These are credits, not deductions
Tax credits reduce your tax bill dollar-for-dollar. A $2,000 credit means $2,000 less in taxes owed — much more valuable than a $2,000 deduction.
How Much Can You Get?
| Equipment | Credit | Maximum |
|---|---|---|
| Central Air Conditioner | 30% of cost | $600 maximum |
| Air Source Heat Pump | 30% of cost | $2,000 maximum |
| Natural Gas Furnace | 30% of cost | $600 maximum |
| Heat Pump Water Heater | 30% of cost | $2,000 maximum |
| Electrical Panel Upgrade | 30% of cost | $600 maximum |
| Home Energy Audit | 30% of cost | $150 maximum |
$1,200 Aggregate Annual Limit
For: AC, furnaces, boilers, electrical panels, insulation, windows/doors
$2,000 Separate Annual Limit
For: Heat pumps, heat pump water heaters, biomass stoves (separate from $1,200 limit!)
Key insight: The $2,000 heat pump limit is SEPARATE from the $1,200 limit. You could claim $1,200 for an electrical panel upgrade AND $2,000 for a heat pump in the same year = $3,200 total.
What Qualified
These were the rules for equipment placed in service in 2025, the credit's final year. They're here because plenty of contractors are still quoting the wrong ones, and because you may still be filing for a 2025 job. A lot of people were told "16 SEER2 and you're covered" — that was never the standard.
Central Air Conditioners ($600 max)
Split systems had to meet the CEE highest tier:
Heat Pumps ($2,000 max)
From January 1, 2025, qualification ran off a list, not a rating:
Why heat pumps get more: The $2,000 cap reflects federal policy favoring electrification and heat pump adoption. Learn more in our complete heat pump guide.
What Doesn't Qualify
- Equipment not meeting efficiency thresholds
- Repairs (only new equipment)
- Rental properties (primary residence only)
- New construction (existing homes only)
How to Claim the Credit
Verify Equipment Qualifies (Before Purchase)
Ask your contractor: "Does this equipment qualify for the 25C tax credit?"
Check ENERGY STAR Product Finder →Keep Documentation
- • Manufacturer's certification statement
- • Itemized receipt showing equipment cost, installation cost, date, address
- • Proof of payment
File with Your Tax Return
Complete IRS Form 5695 (Residential Energy Credits), Part II. Transfer credit to Schedule 3.
Get Form 5695 Instructions →Keep Records
Retain all documentation for at least 3 years after filing (IRS audit window), preferably longer.
Texas: Stacking with Utility Rebates
Federal tax credits can be combined with utility rebates — they're separate programs. Here's an example:
Heat Pump Installation in Oncor Territory
Total savings: $3,000 (25% off original cost)
Note: Utility rebates may reduce the cost basis for the tax credit. Consult a tax professional for specific situations.
Common Questions
Is this a refundable credit?
No. The 25C credit is nonrefundable—it can only reduce tax you owe, not generate a refund beyond that.
Can I claim it every year?
Yes, within limits. The annual caps reset each year. If you replace your AC this year ($600 credit) and add a heat pump water heater next year ($2,000 credit), both qualify.
Do I need to itemize deductions?
No. The 25C credit is available whether you itemize or take the standard deduction.
Does installation cost count?
Yes. The 30% credit applies to both equipment cost and installation labor.
What if I finance the purchase?
Financing doesn't affect credit eligibility. The credit is based on total cost, regardless of how you pay.
When Credits Expire
