Can You Stack Heat Pump Rebates? State-by-State Stacking Rules (2026)

Yes — in most states, you can combine heat pump rebates from multiple programs on the same project. HEAR, HOMES, utility rebates, state tax credits, and local municipal programs can stack to cover $5,000–$20,000+ of a heat pump installation. But the rules vary by state, and getting the order wrong can cost you thousands. This guide covers how stacking works, what the limits are, and shows real dollar examples from 10 states.

The Short Version

✓ What stacks

HEAR + utility rebates + state tax credits + local municipal programs. Most states allow all of these to combine on the same project.

✓ HEAR + HOMES together

Yes, but for different items. HEAR for the heat pump, HOMES for insulation and air sealing. Not both for the same equipment.

✗ Federal tax credits

Gone. Sections 25C and 25D expired December 31, 2025. Nothing to stack at the federal level. Details →

⚠ The 100% rule

Total stacked incentives generally cannot exceed 100% of the project cost. This is the main federal guardrail on stacking.

How Heat Pump Rebate Stacking Works

A heat pump installation typically costs $12,000–$18,000 for a ducted whole-home system. In states with strong programs, you can apply multiple layers of incentives to bring that cost down significantly. Here are the layers, from largest to smallest.

Layer 1: HEAR — Up to $8,000 per heat pump

The Home Electrification and Appliance Rebates program is the largest single incentive available. It covers up to $8,000 per heat pump for households below 150% of Area Median Income (AMI). Below 80% AMI, HEAR can cover 100% of costs. At 80–150% AMI, it covers 50% up to the cap. Above 150% AMI, HEAR does not apply. Not every state has launched HEAR yet — check your state's status.

Layer 2: HOMES — Up to $4,000–$10,000 for whole-home projects

The Home Efficiency Rebates program rewards measured energy savings across your entire home. If your project achieves 35%+ energy reduction, HOMES pays up to $4,000 (above 80% AMI) or $8,000–$10,000 (below 80% AMI). HOMES and HEAR can apply to the same project for different components — HEAR for the heat pump, HOMES for insulation, air sealing, and other efficiency work.

Layer 3: Utility rebates — $200–$4,000

Your electric utility likely offers its own rebate, separate from state and federal programs. These range from $200 (small co-ops) to $4,000+ (PSE in Washington, Con Edison in New York). Utility rebates almost always stack with HEAR and HOMES because they come from different funding sources (ratepayer charges, not federal money).

Layer 4: State tax credits — $500–$10,000

A handful of states offer their own tax credits for heat pumps. Colorado has a $1,000 credit, New York covers 25% up to $10,000 for geothermal, Oregon offers the Residential Energy Tax Credit, and New Mexico has both a sustainable building credit and a geothermal credit. Tax credits always stack with rebates because they are a different type of incentive — they reduce your state taxes, not your upfront cost.

Layer 5: Local and municipal programs — $500–$5,500

Some cities and counties add their own incentives on top. Ann Arbor's A2ZERO adds $4,000–$5,500, Montgomery County's Electrify MC adds $2,500, and Minneapolis Green Cost Share stacks up to $14,000. These are the most commonly overlooked layer.

The stacking order matters

Most state programs calculate their rebate based on the total project cost before other incentives. But some programs reduce the eligible cost by the amount of other rebates already applied. Check your state's rules for the order of operations — applying in the wrong sequence can reduce your total by hundreds or thousands of dollars.

Real Stacking Examples by State

All examples assume a ducted cold-climate heat pump system with a total installed cost of $15,000. Actual amounts depend on your specific equipment, contractor, and income tier.

Colorado — Below 150% AMI

HEAR rebate: $8,000
Xcel Energy utility rebate: $2,250/ton (~$4,500 for 2-ton)
Colorado state tax credit: $1,000

Total stacked: ~$13,500

Out of pocket on a $15,000 project: ~$1,500

Wisconsin — Below 80% AMI

HEAR rebate (100% coverage): $8,000
HOMES whole-home rebate: up to $10,000
Focus on Energy instant discount: $400–$900

Total stacked: up to ~$18,900

Out of pocket: potentially $0 (100% rule caps total at project cost)

New York — DAC-designated area

Clean Heat Program (utility): $5,000–$12,000
EmPower+ (income-qualified): up to $24,000
Geothermal tax credit (25% up to $10,000): if applicable

Total stacked: $10,000–$24,000+

New York has the deepest incentive stack in the country. DAC (Disadvantaged Community) designation unlocks the highest utility tier.

Maryland — Potomac Edison territory

EmPOWER Maryland (75% of cost, max $15,000): $11,250
Switch-to-Electric bonus: up to $4,000
Midstream contractor rebate: $800–$1,700

Total stacked: ~$15,000+

Potomac Edison territory stacks deepest in Maryland. Other utilities (BGE, Pepco, Delmarva) offer the EmPOWER base but not the Switch-to-Electric bonus.

Michigan — Ann Arbor, below 150% AMI

MiHER (HEAR) point-of-sale rebate: $8,000
DTE Energy utility rebate: $150–$1,200
Ann Arbor A2ZERO: $4,000–$5,500

Total stacked: ~$12,200–$14,700

Ann Arbor is one of the best cities in the country for heat pump stacking because the municipal program layers on top of state and utility.

Maine — Income-qualified (Tier 3)

Efficiency Maine Tier 3 rebate: $9,000 (ducted whole-home)
Whole-home bonus (Mar–Dec 2026): $500
Home Energy Loan (0% APR): covers remainder

Total stacked: ~$9,500 + 0% financing

Maine does not have active HEAR for most homeowners yet, but Efficiency Maine's own income-tiered program is generous enough to stand alone.

Massachusetts — Whole-home conversion

Mass Save whole-home rebate ($2,650/ton, max 3.5 ton): $8,500
Sizing bonus: $500
Weatherization bonus: $500
HEAT Loan (0% APR, up to $50,000): covers remainder

Total stacked: ~$9,500 + 0% financing

Must use R-32 or R-454B refrigerant — R-410A systems are excluded from Mass Save.

New Hampshire — Above 150% AMI (HEAR not yet available)

NHSaves utility rebate: $250–$1,250/ton
NE Heat Pump Accelerator: $650/unit

Total stacked: ~$1,900–$4,150 (depending on system size)

When HEAR launches (expected mid-summer 2026), income-qualifying households will be able to add up to $8,000 on top. Projects started before HEAR launches are not retroactively eligible.

Rhode Island — Clean Heat RI

Clean Heat RI (60% of cost, max $11,500): $9,000
RI Energy per-ton rebate: $200–$400

Total stacked: ~$9,200–$11,900

Note: HEAR in Rhode Island does not cover heat pump HVAC — only electrical upgrades and appliances. Clean Heat RI is the primary program.

Texas — Austin Energy territory

Austin Energy rebates: ~$3,000
Austin Energy 0% APR financing: available
No state program, no HEAR: $0

Total stacked: ~$3,000

Texas shows the other end of the spectrum — stacking is limited because there is no state program and SECO has not launched HEAR. Most Texas utilities offer less than Austin Energy.

What you'll actually pay

On a $15,000 ducted heat pump installation: income-qualified households in strong-stacking states pay $0–$3,000 out of pocket. Above-income households in moderate states pay $8,000–$12,000. In limited states with no HEAR, expect $12,000–$15,000 — essentially the full cost minus a small utility rebate.

Common Stacking Mistakes

⚠ Starting work before HEAR launches in your state

HEAR rebates are not retroactive. If your state has approved HEAR funding but the program has not launched yet, installing a heat pump now means you cannot claim HEAR later. In states like New Hampshire, Connecticut, and Pennsylvania where launch is expected in 2026, waiting could save you $4,000–$8,000.

⚠ Applying for the wrong program first

Some programs calculate your rebate based on total project cost after other incentives. If you apply for a percentage-based program last instead of first, the eligible cost is lower and your rebate shrinks. Ask your contractor or state energy office about the optimal application order.

⚠ Assuming HEAR covers everyone

HEAR has income limits. Households above 150% AMI get no HEAR rebate. Households at 80–150% AMI get a partial rebate (50% of costs up to cap). Only households below 80% AMI get the full amount. If you are above 150% AMI, your stack is limited to utility + state programs only.

⚠ Missing the municipal layer

City and county rebates are the most overlooked stacking layer. Programs like Ann Arbor A2ZERO ($4,000–$5,500), Montgomery County Electrify MC ($2,500), and Minneapolis Green Cost Share (up to $14,000) can dramatically change the math. These are not listed in state or federal databases — check with your city directly.

⚠ Confusing HEAR with the expired federal tax credit

HEAR is a point-of-sale rebate — it reduces your upfront cost at the time of purchase. The old 25C credit was a tax credit you claimed on your federal return months later. They work differently and have different rules. The federal credit no longer exists. Full details →

Who Benefits Most From Stacking

✓ Best candidates for deep stacking

Households below 80% AMI in states with active HEAR programs (Colorado, Wisconsin, Michigan, North Carolina, Georgia, Arizona, Washington, Indiana). These households can stack HEAR (100% coverage up to $8,000) + utility rebates + HOMES for insulation work. Many can get a full system for $0–$2,000 out of pocket.

✓ Good candidates

Households at 80–150% AMI in states with HEAR + strong utility programs. The partial HEAR rebate (50% up to cap) plus utility rebates typically covers $4,000–$8,000 of a $15,000 project.

Moderate candidates

Households above 150% AMI in states with strong utility programs (New York, Maryland, Maine, Massachusetts). No HEAR, but utility and state programs alone can cover $2,000–$9,000 depending on the state.

Limited stacking available

Households in states without HEAR and with small utility rebates (Texas, Ohio, Florida, Idaho, South Dakota). Expect $0–$1,500 total rebates. The decision to install a heat pump in these states depends on energy savings, not incentives.

How to Apply for Stacked Rebates

The process varies by state, but here is the general sequence that works in most programs.

Check your income tier

Determine if your household is below 80%, 80–150%, or above 150% of your area's AMI. This determines HEAR eligibility and amount. Your state energy office or program website will have an AMI calculator.

Identify all available layers

Check your state guide for HEAR/HOMES status, then check your specific utility's rebate page, then search for city/county programs. Build a list of every rebate you are eligible for before contacting a contractor.

Get quotes from participating contractors

Many HEAR and utility programs require you to use approved or participating contractors. Ask the contractor which rebates they can apply at point of sale and which require separate applications.

Apply in the right order

If HEAR is a point-of-sale rebate in your state, it will be applied by the contractor at purchase. Utility rebates are sometimes instant (midstream) and sometimes mailed after installation. State tax credits are claimed on your annual return. Confirm the sequence with your program administrator.

What to Watch

HEAR launches in more states

As of March 2026, about a dozen states have launched HEAR. Dozens more have approved funding. Each new launch adds an $8,000 stacking layer for income-qualifying households. Check your state guide for the latest status.

IRA funding runway

HEAR and HOMES are funded by the Inflation Reduction Act. The total allocation is fixed — when a state's funds run out, the program closes. States with high demand (Colorado, Michigan) could exhaust funds in 2026 or 2027. The political environment around IRA funding continues to shift.

Utility program changes

Utility rebate programs reset annually. Amounts, equipment requirements, and eligibility rules can change each program year. Pennsylvania's Act 129 Phase IV expires May 2026, and APS in Arizona eliminated all residential rebates in 2026.

Frequently Asked Questions

Can you stack heat pump rebates from different programs?

Yes, in most states. Utility rebates, state-administered programs, and IRA-funded HEAR or HOMES rebates can typically stack together. The main rule is that total incentives generally cannot exceed 100% of project cost. Some states have additional restrictions — check your specific state guide for details.

Can HEAR rebates stack with utility rebates?

Yes. HEAR (Home Electrification and Appliance Rebates) is designed to stack with utility programs. The federal guidance allows HEAR to combine with other non-federal incentives as long as the total does not exceed the project cost. Most state HEAR programs explicitly allow utility stacking.

Can you stack HEAR and HOMES rebates on the same project?

Yes, but for different components. HEAR covers specific appliances (heat pumps, heat pump water heaters, electric panels, wiring). HOMES covers whole-home energy efficiency improvements measured by total energy savings. You cannot use both for the same piece of equipment, but you can use HEAR for the heat pump and HOMES for insulation, air sealing, and other efficiency work on the same project.

What is the maximum amount of rebates you can stack?

The practical maximum varies by state. In states with the deepest stacking (New York, Wisconsin, Maryland), income-qualified households can stack $15,000–$24,000 in combined rebates on a single project. The general rule is that total incentives cannot exceed 100% of project cost. Most homeowners above 150% AMI can realistically stack $2,000–$5,000.

Do state tax credits stack with rebates?

Yes. State tax credits (available in Colorado, New Mexico, New York, Oregon, South Carolina, and a few others) stack on top of rebate programs because they are a different type of incentive. A tax credit reduces your state income tax owed, while a rebate reduces your upfront cost. They do not count against each other.

Can I still claim a federal tax credit for a heat pump in 2026?

No. Federal heat pump tax credits under Sections 25C and 25D expired December 31, 2025. They were repealed by the One Big Beautiful Bill Act. There is no federal tax credit to stack in 2026. HEAR and HOMES are rebate programs, not tax credits.
