The confusion is real. Reddit threads are full of panic about expired credits. Here's what actually survived, what didn't, and exactly how much you can claim this year.
If you've spent any time on Reddit or HVAC forums lately, you've probably seen the same question repeated dozens of times: "Did the IRA tax credits expire?" The short answer is no, not all of them. But the long answer matters a lot more, because which credits survived, how much they're worth, and what equipment actually qualifies are details that can mean the difference between saving $2,000 on your next HVAC purchase or leaving that money on the table entirely.
The Inflation Reduction Act, signed in 2022, created several overlapping programs with different timelines, different eligibility rules, and different rollout schedules depending on your state. Some pieces launched immediately. Others are still being implemented in 2026. And a few provisions that people assumed were permanent were actually time-limited. No wonder everyone is confused.
This article cuts through the noise. We'll cover the two main federal programs still active in 2026, walk through the specific dollar amounts for heat pumps, air conditioners, and other qualifying equipment, and explain what paperwork you actually need to file. We'll also flag the common mistakes that cause people to miss out on credits they were entitled to.
The IRA created multiple incentive pathways. For homeowners buying HVAC equipment in 2026, two matter most:
This is the big one for most homeowners. Section 25C covers 30% of qualified expenses for energy-efficient home improvements, including heat pumps, central air conditioners, furnaces, water heaters, insulation, windows, doors, and home energy audits. It has specific dollar caps depending on what you're buying, and it resets every year. That annual reset is important, and we'll come back to it.
Section 25D covers a different category: solar panels, geothermal heat pump systems, wind energy, fuel cells, and battery storage. If you're installing a geothermal heat pump (the kind that uses underground loops, not an air-source unit), this is your credit. It covers 30% of total installed cost with no annual dollar cap through 2032. For most HVAC-only purchases, though, Section 25C is the relevant one.
Section 25C has a layered cap structure that trips people up. The overall annual limit is $1,200 for most improvements, but heat pumps and heat pump water heaters get a separate, higher cap. Here's how it breaks down:
| Equipment Type | Credit Rate | Maximum Credit |
|---|---|---|
| Heat Pumps (air-source) | 30% of cost | $2,000 per year |
| Heat Pump Water Heaters | 30% of cost | $2,000 per year |
| Central Air Conditioners | 30% of cost | $600 per year |
| Gas Furnaces (ENERGY STAR) | 30% of cost | $600 per year |
| Electrical Panel Upgrades | 30% of cost | $600 per year |
| Windows & Skylights | 30% of cost | $600 per year |
| Doors (exterior) | 30% of cost | $500 per year ($250 per door) |
| Insulation & Air Sealing | 30% of cost | Subject to $1,200 overall cap |
| Home Energy Audit | 30% of cost | $150 per year |
The $2,000 heat pump credit is separate from the $1,200 general cap. A homeowner who installs a qualifying heat pump AND new insulation could claim up to $3,200 in a single tax year ($2,000 + $1,200). Source: IRS.gov, Form 5695 instructions.
This is where many homeowners get tripped up. Not every heat pump or air conditioner qualifies for the credit. The IRS requires equipment to meet specific efficiency thresholds, and those thresholds are tied to the ENERGY STAR program's "Most Efficient" designation or the Consortium for Energy Efficiency (CEE) highest tier.
For 2026, these are the minimum efficiency ratings your equipment needs to hit:
- SEER2 rating: 16 or higher (this measures cooling efficiency)
- HSPF2 rating: 8.5 or higher (this measures heating efficiency)
- EER2 rating: Check manufacturer specs against ENERGY STAR requirements
Most modern inverter-driven heat pumps from major manufacturers meet or exceed these thresholds. If you're buying a system rated 17 SEER2 or above, you're almost certainly in qualifying territory. But always verify against the ENERGY STAR certified product list before purchasing.
- Must meet ENERGY STAR Most Efficient criteria for the current year
- Maximum credit: $600 (falls under the $1,200 general cap)
- Must be ENERGY STAR certified
- AFUE of 97% or higher is typically required for the highest tier
- Maximum credit: $600 (falls under the $1,200 general cap)
The High-Efficiency Electric Home Rebate Act (HEEHRA) is a separate program from the tax credits above, and it's the source of most of the confusion online. HEEHRA provides point-of-sale rebates (meaning discounts applied at the time of purchase, not claimed on your taxes later) for electric appliances, including heat pumps, heat pump water heaters, electrical panel upgrades, and insulation.
Here's the catch: HEEHRA is administered by individual states, and each state has to set up its own program, application process, and approved contractor network. Some states launched their programs in 2025. Others are still rolling out in 2026. A handful haven't finalized their programs yet.
- Income-based: Full rebates are available to households earning less than 80% of their area's median income. Partial rebates (50% of costs) are available up to 150% of area median income. Above that threshold, you don't qualify for HEEHRA but you still qualify for the Section 25C tax credit.
- Heat pump rebate: Up to $8,000 for qualifying heat pump installation (for income-eligible households)
- Electrical panel upgrade: Up to $4,000
- Insulation and air sealing: Up to $1,600
- Can be stacked with 25C: In most states, you can use HEEHRA rebates AND claim the Section 25C tax credit on remaining out-of-pocket costs, though the combined benefit cannot exceed total project cost.
To check whether your state's HEEHRA program is live, visit the Database of State Incentives for Renewables & Efficiency (DSIRE) or your state energy office website.
Every tax season, homeowners leave money on the table because of avoidable errors. Here are the most common ones we see:
Not all HVAC equipment meets the efficiency thresholds. A basic 15 SEER2 air conditioner likely won't qualify. Always check the ENERGY STAR certified product list or the manufacturer's tax credit documentation before you buy.
The IRS requires a Manufacturer Certification Statement (sometimes called a "tax credit certificate") to claim the credit. Your equipment manufacturer provides this, usually as a downloadable PDF on their website. Save it with your tax records. Without it, your CPA may not be comfortable claiming the credit.
Unlike one-time lifetime caps from previous tax code versions, the Section 25C credit resets every January 1. If you installed a heat pump in 2025 and plan to add insulation or a heat pump water heater in 2026, you can claim a new credit in each year. This creates real strategic opportunity for phased home upgrades.
A tax credit reduces your tax bill dollar for dollar. A $2,000 credit means $2,000 less in taxes owed. A deduction only reduces your taxable income, which is worth far less. The Section 25C benefit is a credit, which is the more valuable type. However, it's nonrefundable, meaning it can reduce your tax bill to zero but won't generate a refund beyond that.
Many states and local utilities offer their own rebates on top of the federal credit. These can range from $500 to several thousand dollars. The DSIRE database is the best tool for finding what's available in your zip code. Stacking federal, state, and utility incentives can significantly reduce your net cost.
Claiming the credit is simpler than most people expect, but you do need a few things ready at tax time:
- IRS Form 5695 - "Residential Energy Credits." This is the form where you report qualified expenses. It's filed as part of your regular federal tax return.
- Manufacturer Certification Statement - Proves the specific equipment model meets efficiency requirements. Download this from the manufacturer's website or request it from your supplier.
- Receipts and invoices - Keep all purchase receipts showing the equipment model number, cost, and date of installation. If you hired a contractor for installation, keep their invoice too. Labor costs for installation are included in the qualified expense calculation for Section 25C.
- Proof of installation date - The equipment must be installed and placed in service during the tax year you're claiming. A system purchased in December 2026 but installed in January 2027 would be claimed on your 2027 return.
Let's walk through two common scenarios to show what the credit actually means for your wallet.
| Scenario | Total Installed Cost | 30% Calculation | Credit Cap | Actual Credit |
|---|---|---|---|---|
| Heat pump system (3 ton, inverter, 17+ SEER2) | $7,500 | $2,250 | $2,000 | $2,000 |
| Heat pump + insulation + energy audit | $10,800 | $3,240 | $2,000 + $1,200 + $150 | $3,350 |
In Scenario 2, the homeowner claims the $2,000 heat pump credit plus up to $1,200 for insulation plus $150 for the energy audit, all in the same tax year. Source: IRS Form 5695 instructions.
For homeowners who also qualify for state-level HEEHRA rebates, the combined savings can be substantially larger. An income-eligible household in a participating state could potentially stack an $8,000 HEEHRA rebate with the $2,000 federal tax credit, reducing a $10,000 heat pump installation to a net cost near zero.
Beyond the tax credits, there's an equipment timing argument worth understanding. The AIM Act is phasing down production of R-410A, the refrigerant used in most HVAC systems sold over the last two decades. New equipment manufactured after January 1, 2025, uses lower-GWP refrigerants like R-32 or R-454B instead.
What does this mean for you? Two things:
- If your current system uses R-410A, servicing it will gradually get more expensive as the refrigerant supply tightens. Replacing an aging R-410A system now, while federal credits are available, locks in both the tax savings and a system running on a refrigerant with a longer future.
- New systems are designed for next-generation refrigerants. Equipment available at AC Direct in 2026 uses R-32 or R-454B, which are not being phased down. You're buying into the current technology cycle, not the end of the previous one.
Combine the refrigerant transition with active federal credits, and 2026 is genuinely one of the better years we've seen for the economics of upgrading. That's not a sales pitch. It's just how the timing lines up.
Here's something worth considering: the Section 25C credit covers 30% of your total cost. The lower your total cost, the faster you reach the cap, and the less you spend out of pocket after the credit is applied.
AC Direct sells qualifying heat pump systems at wholesale prices, the same equipment contractors buy from their distributors, shipped directly to you or your installer. There's no retail markup layered on top. When your equipment cost is lower to begin with, the $2,000 credit covers a bigger percentage of your actual spending.
For a practical example: if a heat pump system costs $7,500 through a traditional contractor (who marks up the equipment), your net cost after the $2,000 credit is $5,500. If you purchase the same qualifying system through AC Direct for less and hire your own installer, your total installed cost might come in at $5,800, making your net cost after the credit just $3,800. Same credit, same equipment, very different bottom line.
Our heat pump rebate page identifies which systems in our inventory qualify for the Section 25C credit and includes links to manufacturer certification statements.
Visit DSIRE or your state energy office to see if point-of-sale rebates are live in your area. If they are, apply for those first since they reduce your upfront cost.
Check the ENERGY STAR product list or ask AC Direct's team to confirm a specific model meets the 25C efficiency thresholds.
Purchase receipts, contractor invoices, manufacturer certification statement, and proof of installation date. Store digital copies in a "2026 Tax Credits" folder.
The system must be installed and operational in 2026 to claim the credit on your 2026 tax return. Don't wait until late December - contractor schedules fill up fast.
Your tax preparer should be familiar with this form. If you file yourself, the IRS instructions for Form 5695 walk through each line.
The IRA's HVAC tax credits did not expire. Section 25C is alive and well through at least 2032, offering up to $2,000 per year for qualifying heat pumps and up to $3,350 per year if you combine a heat pump with insulation and an energy audit. HEEHRA rebates are rolling out state by state and can stack on top for income-eligible households. The annual reset means you don't have to do everything at once.
The confusion online is understandable. There are multiple programs, multiple timelines, and state-level variables. But the federal tax credit itself is straightforward: buy qualifying equipment, install it in 2026, keep your paperwork, and file Form 5695. That's it.
The real risk isn't that the credits will disappear tomorrow. It's that homeowners keep waiting for clarity that's already here, while their aging systems rack up higher energy bills and run on refrigerants that are getting more expensive to service every year.
AC Direct carries a full lineup of Section 25C qualifying heat pumps at wholesale prices. No contractor markup. Manufacturer certification statements available for every qualifying model. Ships nationwide.
