipment purchased and installed before July 1, 2026, with the income-bonus application submitted by July 31, 2026.

For the main ductless and centrally ducted paths, the current Efficiency Vermont income section lists:

• Green Mountain Power low-income customers: $2,200 total
• VPPSA member-utility moderate- and low-income customers: up to $1,000
• All other moderate- and low-income customers: $200

The Green Mountain Power numbers describe two parts of one bonus, not two bonuses to stack. Efficiency Vermont's $2,200 figure is the total low-income bonus. The up to $2,000 shown in its partner table is the GMP-funded component of that total. Do not add $2,000 to $2,200.

The VPPSA amount is also conditional. The current VPPSA form combines an $800 VPPSA bonus, limited to one per customer, with $200 from Efficiency Vermont only when the customer installs more than one heat pump. A customer who received a heat pump through a previous VPPSA offer cannot receive the $800 component, and the form limits the offer to one bonus per household.

VPPSA's form also uses a program-specific income rule: it counts the gross income of family and non-family household members age 18 or older. Efficiency Vermont's general income page says household income includes all family and non-family members living in the household. Because those official definitions differ, confirm which household members apply to the VPPSA bonus before submitting.

That spread is one reason the same search can lead to very different real-world totals.

Utility territory can change the answer again

Current utility program pages and Efficiency Vermont partner tables also show local offers that do not fit neatly inside the statewide headline. The official sources do not always agree, so treat these figures as starting points to verify:

Treat these as territory-specific offers, not as automatic stackable savings for every project. Burlington Electric Department customers are the clearest example: BED's own page supports the combined maxima above, while Efficiency Vermont's current partner tables display different figures of up to $2,900 for ductless and up to $8,750 for ducted systems. Use BED's current page and confirm the address-specific total before signing; do not assume either summary table is final.

If your installer gives you one blended savings number, ask them to break it into three separate lines:

1. the statewide Efficiency Vermont base rebate,
2. any utility-specific local offer,
3. and any income-qualified bonus assumption.

That one question prevents a lot of quote confusion.

How to claim the rebate without missing the savings

The claim flow is not the same for every heat-pump path. That matters because some savings appear on the quote right away, while others require a separate Efficiency Vermont rebate application or form.

Ductless and centrally ducted: usually an instant discount

On the official ductless and centrally ducted pages, the statewide base offer is framed as an instant discount at time of purchase through the contractor or distributor flow.

That means the first thing to check is simple: does the base rebate already appear as a line item on the quote or invoice?

If it does not, ask the installer which participating distributor path they are using and whether they are assuming a later application instead. If the quote also assumes an income-qualified bonus, ask whether that bonus needs its own online or paper submission instead of happening automatically with the instant discount.

For a ductless or centrally ducted income bonus, submit the signed application with an invoice or copy of a dated sales receipt within 365 days of the product purchase date. A W-9 is required only when the rebate is paid to a business. The payee name must match the W-9, and a business payee that submitted a W-9 within the previous 12 months does not need to attach another copy.

Integrated controls, air-to-water, and ground-source: separate paperwork matters

The other live Efficiency Vermont heat-pump rebates work more like traditional applications. Their current forms say submissions are due within 365 days of the product purchase date, and the supporting invoices need more detail than a generic receipt.

• Integrated controls: submit the current form with invoice details for quantity, size, type, manufacturer, model or part number, purchase date, and vendor; include the required thermostat screenshot and a W-9 if the rebate is paid to a business.
• Air-to-water: submit the current HVAC rebate form or apply online with the same invoice details. The form conflicts with itself on W-9 paperwork: its submission steps say to include a W-9 "if applicable," while its payee block says a W-9 is required to receive the rebate. The separate income-bonus form requires a W-9 only when payment goes to a business. Confirm the W-9 requirement with Efficiency Vermont before submitting an air-to-water claim.
• Ground-source: submit the current rebate form with dated invoice details for quantity, size, type, manufacturer, and model or part number; include the required heating-load calculation, the GSHP start-up sheet, and a W-9 if the rebate is paid to a business.

The geothermal load calculation and start-up sheet are easy to miss, so ask your contractor for both before you submit the form.

The quote should show the rebate path clearly

Before you sign, ask the installer to identify:

• the exact rebate path they are using,
• the qualifying model numbers,
• whether the savings are instant or post-purchase,
• and which documents you will need to keep.

At minimum, keep your quote, invoice, model numbers, proof of purchase, and any submitted form copies in one folder. If the project is ground-source, keep the heating-load calculation and contractor start-up paperwork there too.

Can you stack the rebate with federal tax credits or other Vermont incentives?

This is the easiest place for a quote to overpromise.

Federal tax-credit wording needs to stay date-specific

The federal Energy Efficient Home Improvement Credit was available for qualifying heat pumps placed in service through Dec. 31, 2025. The IRS cutoff guidance confirms that heat pumps placed in service on or after Jan. 1, 2026 are not eligible.

For air-source heat pumps that qualified in 2025, ENERGY STAR says eligible models had to be recognized as ENERGY STAR Most Efficient, with a Cold Climate pathway for heating-dominated applications. The IRS also required specified 2025 property to come from a qualified manufacturer and the taxpayer to report the item's four-character Qualified Manufacturer Identification Number (QMID) on the return.

Two practical takeaways follow from that:

• do not assume a new 2026 installation still qualifies under the older federal heat-pump tax-credit rules,
• and do not assume every cold-climate or high-efficiency model would have qualified even before the cutoff.

If a quote for a 2026 project still shows federal savings, treat that as a separate assumption that needs its own verification.

Even older tax-credit math is not always a full simple stack

For the 25C credit, the IRS says you cannot claim a credit for the portion paid by a public-utility subsidy used to purchase or install qualifying property. Other rebates reduce the purchase price when they meet federal purchase-price-reduction tests; state energy-efficiency incentives generally do not reduce cost unless they qualify as rebates under federal tax law, and they may instead be taxable income.

If you are sorting out older quote math or a prior-year install, do not infer the tax treatment from a payment's "rebate" label alone. Compare the line items and confirm each payment's federal classification instead of relying on a bundled "after incentives" number.

HEAR and HOMES are not the same thing as the live Efficiency Vermont rebate

Vermont's broader HEAR and HOMES programs are separate from the current live Efficiency Vermont heat-pump rebate path.

The two federal programs are not at the same stage. A January 2026 Vermont Department of Public Service briefing says:

• HEAR is on pause while Vermont awaits further guidance from the U.S. Department of Energy.
• HOMES has moved further: Vermont's Joint Fiscal Office records show that the $29.3 million grant-acceptance request for low-income weatherization was approved on March 16, 2026. But the official grant packet describes program-design work performed before launch and says DOE approval is required before Vermont can disburse rebates or accept claims. Funding and implementation have advanced; these records do not prove that a consumer-facing HOMES rebate opened.

The state's program page also warns that rebates are not available before launch or retroactively. Do not count HEAR or HOMES savings in a current contractor quote unless Vermont publishes a later launch notice and confirms that your project qualifies.

So if a third-party roundup mixes HEAR, HOMES, and Efficiency Vermont into one simplified number, slow down and separate them before you budget around that total.

Quote-check checklist before you sign

Use this checklist before you treat any installer rebate number as final:

1. Match the project to the right rebate path. Confirm whether the quote is using ductless, centrally ducted, integrated controls, air-to-water, or ground-source rules.
2. Verify the exact model numbers. Make sure the equipment meets the current program-specific qualifying criteria at the time of purchase, including the qualifying products list where required.
3. Confirm utility territory in writing. Especially if you are in Burlington, GMP, Stowe, VEC, or a VPPSA municipality, make sure the quote reflects the correct local path.
4. Check the income-bonus assumption. Ask which household-income tier the quote is using and which application or form supports that number.
5. Separate instant discounts from later rebate applications. If the base rebate is supposed to appear on the quote, it should be visible as its own line item.
6. Separate rebates from tax-credit assumptions. Do not let a 2026 quote roll an old federal tax-credit estimate into the same savings bucket without supporting documentation.
7. Keep the paperwork organized. Save the quote, invoice, proof of purchase, model numbers, submitted forms, and any contractor start-up sheet.
