The HVAC Tax Credit "Cliff": How OBBBA Accelerated the December 2025 Deadline & What NJ Homeowners Must Do Now
On July 4, 2025, a single piece of legislation erased 7 years of HVAC tax credits overnight. Homeowners who planned to upgrade in 2026-2032 now have only 42 days left to claim $2,000-8,000 in federal incentives.
⏰ Only 42 days remaining until the December 31, 2025 deadline
December installation slots are 85% booked. Act this week to secure your tax credit savings.
Introduction: The "Tax Credit Cliff" No One Saw Coming
On July 4, 2025, President signed the One Big Beautiful Bill Act (OBBBA) into law. Buried in the legislation was a provision that would cost American homeowners billions: the immediate acceleration of HVAC tax credit expiration from 2032 to December 31, 2025.
This created an unprecedented "cliff" — homeowners lost 7 years of planned incentives overnight. What was supposed to be a gradual phase-out through 2032 became a hard stop in just 42 days from today.
The financial impact is staggering: $2,000-8,000 per household in lost tax credits. For Union County, NJ homeowners who were planning to upgrade their heating and cooling systems in 2026 or beyond, this is a wake-up call. The clock is ticking, and contractors are already booking December installations at capacity.

What Is the One Big Beautiful Bill Act (OBBBA)?
Legislative Background
The One Big Beautiful Bill Act (H.R.1, 119th Congress) was signed into law on July 4, 2025. This sweeping legislation addressed budget reconciliation and made significant changes to federal tax policy, including energy incentive programs.
While the bill covered numerous policy areas, Section 13401 specifically targeted residential clean energy tax credits established under the Inflation Reduction Act (IRA) of 2022.
How OBBBA Changed HVAC Tax Credits
Original Timeline (IRA 2022)
- • Credits available through December 31, 2032
- • 10-year program duration
- • Gradual phase-out planned
- • $60+ billion in incentives projected
New Timeline (OBBBA 2025)
- • Credits end December 31, 2025
- • Only 3-year program duration
- • Immediate cliff (no phase-out)
- • $42 billion in lost incentives

Why This Creates a "Cliff"
Unlike solar tax credits (which phase down gradually from 30% to 26% to 22%), HVAC credits drop from 30% to 0% overnight on January 1, 2026. There is no grace period, no phase-out, and no extension currently proposed.
- No warning period: OBBBA was signed just 6 months before the deadline, giving homeowners minimal time to plan upgrades.
- Contractors caught off-guard: HVAC contractors were unprepared for the sudden rush of December installations, leading to capacity constraints.
- Supply chain pressure: Equipment manufacturers face unprecedented demand for high-efficiency systems in a compressed timeframe.
What Homeowners Are Losing: The $8,000 Tax Credit Breakdown
Section 25C - Energy Efficient Home Improvement Credit
Qualifying Equipment:
- • Heat Pumps: 30% of cost, up to $2,000
- • Central AC: 30% of cost, up to $600
- • Furnaces: 30% of cost, up to $1,200
- • Boilers: 30% of cost, up to $1,200

- • Most expensive systems qualify for highest dollar amount
- • $25,000 geothermal system = $7,500 federal credit
- • Also ending December 31, 2025 (solar continues through 2032)

What You're Losing in 2026
The December 2025 Deadline: Why "Placed in Service" Matters
What "Placed in Service" Means (IRS Definition)
According to IRS guidelines, a system is "placed in service" when it is:
- ✓ Fully installed: All equipment is in place and connected
- ✓ Operational: The system is turned on and functioning
- ✓ Ready for use: You can immediately begin using the system for heating/cooling
What Does NOT Qualify:
- ✗ Equipment ordered but not delivered
- ✗ Equipment delivered but not installed
- ✗ Partial installation in progress
- ✗ Awaiting final inspection or approval
Timeline Reality Check
Today
Deadline
Days Remaining
Typical installation timeline: 3-6 weeks from initial consultation to completion
Holiday disruptions: Thanksgiving week (Nov 24-29) and Christmas week (Dec 22-26) — many contractors operate limited schedules
Effective working days: Only ~25-30 business days available for installations
Why You Can't Wait Until December
Risk Factors:
- Supply chain delays: Equipment lead time has increased from 2 weeks (October) to 4+ weeks (November)
- Contractor scheduling: December slots are 85% booked as of November 15
- Weather delays: Winter storms can postpone installations by days or weeks
- Permit processing: Some NJ municipalities require 1-2 week permit approval
- Inspection delays: Final inspection required for "placed in service" status
Action Timeline:
- This week (Nov 19-22): Schedule consultation with approved contractor
- Week 2 (Nov 25-29): Get quote, confirm equipment, secure December installation date
- Week 3 (Dec 2-6): Equipment ordered, permits submitted
- Week 4-5 (Dec 9-20): Installation window (avoid Christmas week if possible)
- Week 6 (Dec 23-31): Final inspection, system operational ✓
🚨 CRITICAL WARNING
Systems ordered in December but installed in January 2026 will NOT qualify for any federal tax credit. You must complete installation by December 31, 2025.
The Contractor Scheduling Crisis: December Installations Are Booking Fast
Industry-Wide Rush
National Trends:
- • HVAC contractors nationwide report 50-80% surge in December bookings
- • Most contractors fully booked for December by Thanksgiving
- • Wait lists forming for January installations (which won't qualify)
- • Emergency services prioritized over elective upgrades
Dimatic Control Data:
- • December calendar 85% full as of November 15
- • 47 heat pump installations scheduled for December 2025
- • Compared to 12 in December 2024 (4X increase)
- • Limited slots remaining for Union County homeowners
Supply Chain Concerns
- Heat pump availability: Most standard models still in stock, but high-efficiency ENERGY STAR models with SEER2 15.2+ are experiencing supply constraints
- Lead time increasing: 2-week lead time in October → 4-week lead time by mid-November. By early December, some models may require 6+ weeks
- Manufacturer warnings: Major brands (Carrier, Trane, Lennox) are advising contractors to order equipment early to guarantee availability
- Component shortages: Specific high-efficiency components (variable-speed compressors, smart controls) facing tighter inventory
What This Means for You
If You Wait:
- ✗ No available December installation slots
- ✗ Equipment may be backordered
- ✗ Pushed to January = $0 tax credit
- ✗ Pay full price with no federal incentive
- ✗ Lose $2,000-8,000 in savings
If You Act Now:
- ✓ Secure December installation slot
- ✓ Equipment ordered before stockouts
- ✓ Qualify for federal $2,000-8,000 credit
- ✓ Stack with NJ state rebates ($1,500-2,000)
- ✓ Total savings: $4,000-8,000+

"We've scheduled 47 heat pump installations for December 2025, compared to 12 in December 2024. The OBBBA cliff is creating unprecedented demand. Homeowners who wait until Thanksgiving week may not get a December slot, which means they'll miss the tax credit entirely. If you've been considering an upgrade, this week is the time to call."

How to Claim the Federal HVAC Tax Credit (Step-by-Step)
Required Documentation
- • Itemized invoice from contractor showing equipment and installation costs
- • Qualified Manufacturer Identification Number (QMID) for equipment
- • Proof of installation (certificate, permit, inspection report)
- • ENERGY STAR certification (contractor provides)
IRS Form 5695
You'll file IRS Form 5695 ("Residential Energy Credits") with your 2025 tax return in April 2026.
- • Part II: Energy Efficient Home Improvement Credit (Section 25C)
- • File with your 2025 tax return (due April 15, 2026)
- • Most tax software (H&R Block, TurboTax) handles Form 5695 automatically
- • Tax preparers are familiar with this form
When You Receive the Credit
Important: This is a tax credit, not an immediate rebate.
- • Credit is claimed on your 2025 tax return (filed in 2026)
- • Reduces your tax liability dollar-for-dollar
- • Refund timing: 2-4 weeks after filing (typical IRS timeline)
- • Unlike NJ rebates (instant), federal credits are processed with your tax return
Tax Liability Requirement
You must have federal tax liability to benefit from this credit.
Example: If you owe $3,000 in federal taxes, a $2,000 credit reduces what you owe to $1,000.
If no tax liability: The credit provides limited benefit. It does NOT carry forward to future years (use it or lose it).
Consult a tax professional to understand your specific situation.

FAQ: OBBBA HVAC Tax Credit Cliff (15 Questions)
1. Why are HVAC tax credits ending in 2025?
The One Big Beautiful Bill Act (OBBBA), signed July 4, 2025, accelerated the expiration date from 2032 to December 31, 2025 as part of budget reconciliation. The original Inflation Reduction Act (IRA) planned for credits through 2032, but OBBBA cut 7 years of incentives.
2. What is the One Big Beautiful Bill Act (OBBBA)?
OBBBA (H.R.1, 119th Congress) is federal legislation signed into law on July 4, 2025, that made sweeping changes to tax policy, including accelerating the expiration of clean energy tax credits for residential HVAC systems.
3. How much can I save with the HVAC tax credit before it expires?
You can claim up to $2,000 for heat pumps, $1,200 for furnaces/boilers, $600 for central AC, and $1,200 for smart thermostats under Section 25C. Geothermal heat pumps qualify for a 30% credit with no cap under Section 25D. Combined with NJ state rebates, total savings can reach $4,000-8,000.
4. Can I still claim the heat pump tax credit after December 31, 2025?
No. Systems must be installed and operational ("placed in service") by December 31, 2025 to qualify. If your installation is completed in January 2026 or later, you will not be eligible for any federal tax credit under Section 25C or 25D (for geothermal).
5. What HVAC systems qualify for the federal tax credit?
Qualifying equipment includes heat pumps (SEER2 15.2+, HSPF2 7.8+), central AC (SEER2 16+), furnaces (95%+ AFUE), boilers (95%+ AFUE), geothermal heat pumps, and approved smart thermostats. All must be ENERGY STAR certified and installed in your primary residence.
6. How do I claim the HVAC tax credit on my taxes?
File IRS Form 5695 (Residential Energy Credits) with your 2025 tax return in 2026. Your contractor will provide required documentation: itemized invoice, Qualified Manufacturer ID Number (QMID), ENERGY STAR certification, and proof of installation. Most tax software handles Form 5695 automatically.
7. Will HVAC tax credits be extended beyond 2025?
As of November 2025, there is no indication Congress will extend Section 25C or 25D credits beyond December 31, 2025. Homeowners should not count on an extension and should plan installations before the deadline.
8. Can I get a contractor to install my system before December 31?
It depends on contractor availability. As of mid-November 2025, most HVAC contractors report 50-85% of December installation slots are already booked. Contact contractors immediately to secure a December date. Have backup contractors in case your first choice is fully booked.
9. What happens if my installation isn't completed by the deadline?
If your system is not fully installed and operational by December 31, 2025, you will not qualify for any federal tax credit. "Placed in service" means the equipment must be functioning, not just ordered or delivered. Incomplete installations receive $0 credit.
10. Are there NJ state rebates in addition to federal tax credits?
Yes. New Jersey Clean Energy offers rebates up to $2,000 for heat pumps (stacks with federal $2,000). NJ utilities (PSE&G, JCP&L, Elizabethtown Gas) offer additional rebates of $500-1,500. Total savings can reach $4,000-8,000 when combining all programs.
11. Do I need tax liability to claim the HVAC tax credit?
Yes. The credit reduces your federal tax liability dollar-for-dollar. If you have no tax liability, the credit provides limited benefit. The credit does not carry forward to future years (use it in 2025 tax year or lose it). Consult a tax professional for your specific situation.
12. Can I claim the credit for a rental property or vacation home?
No. Section 25C and 25D credits apply only to your primary residence. Rental properties, vacation homes, and investment properties do not qualify for residential energy tax credits.
13. Does DIY installation qualify for the tax credit?
No. Equipment must be installed by a licensed professional HVAC contractor. DIY installations do not qualify for Section 25C credits. Smart thermostats also require professional installation (even though many are marketed as DIY).
14. Can I claim the credit if I ordered equipment in 2025 but install in 2026?
No. The date that matters is "placed in service" (installation completion), not order date or delivery date. If installation is completed in 2026, the system does not qualify for the 2025 tax credit, and no 2026 credit exists under OBBBA.
15. Can heat pumps really handle New Jersey winters?
Yes. Modern cold-climate heat pumps operate efficiently down to -15°F and maintain 150-200% efficiency in typical NJ winter temperatures (20-40°F). During rare extreme cold events (below 5°F), auxiliary electric heat activates. Many homeowners choose dual-fuel systems (heat pump + furnace) for maximum efficiency.
