How to Save Up to $2,000
The federal Section 25C tax credit for mini splits ended on December 31, 2025. Congress did not extend it. Systems installed in 2026 don't qualify for the $2,000 federal credit you've probably read about, even on pages that were updated this year.
That doesn't mean a new mini split has to cost you full price in 2026. If your system was up and running before the end of 2025, the credit is still yours. File IRS Form 5695 with your 2025 return. If you're shopping for a system this year, state and utility rebates in many parts of the country now add up to more than the old federal credit ever paid out. Mass Save in Massachusetts goes to $8,500. Energize Connecticut tops out near $15,000 when the new system replaces oil or propane heat. Even modest utility rebates run a few hundred to a few thousand dollars, depending on your provider.
This guide covers both paths. The Filterbuy team works with these programs every week, so the figures and dates here come from the install truck. We've also lined up our own mini-split lineup — the 12,000 BTU (115V and 230V), 18,000 BTU, and 24,000 BTU R-32 heat pump models — with the spec sheet that most 2026 rebate programs are paying for. Where the credit math depends on the equipment you pick, we say so.
The federal $2,000 mini split tax credit (Section 25C) expired on December 31, 2025. Systems installed in 2026 don't qualify. The rebate math has shifted, not disappeared.
What's still on the table in 2026:
State programs: Mass Save up to $8,500, Energize CT up to $15,000, NYS Clean Heat varies by zone.
HEEHRA federal rebates: Up to $8,000 at the point of sale for income-qualified households.
Utility company rebates: $300 (Duke Energy) to $1,800 (Seattle City Light), depending on your provider.
2025 installs still qualify: File IRS Form 5695 with your 2025 return to claim the $2,000 federal credit.
Filterbuy mini splits are spec'd for the rebates: R-32 refrigerant, 17 SEER variable-speed inverter, ENERGY STAR–aligned. 12K (115V/230V), 18K (230V), and 24K (230V) heat pump models with a 5-year compressor warranty.
In many ZIP codes, the remaining rebates stack to more than the old federal credit ever paid out alone.
The federal $2,000 mini split tax credit (Section 25C) ended on December 31, 2025, terminated seven years early by the One Big Beautiful Bill Act.
2025 installs are still claimable on your 2025 return using IRS Form 5695, with the AHRI certificate and manufacturer's QMID required.
State, utility, and HEEHRA rebates in many ZIP codes now stack to more than the old $2,000 federal credit ever paid out alone.
Pre-approval before installation is the rule that catches people every year, because contractors cannot apply for state or utility rebates retroactively.
Spec the system for the rebate, not the code minimum. Most 2026 programs require ENERGY STAR certification, low-GWP refrigerant (R-32 or R-454B), and a variable-speed inverter compressor. Every Filterbuy mini split, 12K, 18K, and 24K BTU are built to that spec.
The Inflation Reduction Act of 2022 took the old Nonbusiness Energy Property Credit, which had been capped at $300, and turned it into something a homeowner could actually plan around. Under the new Section 25C, you could claim 30% of what you paid for a qualifying heat pump (equipment plus labor) up to $2,000 a year. The credit was supposed to run through 2032.
Then Congress passed the One Big Beautiful Bill Act (Public Law 119-21) on July 4, 2025, which moved the §25C termination date forward by seven years. The new cutoff was December 31, 2025. Section 25D, the residential clean energy credit used for solar and geothermal, ended on the same date.
Two details from the IRS guidance still matter if you're close to that deadline. First, the controlling date is "placed in service," meaning the day the system is installed, operational, and ready to use. Buying the equipment in December 2025 didn't count if the contractor commissioned it in January. Second, the credit is non-refundable and doesn't carry forward. If your 2025 federal tax bill came in below $2,000, the unused portion of the credit was lost.
Mini splits, formally called ductless heat pumps, fall under §25C as a heat pump improvement rather than central air conditioning. Because mini splits handle both heating and cooling from one outdoor unit, they qualified for the full $2,000 cap. Cooling-only AC topped out at $600.
The IRS FAQ on Public Law 119-21 is the primary source on how the OBBBA changes work. It's the document our CPA reviewer points homeowners back to when timing questions come up.
If your installer finished commissioning your system in 2025, you're filing for it now. The rules below are what the IRS will check.
System was placed in service on or before December 31, 2025.
System is a heat pump that provides both heating and cooling. Cooling-only mini splits don't qualify under the heat pump category.
System meets the CEE Highest Tier efficiency thresholds for SEER2, EER2, and HSPF2 (see table below).
System carries ENERGY STAR Most Efficient 2025 certification.
Manufacturer is registered with the IRS as a qualified manufacturer, and you have the four-digit Qualified Manufacturer Identification Number (QMID, sometimes called PIN) for Form 5695.
Installed at your primary residence in the United States. Rentals and second homes don't qualify.
You have an AHRI Certificate matching the outdoor and indoor units exactly as installed.
Mini splits had to clear a higher efficiency bar than central ducted heat pumps. These are the thresholds that controlled eligibility for 2025.
| Mini Split Type | SEER2 (≥) | EER2 (≥) | HSPF2 (≥) | Cold-Climate |
|---|---|---|---|---|
| Ductless mini split | 16.0 | 9.0 | 9.5 | COP ≥ 1.75 at 5°F |
| Ducted heat pump (for context) | 15.2 | 10.0 | 8.1 | Same |
All three brands had multiple models on the CEE Highest Tier list for 2025. Eligibility was always tied to the specific model pairing, not just the brand on the box. The exact outdoor unit paired with the exact indoor head, as written on your AHRI Certificate, is what the IRS verifies on audit.
If you're filing now and want to confirm eligibility, pull your AHRI Reference Number off the contractor invoice and plug it into the AHRI Certified Products Directory. Cross-check the result against the ENERGY STAR Air-Source Heat Pump tax credit page. If both confirm the system, you're clear to file.
Whichever brand you installed, the system only stays at the efficiency you bought if the air filter is doing its job. Filterbuy ships the right filter size on the right schedule, so the equipment you spent thousands on doesn't quietly lose efficiency to a clogged mesh. Our month-to-month running cost guide breaks down where the operating savings actually come from over the life of the system.
If you qualify under the 2025 rules above, the filing process is straightforward. Most homeowners can handle it on their own. A tax professional is worth the call if your liability is anywhere near the credit cap.
Gather your paperwork. Itemized contractor invoice, AHRI Certificate, ENERGY STAR documentation, the manufacturer's QMID/PIN, and proof of the placed-in-service date (commissioning report, final invoice with the install completion date, or the inspector's sign-off).
Confirm eligibility before you file. If the system was placed in service after December 31, 2025, or if it doesn't hit CEE Highest Tier, stop here. The credit isn't available, and filing for it anyway puts you at audit risk.
Total your eligible cost. Equipment plus installation labor both count. Subtract any utility or state rebates you received before calculating the credit.
Calculate the credit. Thirty percent of the net cost, capped at $2,000 for the heat pump. The general $1,200 §25C cap doesn't apply to heat pumps. They have their own $2,000 line on Form 5695.
File IRS Form 5695 with your 2025 federal return. Heat pump expenses go on the heat-pump line of Part II. Enter the manufacturer's QMID where prompted.
Keep records for at least three years. The IRS may ask for the AHRI certificate, manufacturer PIN, and placed-in-service documentation if your return is selected for review.
The federal credit ended, but several other rebate programs are still funding mini split installs in 2026. The largest of these is HEEHRA, the federally funded program administered through state energy offices. State-specific programs like Mass Save and Energize Connecticut layer on top, and your electric utility may offer a rebate of its own. In many ZIP codes, all of those together pay out more than the old $2,000 federal credit ever did.
HEEHRA, the Home Electrification and Appliance Rebates program, is the federal piece that survived OBBBA. Congress funded it through the same Inflation Reduction Act that originally extended §25C. States are rolling out their HEEHRA programs at different speeds, but for income-qualified households, the rebate hits at the point of sale instead of at tax time.
Two income tiers qualify. Households under 80% of Area Median Income (AMI) can get up to $8,000 toward a qualifying heat pump. Households between 80% and 150% of AMI can get up to $4,000, which works out to half the cost of the install. Above 150% of AMI, HEEHRA doesn't apply, though state and utility rebates often still do.
HEEHRA is state-administered, which means each state runs its own program with its own contractor list and pre-approval rules. Funding is finite. California's TECH Clean California single-family pool fully reserved on February 24, 2026, and other states are following. Check the DOE Home Energy Rebates page for current rollout status before you commit to anything.
These five are representative, not exhaustive. Your state may have a different program, and the dollar amounts shift as funding cycles refresh.
| State | Program | 2026 Mini Split Benefit |
|---|---|---|
| Massachusetts | Mass Save | Up to $8,500 for whole-home heat pump conversion, or $1,125 per ton for partial. Stacks with HEEHRA where eligible. |
| Connecticut | Energize CT (Eversource and UI) |
$250 per ton for cooling-only or replacement. Up to $15,000 when the system fully displaces oil, propane, gas, or electric-resistance heat. Smart-E Loan at 0.99% APR through June 30, 2026. |
| New York | NYS Clean Heat | Tiered rebates by utility zone, with stronger incentives for cold-climate ASHPs and whole-home conversions. |
| California | TECH Clean California | HEEHRA single-family fully reserved as of February 24, 2026. Multifamily projects still active in some regions, with a waitlist open. |
| Washington | Seattle City Light + state HEEHRA | Approximately $1,500 to $1,800 utility rebate plus an $800 ductless mini split bonus. State HEEHRA portal in development. |
Programs change quickly. The two sources we trust to be current are the DSIRE database and the ENERGY STAR Rebate Finder. Both let you enter your ZIP code and see what applies in your area. Call the program directly before you sign anything with a contractor, since most require pre-approval and there's no retroactive paperwork that fixes a missed deadline.
Most homeowners don't think to check, but the company that bills you for electricity often pays you to install a heat pump. Duke Energy offers $300 to $1,000 for qualifying HVAC and heat pump replacements in its service territories. Seattle City Light pays roughly $1,500 to $1,800 plus an $800 ductless mini split bonus. Eversource and United Illuminating administer the Energize CT rebates in Connecticut. One rule catches people every year. Utility rebates require pre-approval before installation, which means your contractor cannot apply for them after the fact.
Even without the federal credit, a CEE Highest Tier mini split can lower your monthly operating costs against older central AC, electric resistance heat, or oil and propane heat. The U.S. Department of Energy notes that duct losses alone can account for more than 30% of the energy used to heat and cool a home with a central system. Mini splits eliminate that loss by design. Across a 12- to 15-year service life, those savings add up to more than the one-time tax credit ever paid.
Our month-to-month running cost guide walks through the operating math, including equipment draw, climate adjustments, filter replacement, and what to expect on the actual electric bill. If you're trying to decide whether the system pays for itself without the credit, that's the next page to read.
Across the systems our Filterbuy team installed in 2025, paperwork and timing caused more lost credits than equipment efficiency did. The same five patterns kept showing up.
The federal minimum SEER2 for new mini split installations is lower than the credit threshold. A perfectly legal-to-install system can still fail CEE Highest Tier. If the conversation with your contractor was just "this one meets code," that wasn't enough. Eligibility was always about the higher tier, not the legal floor.
The IRS uses the placed-in-service date. A unit bought on December 18, 2025, but commissioned on January 6, 2026, didn't qualify. The contract date, the delivery date, and the down-payment date were all irrelevant. What counted was the day the system was installed, operational, and ready to use.
If you got a $1,500 utility rebate on an $8,000 install, the credit was calculated on $6,500, not the original $8,000. Thirty percent of $6,500 is $1,950, which is what you could claim. A few filers learned that one the hard way at audit.
Starting in 2025, the IRS required a Qualified Manufacturer Identification Number on Form 5695. If your contractor didn't supply it, the manufacturer's website usually does. Filing without it is a fast disqualification.
Section 25C was always limited to a primary residence in the United States. We've seen homeowners try to claim the credit on a guest house, a vacation home, or an Airbnb. None of those qualified.
If you're shopping now and want the rebates that are still available, the spec sheet matters more than the brand on the box. State and utility programs in 2026 are looking for four things.
ENERGY STAR certification. Most state programs require it. Some require ENERGY STAR Most Efficient.
Refrigerant with a global warming potential of 700 or less. Per the EPA Technology Transition Rule (effective January 1, 2026), R-32 and R-454B systems qualify. Older R-410A systems generally don't for new rebate applications.
Variable-speed inverter compressor. Single-stage units rarely qualify. Inverter-driven systems are what utilities are willing to pay for, because they're what actually drops grid load.
Ductless heat pump configuration. Cooling-only units are excluded from heat pump programs across the board.
We built our mini split line around exactly the four boxes a 2026 rebate program checks. Every unit runs on R-32 refrigerant, uses a variable-speed DC inverter compressor, operates as a true heat pump (not cooling-only), and ships with ENERGY STAR–aligned efficiency. The differences across the line are size, voltage, and where each unit fits best in a real house.
R-32 refrigerant (GWP 675, well under the 700 cap most 2026 programs are using).
17 SEER variable-speed DC inverter compressor that ramps to match room demand instead of cycling fully on and off.
Heat pump operation down to 5°F for shoulder-season and moderate-cold heating without a backup source.
~30 dB indoor sound level on low fan, quiet enough for bedrooms and home offices.
Wi-Fi app control for scheduling, mode switching, and remote temperature checks.
1-year parts warranty + 5-year compressor warranty when professionally installed by a licensed HVAC contractor.
Free 2-day shipping from our U.S. warehouses.
Three numbers — square footage, voltage, and where the unit lives in the house — usually decide which model is right. Use the table as a starting point, then have your installer run a Manual J load calculation to confirm.
| Filterbuy Model | Capacity | Voltage | Best For | Notes |
|---|---|---|---|---|
| 12,000 BTU / 115V | 1 ton, ~300 sq ft | 115V | Bedrooms, home offices, finished attics, additions wired for standard household outlets | Plugs into the same circuit type as a typical room appliance — often the simplest install if 230V isn't already in the space |
| 12,000 BTU / 230V | 1 ton, ~300 sq ft | 230V | Same room sizes as the 115V, but installed where contractors prefer to work — laundry rooms, garages, workshops, and homes with existing 230V infrastructure | Half the amperage draw of the 115V at the same output. Smaller breaker, thinner wire, less strain on a tight panel |
| 18,000 BTU / 230V | 1.5 ton, ~350–400 sq ft | 230V | Master suites, large open living rooms, large 1-car or small 2-car garages, finished basements | The middle of the line. Where most whole-room conversions land |
| 24,000 BTU / 230V | 2 ton, ~500–550 sq ft | 230V | Open-concept main floors, full 2-car garages, sunrooms, light commercial spaces | The top of the single-zone line. Pair with a second 12K or 18K head when you need to condition two rooms |
In 2025 install jobs, the homes that benefited most from a single-zone mini split were rarely the ones a builder originally planned ductwork for. Brick rowhouses, Cape Cods with finished attics, additions framed onto homes whose original ductwork was never extended, garages converted to home offices, all of them are spaces where a 12K, 18K, or 24K BTU ductless head solves a comfort problem central air can't reach. The line is sized for those rooms, with both 115V and 230V on the 12K, so the install doesn't get held up waiting on a panel upgrade.
If you're cross-checking a Filterbuy spec sheet against a state or utility rebate application, here's the translation:
R-32 refrigerant → satisfies the EPA Technology Transition Rule for low-GWP refrigerant. Most 2026 rebate forms ask for this directly.
17 SEER variable-speed inverter → above the federal SEER2 minimum and inside the range most utility rebates require for ductless heat pumps. Confirm the specific SEER2 threshold in your local program before submitting paperwork.
Heat pump (heating + cooling) → qualifies under heat pump rebate categories rather than cooling-only AC categories, which often pay less or nothing.
AHRI Certificate → included with every install when the system is professionally commissioned. The reference number on that certificate is what you'll plug into your rebate application and (for 2025 installs) the AHRI Directory.

Across our 2025 install jobs, the homeowners who saved the most money got rebate pre-approval before picking equipment. The rebate almost always covered the upcharge to a higher-efficiency mini split, so the more expensive system ended up cheaper out of pocket and lower on the electric bill every month after. — Filterbuy Team |

When a customer asks whether the mini split math still works without the federal credit, we walk through the same three federal datasets every time. All three come from the EIA's Residential Energy Consumption Survey, a federal sample of 123.5 million U.S. homes occupied in 2020.
Ask a homeowner where their bill goes and they guess the fridge or the dryer. The actual answer surprises most of them.
52% of a typical U.S. household's annual energy use went to space heating and air conditioning in 2020.
That's more than every appliance, every light, and every screen in the house combined.
What we see on installs. When the equipment driving over half the meter gets meaningfully more efficient, the bill moves with it. That's the math behind a high-efficiency mini split paying back without the federal credit.
Source: U.S. Energy Information Administration — Use of Energy in Homes (2020 RECS data, the most recent published consumption year).
EIA tracked four decades of central AC adoption. The same dataset shows where the boom stopped.
AC use overall: 57% of U.S. homes in 1980, 89% by 2020.
Central AC specifically: 27% in 1980, 67% by 2020.
What we see on installs. The houses central AC missed are exactly the homes our team sizes mini splits for: brick rowhouses, Cape Cods with finished attics, and additions framed onto homes whose original ductwork was never extended. The federal credit's expiration doesn't change which of those homes make sense for ductless. State and utility rebates pick up most of the slack — and our 12K, 18K, and 24K models are sized for exactly those rooms.
Source: U.S. Energy Information Administration — Electricity Use in Homes.
The national average annual cost of cooling a U.S. home is $265. That's the least useful number in the EIA dataset.
National average: $265 per year, or 12% of total home energy spending.
Temperate marine zone (West Coast): about $60 per year.
Hot-humid Southeast: $525 per year, and 27% of total home energy spending in those homes.
What we see on installs. We learned this on Connecticut jobs. A New England homeowner who just paid an oil-bill winter cares about heating savings. In central Florida, the conversation is entirely about cooling. The same mini split serves both, but the payback math runs in opposite directions. That's why state programs in different climates are funded at different dollar amounts for what looks like identical equipment on the spec sheet.
The $2,000 federal credit is gone, but the financial story of 2026 isn't a loss for homeowners. It's a shift in who saves the most.
Most coverage frames §25C's expiration as bad news. After a year of installs across New England, the Mid-Atlantic, and the Southeast, here's what we actually see on the ground.
You spent the money at installation, then waited until tax season for 30% back.
The credit was capped at $2,000.
The full credit only applied if your tax liability was high enough to absorb it.
Every year, we watched homeowners lose chunks of the credit because their tax bill came in below the cap.
HEEHRA pays at the point of sale, not at tax time.
Mass Save and Energize CT pay within weeks, as checks or bill credits.
No tax liability test applies.
For a homeowner with an income tax bill under $2,000, the 2026 rebate stack is genuinely more valuable than the old federal credit ever was.
Pre-approval is required by almost every state and utility program.
Your contractor cannot backfill the paperwork after installation.
The system spec has to clear the program's efficiency bar before equipment is ordered.
The 2025 installs that saved the most money on our jobs were the ones where the homeowner called the utility before they called us.
Two paths from here. Pick yours.
Pull your paperwork: AHRI Certificate, manufacturer's QMID/PIN, itemized invoice with the placed-in-service date.
Verify the system on ahridirectory.org. The IRS uses the same directory on audit.
Subtract rebates from the credit base. $1,500 utility rebate on an $8,000 install = credit calculated on $6,500.
File IRS Form 5695 with your 2025 return. Heat pump expenses go on Part II. Enter the QMID where prompted.
Keep records for three years in case of IRS review.
Check your programs first. Run your ZIP through DSIRE and the DOE Home Energy Rebates page. 20 minutes, shapes everything else.
Get pre-approval before signing with an installer. Most programs require it. No retroactive applications.
Spec the system to the rebate. ENERGY STAR certified. R-32 or R-454B refrigerant. Variable-speed inverter compressor. Ductless heat pump configuration. Filterbuy's 12K (115V/230V), 18K, and 24K models all clear that bar.
Match the unit to the room. 12K BTU for bedrooms, offices, and small additions. 18K for master suites, large living rooms, and finished basements. 24K for open main floors and full 2-car garages. When in doubt, size up — undersized systems run nonstop and burn through compressors.
Schedule installation for late October through mid-November. December gets squeezed by holidays, weather, and year-end rushes.
No. The federal Section 25C Energy Efficient Home Improvement Credit expired on December 31, 2025 under the One Big Beautiful Bill Act. Mini splits placed in service in 2026 don't qualify for the federal credit. State and utility rebates may still apply, depending on your ZIP code and household income.
It's a non-refundable tax credit rather than a deduction, which means it reduced your federal tax owed dollar-for-dollar up to $2,000 for a qualifying heat pump. Because §25C didn't allow carryforward, any unused portion of the credit was lost if your tax liability fell below the credit amount.
Ductless heat pump mini splits had to meet CEE Highest Tier specs. That meant SEER2 of 16.0 or higher, EER2 of 9.0 or higher, and HSPF2 of 9.5 or higher, plus a minimum COP of 1.75 at 5°F outdoor temperature. The system also needed ENERGY STAR Most Efficient 2025 certification.
Yes. Multiple models from each brand met the CEE Highest Tier for 2025. Eligibility was always model-specific, so verify your exact outdoor and indoor pairing in the AHRI Certified Products Directory and confirm ENERGY STAR Most Efficient certification before filing.
Match BTU to square footage first, then voltage to your panel. The 12,000 BTU model handles rooms up to about 300 sq ft and comes in both 115V (standard household outlet) and 230V (the contractor-preferred install). The 18,000 BTU 230V model fits 350-400 sq ft rooms — master suites, large living rooms, large garages. The 24,000 BTU 230V model is sized for 500-550 sq ft, including 2-car garages and open-concept main floors. All four run on R-32 with a variable-speed inverter compressor and a 5-year compressor warranty.
Eligibility is set by each program, not by the manufacturer, so you'll always need to check the rebate's spec list against the specific Filterbuy AHRI Reference Number on your install paperwork. That said, every model in our line is built to the four checkboxes most 2026 programs share: ENERGY STAR–aligned efficiency, R-32 (low-GWP) refrigerant, variable-speed inverter compressor, and heat pump (not cooling-only) configuration. Bring the AHRI Certificate to your rebate application and the program will tell you yes or no in writing.
Yes, on your 2025 federal tax return, which you file in 2026. File IRS Form 5695, include the manufacturer's qualified manufacturer identification number, and keep your AHRI certificate and itemized invoice. The placed-in-service date has to be on or before December 31, 2025.
Several layers are still active. State programs include Mass Save (up to $8,500), Energize CT (up to $15,000), and NYS Clean Heat. Utility rebates range from $300 at Duke Energy to roughly $1,800 at Seattle City Light, with most utilities falling somewhere in between. Federal HEEHRA point-of-sale rebates go up to $8,000 for income-qualified households. Programs vary significantly by ZIP code, so check DSIRE and your utility before installing.
No. Section 25C was limited to your primary residence in the United States. Rental properties, vacation homes, and investment properties were never eligible under this credit.
Congress has not introduced legislation to reinstate §25C as of May 2026. Any return of the credit would require new federal legislation. For now, state and utility incentives are the most reliable path to mini split savings.
If you're shopping for 2026, start by checking your state and utility programs. Get pre-approval before signing with an installer. Choose a system that meets the spec the rebate is paying for — and if a Filterbuy 12K, 18K, or 24K fits your room and your panel, you'll have one less box to chase down on the rebate form.
Browse Filterbuy mini split heat pumps, or read our month-to-month running cost guide to see what the system actually costs to run after the install is done.
