A Quick Start Guide to Federal Tax Credits for Heat Pump Upgrades

What Are the Federal Tax Credits for Heat Pump Upgrades?

Federal tax credits for heat pump upgrades were available to U.S. homeowners for qualifying installations completed by December 31, 2025. If you installed a qualifying heat pump in 2025, here is what you need to know at a glance:

If you had a qualifying heat pump placed in service before the end of 2025, you can still claim the credit when you file your 2025 federal tax return — the deadline to file is April 15, 2026, or October 15, 2026 with an extension.

For Metro Atlanta homeowners, this is a significant opportunity. Heating and cooling account for the largest share of energy use in most homes. Upgrading to an energy-efficient heat pump not only lowers your monthly utility bills — it could also put real money back in your pocket at tax time, as long as the system met the required efficiency standards and was fully operational before the 2025 deadline.

In this guide, we walk you through everything you need to know: which systems qualify, what efficiency ratings are required, how the credit caps work, and exactly how to file. Whether you are still sorting out your 2025 taxes or planning ahead for future upgrades, the information below will help you make smart decisions.

Understanding Federal Tax Credits for Heat Pump Upgrades (Section 25C & 25D)

When looking at federal tax credits for heat pump upgrades, it is vital to distinguish between the two primary tax provisions established by the federal government: Section 25C and Section 25D. Both offer a robust 30% credit for qualifying expenses, but they target different technologies and operate under very different limits.

Section 25C: The Energy Efficient Home Improvement Credit

Section 25C is the workhorse for most residential energy upgrades. It covers standard air-source heat pumps and heat pump water heaters. Under this section, you can claim a tax credit equal to 30% of the total cost of purchase and professional installation, up to a strict annual cap of $2,000.

Because this is an annual limit rather than a lifetime cap, homeowners who planned ahead were able to maximize their tax savings by staging their home improvements. For example, you could claim the maximum credit for a heat pump water heater in one tax year, and then claim the credit for a central air-source heat pump the following year.

Section 25D: The Residential Clean Energy Credit

Section 25D focuses on renewable energy systems, which includes geothermal (ground-source) heat pumps. Unlike Section 25C, Section 25D offers a 30% credit with no annual maximum dollar cap and no lifetime limit. Geothermal systems harness the stable temperatures underground to provide highly efficient heating and cooling. While these systems require a more intensive installation process, the 30% uncapped credit provides substantial financial relief at tax time.

To understand the key differences between these two tax credits, review the comparison table below:

Understanding the Advantages of Investing in Heat Pump System can help you appreciate why the federal government heavily incentivizes these systems. They deliver exceptional climate control while drastically reducing carbon emissions and energy consumption.

Qualifying Equipment, Efficiency Standards, and Eligibility

Not every heat pump on the market qualifies for a tax credit. To protect consumers and ensure true energy savings, the IRS mandates strict performance criteria.

To qualify under Section 25C, electric or natural gas heat pumps and heat pump water heaters must meet or exceed the highest non-advanced efficiency tier established by the Consortium for Energy Efficiency (CEE) that was in effect at the start of the calendar year in which the system was placed in service.

Efficiency Ratings for Federal Tax Credits for Heat Pump Upgrades

The technical criteria for federal tax credits for heat pump upgrades are based on standardized efficiency metrics: SEER2 (Seasonal Energy Efficiency Ratio 2), EER2 (Energy Efficiency Ratio 2), and HSPF2 (Heating Seasonal Performance Factor 2). These ratings measure cooling and heating efficiency under specific testing conditions.

The exact rating requirements depend on the equipment configuration:

• Split Ducted Systems: To qualify, split ducted heat pumps must generally meet a SEER2 rating of 15.2 or higher, along with corresponding EER2 and HSPF2 standards. The entire system—including both the indoor coil and the outdoor unit—must be replaced and certified as a matched system.
• Packaged Systems: These single-cabinet systems must also meet a minimum SEER2 of 15.2 to qualify.
• Non-Ducted (Ductless Mini-Split) Systems: Because mini-splits do not suffer from duct-related energy loss, they are held to a higher standard. Non-ducted heat pumps must meet a SEER2 rating of 16.0 or higher to qualify for the tax credit.

If you are considering a zoning solution or do not have existing ductwork, exploring the Benefits of a Mini Split Heat Pump is highly recommended. Our Ductless Heat Pump Installation Complete Guide provides a deep dive into how these versatile systems are configured and installed to meet federal standards.

Home Types Eligible for Federal Tax Credits for Heat Pump Upgrades

Eligibility for these tax credits is also determined by how you use the property:

• Primary Residence Rules: For Section 25C (air-source heat pumps and water heaters), the equipment must be installed in an existing home located in the United States that serves as your principal residence. New construction homes do not qualify for Section 25C credits.
• Second Homes: Under Section 25C, you cannot claim credits for a second home, vacation home, or property that you rent out. However, Section 25D (geothermal heat pumps) does allow you to claim the credit for a second home, provided you use it as a residence during the year and do not rent it out full-time.
• Renters vs. Homeowners: Renters can technically claim the Section 25C credit for qualifying equipment (like a window-mounted heat pump or a tenant-purchased system) that they pay for themselves, although structural building envelope upgrades (like insulation or windows) require homeownership.
• Business Use Limitations: If you use your home partially for business (such as a dedicated home office), your eligibility depends on the percentage of business use. If your home is used less than 20% for business, you can claim the full tax credit. If business use exceeds 20%, you must prorate the credit based on the share of residential use.

The 2025 Placed-in-Service Deadline and 2026 Filing Rules

Timing is everything when dealing with federal tax incentives. The Energy Efficient Home Improvement Credit (Section 25C) and the Residential Clean Energy Credit (Section 25D) were subject to critical legislative changes.

Under Public Law 119-21 (also known as the One Big Beautiful Bill Act), the termination of these residential tax credits was accelerated. As a result, both Section 25C and Section 25D expired for residential property placed in service after December 31, 2025.

This means that to qualify for the federal tax credit, your heat pump upgrade must have been fully installed and operational on or before December 31, 2025.

Now that we are in June 2026, homeowners who completed their installations in 2025 are actively filing their tax returns. If you are filing on the standard timeline or have secured a tax filing extension through October 15, 2026, you can still claim your 2025 installation.

Ensure your documentation clearly reflects a "placed-in-service" date in 2025. If you had a system installed in Atlanta or Alpharetta during that timeframe, our historical guides can help you verify compliance details:

How to Claim the Credit and Combine with Georgia Rebates

Claiming your tax credit requires careful filing. You must use IRS Form 5695, Residential Energy Credits, and submit it alongside your federal income tax return.

Step-by-Step Filing Instructions

1. Gather Your Records: You will need your itemized contractor invoice showing the equipment model numbers, labor costs, and the exact date the system was placed in service.
2. Obtain the Manufacturer’s Certification: Keep a copy of the Manufacturer’s Certification Statement. This document proves the model meets the required SEER2, EER2, and HSPF2 ratings.
3. Locate QMID or PIN Numbers: For 2025 installations, the IRS requires you to report the Qualified Manufacturer Identification Number (QMID) or Product Identification Number (PIN) directly on Form 5695. This code confirms the unit was made by a registered, qualified manufacturer.
4. Complete Form 5695: Use Part II of the form for Section 25C (air-source heat pumps and water heaters) or Part I for Section 25D (geothermal systems). Calculate 30% of your total qualifying expenses, apply the annual limits ($2,000 for air-source systems), and transfer the final credit amount to Schedule 3 of your Form 1040.

Combining Credits with State and Utility Rebates

Many Georgia homeowners want to know if they can combine ("stack") federal tax credits with local utility rebates or state programs. The short answer is yes—but the order of operations matters for your tax calculation.

Under IRS rules, utility connection subsidies or upfront point-of-sale rebates must be subtracted from your total project cost before you calculate your 30% tax credit. For example, if your heat pump installation was eligible for an instant utility rebate, you must subtract that rebate amount from the invoice total, and then calculate your 30% federal credit based on the remaining balance.

Additionally, the High-Efficiency Electric Home Rebate Act (HEEHRA) provides income-qualified households with point-of-sale rebates of up to $8,000 for heat pump heating and cooling systems. If you utilize a HEEHRA rebate, the rebate amount reduces your out-of-pocket cost, and your 30% tax credit is calculated on the net amount you paid.

Frequently Asked Questions about Heat Pump Tax Credits

Can I claim the tax credit for a heat pump installed in 2026?

No. Following the passage of Public Law 119-21, federal tax credits under Section 25C and Section 25D expired for new residential equipment placed in service after December 31, 2025.

However, if you are installing a heat pump in 2026, you can still take advantage of other local and state-level incentives. Georgia utility companies (such as Georgia Power) and local electric cooperatives continue to offer valuable rebates for upgrading to high-efficiency heat pumps. Additionally, state-administered HEEHRA programs may still offer point-of-sale rebates for qualifying low-to-moderate-income households.

Is there an income limit for the federal tax credit?

There are no income limits to qualify for the Section 25C or Section 25D federal tax credits. Homeowners at any income level can claim them.

However, because these are nonrefundable tax credits, you must have federal tax liability to benefit from them. If your tax liability for the year is zero, a nonrefundable credit cannot trigger a refund check, and under Section 25C, any unused credit cannot be carried forward to future tax years.

This is a key difference from HEEHRA rebates, which are point-of-sale discounts specifically restricted by income. HEEHRA offers up to 100% funding (up to $8,000) for households earning below 80% of their Area Median Income (AMI), and up to 50% funding for households earning between 80% and 150% of their AMI.

Are installation and labor costs covered by the credit?

Yes, professional installation and labor costs are fully eligible for both Section 25C (air-source heat pumps) and Section 25D (geothermal systems). This includes necessary electrical upgrades—such as installing a new panelboard or branch circuits—provided they are completed specifically to support the new heat pump.

It is important to note that this is different from other home improvements. For instance, building envelope components—such as insulation, exterior doors, and energy-efficient windows—have a separate combined annual limit of $1,200. Furthermore, the labor costs to install insulation, doors, or windows do not qualify for the tax credit; only the material costs are eligible.

Fortunately, heat pumps and heat pump water heaters are exempt from this restriction, allowing you to include 100% of the professional labor and installation charges in your 30% credit calculation, up to the $2,000 annual limit.

Conclusion

Navigating the rules for federal tax credits for heat pump upgrades can seem complex, but the financial rewards are well worth the effort. For systems installed in 2025, claiming your credit on Form 5695 is a smart way to offset your investment in reliable, year-round home comfort.
