Tax Credit on New Furnace Guide – If you’re a U.S. homeowner researching a new furnace tax credit, you’re not alone. Rising energy costs and aging HVAC systems have many Americans asking: Does installing a new furnace qualify for a federal tax credit in 2026? The short answer is no—the primary federal incentive under the Energy Efficient Home Improvement Credit (Section 25C) expired on December 31, 2025.
This comprehensive guide breaks down everything you need to know: past federal tax credits for furnaces, why they ended, current alternatives like state and utility rebates, eligibility details from trusted sources, and practical steps to maximize savings on your furnace upgrade. Whether you’re in California, Texas, Florida, or New York, this USA-focused resource uses official IRS and ENERGY STAR data to help you decide if now is the right time to replace your furnace.
Current Status of Federal Tax Credits for New Furnaces in 2026
As of April 2026, there is no federal tax credit available for installing a new furnace. The Energy Efficient Home Improvement Credit (Section 25C), which previously covered high-efficiency natural gas, propane, and oil furnaces, officially ended for any equipment placed in service after December 31, 2025.
This change stems from updates under the One Big Beautiful Bill Act and the scheduled expiration of Inflation Reduction Act provisions. Homeowners who installed a qualifying furnace in 2025 (or earlier) may still claim the credit on their 2025 tax return if they haven’t filed yet. For 2026 and beyond, federal tax relief for furnaces has shifted away from tax credits toward income-based rebates in select states (more on that below).
Key takeaway: If your furnace installation is planned for 2026, focus on local utility rebates, state programs, and long-term energy savings rather than expecting a federal tax break.
What Was the Federal New Furnace Tax Credit (2023–2025)?
From 2023 through 2025, the Energy Efficient Home Improvement Credit allowed homeowners to claim 30% of qualified costs, up to $600 per furnace (as part of a $1,200 annual cap for most HVAC and envelope improvements).
- Credit cap for furnaces: $600 maximum per item.
- Combined annual limit: Up to $1,200 for furnaces, boilers, central air conditioners, insulation, windows, and doors.
- Heat pumps had a higher separate cap: $2,000 (but this doesn’t apply to standard gas or oil furnaces).
The credit covered labor and installation costs for qualifying residential energy property. It applied to existing homes (primary residence or second home) in the United States and was available to homeowners and, in some cases, renters making eligible improvements.
This program was designed to encourage high-efficiency upgrades under the Inflation Reduction Act, but it is now expired for new installations.
Eligibility Requirements for the Old Furnace Tax Credit
To qualify under the 2023–2025 rules (for anyone still claiming a prior-year credit):
- The furnace must have been new (not used or refurbished).
- It had to be placed in service (fully installed and operational) by December 31, 2025.
- Your home had to be an existing U.S. residence (not new construction).
- You (the taxpayer) had to live in the home as your primary or secondary residence.
- Business-use rules applied: Full credit if business use was 20% or less; prorated otherwise.
Important: Public utility rebates or subsidies had to be subtracted from your qualified expenses before calculating the credit.
Consult a tax professional or use IRS Form 5695 (Residential Energy Credits) if you installed in 2025 and are filing for that year.
Qualifying High-Efficiency Furnaces for Tax Credits
Only furnaces meeting strict efficiency standards qualified under the expired program:
- Natural gas furnaces: ENERGY STAR certified with Annual Fuel Utilization Efficiency (AFUE) of 97% or higher (meeting the highest Consortium for Energy Efficiency (CEE) tier, excluding advanced tiers).
- Oil furnaces: ENERGY STAR certified and rated for fuel blends with at least 20% biodiesel, renewable diesel, or second-generation biofuel.
- Propane furnaces: Similar CEE highest-tier requirements as natural gas models.
Manufacturers provided a Qualified Manufacturer Identification Number (QMID) or product PIN for 2025 claims. Homeowners could verify eligibility using the Department of Energy’s Tax Credit Product Lookup Tool or ENERGY STAR’s qualified product lists.
Pro tip: Even without a tax credit in 2026, choosing an ENERGY STAR-certified furnace with 95%+ AFUE still delivers significant energy savings—often 10–20% lower heating bills compared to older 80% AFUE models.
How Much Could You Save Under the Previous Credit?
For a typical $4,000–$8,000 furnace installation (including labor):
- Maximum credit: $600 (30% of up to $2,000 in qualifying costs).
- Combined with other upgrades (e.g., insulation or a new AC), total credits could reach $3,200 per year.
Real-world example: A $6,000 high-efficiency gas furnace replacement could yield a $600 non-refundable tax credit, reducing your net out-of-pocket cost.
How to Claim the Furnace Tax Credit (For 2025 Installations)?
- Gather documentation: Manufacturer’s certification, installation invoice with labor costs, and QMID/PIN.
- Complete IRS Form 5695, Part II.
- File with your federal tax return for the year the furnace was placed in service.
- Keep records for at least 3 years in case of audit.
The credit is nonrefundable—it reduces taxes owed but doesn’t result in a refund if it exceeds your liability.
State and Local Incentives Replacing Federal Tax Credits in 2026
With the federal 25C credit gone, many states and utilities have expanded their own programs:
- Income-based rebates (HEEHRA/HOMES programs): In participating states, low- to moderate-income households (up to 150% of area median income) can receive point-of-sale rebates up to $8,000 for high-efficiency electric equipment like heat pumps (often replacing gas furnaces). Some programs also cover efficient gas furnaces or boilers.
- Utility company rebates: Major providers like PG&E, Xcel Energy, and Con Edison offer $500–$2,000+ rebates for ENERGY STAR furnaces in many regions.
- State-specific tax credits: A handful of states (e.g., Colorado offers $1,000 for qualifying HVAC upgrades) maintain their own incentives.
- Local programs: Check your state’s energy office or DSIRE.org (Database of State Incentives for Renewables & Efficiency) for the latest.
Action step: Visit your utility’s website or energy.gov’s Home Energy Rebates Portal to see what’s available in your zip code. Many rebates are “stackable” with manufacturer warranties or financing offers.
Benefits of Upgrading to a New High-Efficiency Furnace in 2026
Even without a federal tax credit, a new furnace pays for itself through:
- Lower energy bills: 97% AFUE models can save hundreds annually.
- Improved comfort and air quality: Better humidity control and filtration.
- Increased home value: ENERGY STAR upgrades appeal to buyers.
- Warranties and reliability: Most new units come with 10–20 year parts warranties.
- Environmental impact: Reduced carbon emissions (especially if switching to heat pumps).
Common Mistakes to Avoid
- Assuming a federal credit still exists in 2026.
- Buying a non-qualifying (lower-efficiency) unit expecting rebates.
- Forgetting to subtract utility rebates from any remaining credit calculations.
- Skipping professional installation—improper sizing voids efficiency gains and warranties.
- Not getting multiple quotes or checking contractor credentials (NATE-certified is ideal).
