Updated September 2026: current Arizona heat pump rebate rules
Arizona heat pump rebates are still available in 2026 for eligible households, but the rules changed on September 1, 2026. Efficiency Arizona now limits federally funded appliance rebates to qualifying electric-to-electric upgrades and no longer allows a rebate when a fossil-fuel HVAC system is removed and replaced with an electric heat pump.
The former federal Energy Efficient Home Improvement Credit under Section 25C also should not be counted on for a new 2026 installation. Current IRS Form 5695 instructions state that energy-efficient home improvement credits cannot be claimed for property placed in service after December 31, 2025.
2026 Rebate Planning Snapshot
Check Eligibility First
Household, equipment, existing heating source, project type, and program rules can all affect eligibility.
Confirm Timing
Some programs require approval or documentation before installation. Verify the sequence before work begins.
Do Not Design Around a Rebate
Select the system around the home’s load and performance needs, then confirm which incentives apply to that design.

How Much Can Efficiency Arizona Cover?
Efficiency Arizona currently separates approved households into two income tiers:
- Tier 1 — household income below 80% of Area Median Income (AMI): up to 100% of eligible heat-pump project cost, capped at $8,000 for the heat pump measure.
- Tier 2 — household income from 80% to 150% of AMI: up to 50% of eligible heat-pump project cost, capped at $8,000.
- Above 150% AMI: not eligible for the HEAR rebate program.
AMI depends on location and household size. Use the current Efficiency Arizona eligibility process rather than an old income table copied from another site.

Which Heat Pump Projects Are Eligible Now?
Under the current rules, the new heat pump must meet program product requirements and the project must fit an eligible replacement or addition pathway.
- Replacing an electric furnace with a qualifying heat pump.
- Replacing electric baseboard heating with a qualifying heat pump.
- Replacing a less-efficient existing heat pump with a qualifying heat pump.
- Adding a qualifying heat pump in addition to an existing HVAC system, where the program approves the project.
The new heat pump must be a qualifying ENERGY STAR-rated product. Efficiency Arizona also lists installation requirements that include ACCA Manual J load calculation, Manual S equipment selection, and quality-installation standards.
This fits the same sizing-first approach explained in our heat pump sizing and Manual J guide.
Important: Propane-to-Heat-Pump Replacement Is No Longer Rebate Eligible Under the New Rules
Efficiency Arizona changed its program rules effective September 1, 2026. New rebate reservations can no longer be used to remove a gas or other fossil-fuel appliance and replace it with an electric appliance.
For Kachina Village homeowners, that is especially important because propane heating is common. Do not assume that replacing a propane furnace with an all-electric heat pump qualifies for the current Efficiency Arizona rebate.
The program does state that a heat pump may be added in addition to an existing HVAC system. If you are considering a dual-fuel or add-on project that keeps the propane furnace, confirm the exact project configuration with Efficiency Arizona before signing a contract. Do not assume eligibility from the equipment alone.
For system options independent of rebate eligibility, see dual-fuel heat pumps and heat pump vs. propane.
Existing Heat Pump Replacement Can Qualify
This is another major change from the older program guidance. Efficiency Arizona’s current FAQ says an existing heat pump can now be replaced with a new, more efficient qualifying heat pump and receive a rebate if the household and project meet the other requirements.
That makes the program potentially relevant to homeowners whose current heat pump is aging or inefficient, not only first-time heat-pump buyers.
If your system is already failing, compare the project itself first on the heat pump replacement page, then verify rebate eligibility before installation.
You Must Apply Before the Project Is Completed
Efficiency Arizona does not provide rebates for already-completed installations. The program requires approval and uses an Efficiency Arizona-qualified contractor pathway for contractor-installed heat-pump projects.
- Apply through Efficiency Arizona.
- Complete income and property eligibility review.
- Complete any required home assessment.
- Work through the program’s qualified-contractor process.
- Confirm the proposed equipment and project scope are eligible.
- Confirm the estimated rebate and your out-of-pocket balance.
- Proceed with installation only after the required program approvals are in place.
- Complete final documentation and verification required by the program.

Electrical Panel and Wiring Rebates
Efficiency Arizona currently lists up to $4,000 for an eligible electric load service center upgrade and up to $2,500 for eligible electrical wiring. These electrical measures must be associated with an eligible appliance project.
This can matter when a heat-pump project requires new circuits, breaker capacity, wiring, a panel change, or other electrical work. It does not mean every heat-pump installation automatically qualifies for the full electrical rebate.
Insulation and Air Sealing May Be Part of the Heat Pump Project
The current Efficiency Arizona rules state that insulation and air sealing may be required alongside a rebated heat-pump project. The program lists up to $1,600 for eligible insulation, air sealing, and ventilation measures.
That can be useful for high-country homes because reducing the building’s heating load can change the size and backup-heat requirements of the final system.
The Federal 25C Heat Pump Credit Ended for New 2026 Installations
Older articles may still describe a federal credit of up to $2,000 for qualifying heat pumps. That information applies to earlier eligible tax years, not a new heat pump placed in service in 2026.
The IRS’s 2025 Form 5695 instructions state that the Energy Efficient Home Improvement Credit cannot be claimed for property placed in service after December 31, 2025.
If you are dealing with a 2025 installation or an amended prior-year return, speak with a qualified tax professional and use current IRS guidance. This page is not tax advice.
What About APS Rebates?
Kachina Village’s local utility information identifies Arizona Public Service (APS) as the electric utility. Current Arizona incentive resources list APS energy-efficiency programs for measures such as duct sealing, insulation, smart thermostats, and certain HVAC or air-conditioning upgrades.
Because utility programs and rebate amounts change, do not assume a separate APS heat-pump equipment rebate unless a current APS program specifically confirms one for the project. Check APS directly before treating any utility incentive as part of the budget.
Can Rebates Be Stacked?
Some incentives can be combined, but stacking depends on the rules of each program and the same project cost generally cannot be reimbursed beyond the eligible amount. The Arizona Clean Energy Hub advises homeowners to verify the rules for federal, state, local, utility, and other incentives before combining them.
Because the federal 25C credit ended for new 2026 installations, do not use older stacking examples that assume a current 25C heat-pump credit.
What Should You Verify Before Counting on a Rebate?
- Your current household income tier and AMI eligibility.
- Property ownership and occupancy requirements.
- Your existing heating equipment type.
- Whether the project is electric-to-electric, an existing heat-pump replacement, or an approved add-on configuration.
- Whether the proposed product is on the qualifying list.
- Whether the project requires insulation or air sealing.
- Whether electrical work is eligible with the appliance project.
- Whether the contractor and project pathway meet Efficiency Arizona rules.
- Whether approval must be completed before ordering or installing equipment.
- Whether any utility incentive is actually active for your address.
- Your final out-of-pocket amount after the approved rebate—not the advertised maximum.
Do Not Choose the Wrong Heat Pump Just to Chase a Rebate
A rebate reduces project cost; it does not make unsuitable equipment suitable. For Kachina Village and Flagstaff-area homes, the proposed system still needs to make sense for the home’s heating load, low-temperature capacity, backup-heat strategy, ductwork, electrical system, snow clearance, and defrost drainage.
Before choosing equipment, review cold-climate heat pumps, heat pump sizing, and heat pump installation cost.

Not under the new rules for rebate reservations made on or after September 1, 2026. Efficiency Arizona no longer allows federally funded rebates for replacing fossil-fuel appliances with electric appliances. Add-on or dual-fuel configurations should be confirmed directly with the program before contracting.
Is the federal 25C heat pump tax credit available for a 2026 installation?
No for a new 2026 installation. Current IRS Form 5695 instructions state that the Energy Efficient Home Improvement Credit cannot be claimed for property placed in service after December 31, 2025.
Do I need to apply before installation?
Yes. Efficiency Arizona does not provide rebates for already-completed installations. The project must follow the program's approval and qualified-contractor process.
Are electrical panel and wiring rebates available?
Potentially. Efficiency Arizona lists up to $4,000 for an eligible electric load service center and up to $2,500 for eligible wiring when tied to an eligible appliance project.
Can I count on an APS heat pump rebate too?
Do not assume one. Utility programs change. Check APS directly for current programs that apply to the specific address and project before including a utility rebate in the budget.
