You can still claim furnace replacement tax credits in 2026, but you’ll need to act fast since the Section 25C Energy Efficient Home Improvement Credit expires December 31, 2025. This federal credit offers up to $600 for qualifying furnaces with 97%+ AFUE ratings that meet ENERGY STAR certification requirements. You’ll also find state and utility rebates ranging from $300 to $1,500 or more. Understanding the specific requirements and deadlines will help you maximize these savings opportunities.
Key Takeaways
- Federal Section 25C tax credit expires December 31, 2025, so no federal furnace credits available in 2026.
- High-efficiency furnaces with 97%+ AFUE qualify for $600 federal tax credit through 2025 only.
- State and utility rebate programs may continue in 2026, offering $300-$1,500 for qualifying furnace replacements.

What Is the 25C Energy Efficient Home Improvement Credit?
When you’re considering a furnace replacement, the Section 25C Energy Efficient Home Improvement Credit can substantially reduce your upfront costs. This federal energy tax credit allows you to claim up to 30% of qualified home improvements, with a maximum credit of $1,200 annually.
The Energy Efficient Home Improvement Credit covers HVAC systems including central air conditioners, gas furnaces, and heat pumps that meet specific efficiency standards. For heat pump installations, you can qualify for an additional $2,000 maximum credit for high-efficiency HVAC systems installed in your primary residence.
These tax credits and rebates apply to energy-efficient home upgrades under the Residential Energy Property Expenditures program. Equipment must typically meet ENERGY STAR certification requirements and be fully operational by December 31, 2025, when the credit expires.
Don’t wait until the last minute—incomplete installations by the deadline could result in missing out on these valuable incentives for your energy-efficient upgrades.
Federal Tax Credit Changes Coming in 2026
Several important federal tax credits for energy-efficient home improvements will sunset after 2025, potentially affecting your furnace replacement decisions.
The Section 25C Energy Efficient Home Improvement Tax Credit expires December 31, 2025. This federal tax credit currently provides up to $1,200 annually for qualifying improvements to heating and cooling systems, plus an additional $2,000 for high-efficiency heat pumps and other premium HVAC equipment.
The Section 25D Residential Clean Energy Credit, offering 30% credits for geothermal heat pump installations, also ends after 2025. Additionally, the Section 45L New Energy Efficient Home Credit expires for homes purchased after June 30, 2026, while the Section 179D Commercial Building Energy-Efficiency Deduction ends for construction projects beginning after that date.
These changes stem from efforts to scale back Inflation Reduction Act provisions. If you’re considering upgrading your HVAC systems, acting before these deadlines guarantees you’ll maximize available incentives for qualifying energy-efficient equipment.
Qualifying Furnace Systems and Equipment Requirements
Not every furnace qualifies for federal tax credits—you’ll need to meet specific efficiency and certification requirements to claim these savings.
Under the Inflation Reduction Act (IRA), qualifying systems must meet stringent standards for energy efficiency improvements. Your new HVAC Products must achieve an AFUE of 97% or higher to earn the federal tax credit starting in 2025.
Here’s what you need to verify before purchasing:
- AHRI Certification: Your furnace must appear in the AHRI Directory of Certified Product Performance with the “Potential Eligibility for IRA Tax Credit*” designation
- Documentation Requirements: Keep your AHRI certificate and installation records as proof when filing your tax return
- Installation Deadline: Complete your furnace replacement by December 31, 2025, when the program expires
The 25C tax credit provides up to $600 for qualifying equipment and installation costs, making high-efficiency natural gas furnaces more affordable for homeowners pursuing energy efficiency improvements.
Maximum Credit Amounts for Furnace Replacements
While the federal tax credit provides substantial savings, understanding the exact amounts you can claim helps you budget effectively for your furnace replacement project. The 25C tax credit offers up to $600 for qualifying energy-efficient furnace installations, making it a valuable home improvement incentive for residential properties.
To secure the maximum $600 tax savings, your new furnace must achieve an Annual Fuel Utilization Efficiency (AFUE) rating of at least 97%. This high-efficiency requirement guarantees you’re investing in equipment that delivers long-term energy savings while qualifying for federal support.
State and Utility Rebate Programs Available
Beyond federal tax credits, dozens of state governments and utility companies provide additional rebate programs that can substantially reduce your furnace replacement costs. These incentives typically range from $300 to $1,500 or more, making high-efficiency furnace upgrades more affordable.
Most rebate programs require specific qualifications to guarantee maximum energy savings:
- Efficiency Standards: Your new furnace must meet ENERGY STAR certification or maintain a minimum AFUE rating of 95% to qualify for rebates.
- Eligibility Factors: Some programs consider your homeowner’s income level or the type of fuel used by your existing furnace when determining rebate amounts.
- Application Process: Many utility companies offer an instant discount applied directly at purchase, reducing your upfront investment immediately.
You’ll find the best rebate opportunities by contacting your local utility company or state energy office. They’ll provide current program details and help you identify which furnace replacement incentives you’re eligible to receive.
Steps to Claim Your Furnace Tax Credits and Rebates
Once you’ve selected your qualifying high-efficiency furnace, claiming your tax credits and rebates requires careful attention to timing and documentation. First, verify your furnace replacement meets ENERGY STAR certification and the Consortium for Energy Efficiency (CEE) highest efficiency tier requirements under the Inflation Reduction Act (IRA).
During installation, obtain your AHRI Certificate from the contractor—this document proves your energy efficient furnace qualifies for the federal tax credit of up to $600. Keep all receipts, warranties, and installation documentation for your tax filing.
Complete your furnace replacement before December 31, 2025, as the tax credit expires afterward. File the appropriate IRS forms with your federal return to claim the credit. Simultaneously, apply for any available state rebates through your utility company or state energy office. Many state rebates have separate application processes and deadlines, so don’t delay submitting required paperwork to maximize your total savings.
