HVAC Tax Credits and Rebates in 2026: What Homeowners Can Actually Claim

Most homeowners leave money on the table when replacing HVAC equipment — not because the programs are hard to use, but because no one explains them clearly. Federal tax credits, state rebate programs, and utility incentives all exist simultaneously and often stack. A homeowner replacing a gas furnace and air conditioner with a high-efficiency heat pump could realistically reduce total out-of-pocket costs by $3,000–$10,000 or more, depending on their income, state, and equipment choice.

Federal Tax Credit: IRA Section 25C Energy Efficient Home Improvement Credit

The Inflation Reduction Act (Public Law 117-169, signed August 2022) expanded the existing Section 25C credit significantly starting in tax year 2023 and extending through tax year 2032. If you replace qualifying HVAC equipment in 2026, you can claim this credit on your 2026 federal income tax return (filed in early 2027).

How it works

The credit equals 30% of the cost of qualifying equipment and installation, subject to per-category annual caps. It is a non-refundable credit — it reduces your federal tax liability dollar-for-dollar, but it cannot create a refund if your credit exceeds what you owe. Unused credit does not carry forward to future years.

The credit resets every tax year. You can claim it again in a future year for a different qualifying improvement.

What HVAC equipment qualifies and for how much

The $2,000 heat pump credit is in addition to the $1,200 general cap. A homeowner who installs a qualifying heat pump and separately installs energy-efficient windows (another 25C category) can claim up to $3,200 in a single year.

ENERGY STAR "highest efficiency tier" — what it means in practice

For air conditioners, the IRS references the ENERGY STAR Most Efficient designation, which changes year to year as technology advances. In 2026, the practical minimums for the credit are approximately:

• Split-system central AC: SEER2 ≥ 16 in the South and Southwest; approximately SEER2 ≥ 15.2 in the North — but verify with your contractor and IRS guidance, as these can shift
• Heat pump (air-source): SEER2 ≥ 16, EER2 ≥ 12, HSPF2 ≥ 9 (approximate — confirm against current ENERGY STAR criteria)

Not every heat pump on the market qualifies. When getting quotes, ask contractors to confirm the specific model number qualifies for the 25C credit and have them pull the ENERGY STAR certification documentation.

How to claim the credit

1. Purchase and install qualifying equipment in 2026
2. Keep the itemized purchase receipt, the manufacturer's certification statement (required by the IRS), and the contractor's installation invoice
3. Complete IRS Form 5695 (Residential Energy Credits) and attach it to your federal return
4. The credit reduces your federal tax liability line by line

You do not need to itemize deductions to claim this credit — it works even if you take the standard deduction.

Who can claim it

• The home must be your primary residence in the United States
• New construction does not qualify — equipment must be installed in an existing home
• Renters do not qualify for the equipment credit (landlords may qualify under separate commercial provisions)
• There is no income cap for the 25C credit

State Rebate Programs: HEEHRA (High-Efficiency Electric Home Rebates)

IRA Section 50121 established the Home Efficiency Rebates program, commonly called HEEHRA (High-Efficiency Electric Home Rebate Act). Unlike the 25C tax credit, these are point-of-sale rebates — money off the price you pay the contractor, not a tax credit claimed later.

What HEEHRA offers for HVAC

Income eligibility

HEEHRA is income-targeted, unlike the 25C credit:

Area Median Income varies by location. A household income of $70,000 might be below 80% AMI in a rural area and above 80% AMI in a high-cost city. Use the DOE's income lookup tool at homes.repp.us or your state's program portal to confirm.

Program status by state

The federal government funded these programs, but each state administers its own version. Rollout has been uneven. As of July 2026:

• Active programs in most states: The majority of states have launched HEEHRA programs, though application processes, contractor requirements, and rebate amounts vary
• Some states have waiting lists or temporary pauses due to high demand
• Contractor enrollment required: In most state programs, you must use a contractor who is registered with the state's HEEHRA program — not all contractors have enrolled

Critical step: Before scheduling a replacement, check your state energy office website or the DOE's rebate finder at energysaver.gov to confirm your state's program is open, find enrolled contractors, and understand the application process.

Stacking HEEHRA with the 25C credit

Yes, you can claim both. A homeowner who installs a qualifying heat pump and qualifies for HEEHRA can receive:

• Up to $8,000 off the purchase price (HEEHRA rebate, applied at point of sale)
• Up to $2,000 back on their federal taxes (25C credit, claimed on tax return)

These are separate programs and do not reduce each other's value.

Utility Rebates: The Layer Most Homeowners Miss

On top of federal credits and state rebate programs, most major electric utilities offer their own incentives for efficient HVAC equipment — particularly heat pumps. These rebates do not require income eligibility and do not affect federal or state programs.

Typical utility rebate amounts (2026)

How to find your utility's rebates

1. Look up your electric utility's website and search "rebates" or "energy efficiency incentives"
2. Check the DSIRE database (dsireusa.org) — a national database of state and utility incentives maintained by NC State University
3. Ask your HVAC contractor — many contractors are familiar with local utility programs and will apply the rebate on your behalf at point of sale (instant rebate) or walk you through the mail-in process

Example: How the programs stack

A homeowner in Georgia replacing a 15-year-old gas furnace and AC with a qualifying air-source heat pump at a total installed cost of $12,000:

This is a realistic best-case for a qualifying low-to-moderate-income household. Results vary based on income, equipment model, utility territory, and state program availability.

Manufacturer Rebates: Smaller but Real

Most major HVAC brands run seasonal rebate promotions, typically $100–$500 off qualifying equipment. These are handled through your contractor:

• Carrier, Lennox, Trane, American Standard, Goodman, Rheem, and others all offer these programs
• They typically require equipment purchase within a promotional window (often spring for AC, fall for furnaces)
• Submit through the manufacturer's rebate portal with a copy of your invoice — your contractor can usually help

Manufacturer rebates stack with all other programs above.

What to do right now: a practical checklist

1. Confirm your income bracket relative to your area's AMI to know if HEEHRA applies to you (energysaver.gov income lookup)
2. Check your state energy office website for HEEHRA program status and contractor enrollment
3. Find utility rebates at dsireusa.org — search your state and filter by "residential"
4. Ask contractors when getting quotes:
   • Does this specific model qualify for the IRS 25C credit? Can you provide the manufacturer's certification statement?
   • Are you enrolled in my state's HEEHRA rebate program?
   • Are there current manufacturer rebates on this equipment?
5. Get the paperwork from your contractor at installation: itemized invoice, model number, efficiency ratings, and manufacturer's certification — you will need these for Form 5695
6. File Form 5695 with your 2026 federal return

How credits and rebates affect your financing decision

If you're financing an HVAC replacement, the tax credit and rebates change the math significantly:

• A $2,000 tax credit is equivalent to reducing the financed amount by $2,000 at zero cost — apply it to your principal payment when the credit arrives
• HEEHRA rebates hit at the point of sale, directly reducing how much you need to borrow
• Utility rebates typically arrive 6–12 weeks post-installation as a check — plan to apply that toward any balance
