How much is the Hawaii heat pump rebate?

Hawaii Energy: Mini-split VRF air conditioner up to $550. Central AC retrofit $1,250. Note: Hawaii's mild climate means these are cooling-focused rebates, not heating rebates. Space heating is rarely needed in Hawaii. Focus on HPWH for maximum rebate value.

These are primarily cooling rebates — Hawaii's climate does not typically require space heating.

For most Hawaii homeowners, the HPWH rebate ($500–$700) offers better ROI than the mini-split cooling rebate.

Cannot be combined with other Hawaii Energy incentives on the same equipment.

Not a guarantee of eligibility. Verify current amounts with your utility or Hawaii Energy Rebate Program.

Key factors that determine your Hawaii rebate

Your electric utility
Which utility serves your home (Hawaii Energy (statewide — Hawaiian Electric, HELCO, MECO, KIUC)) determines which rebate tier applies.
Current heating fuel
Oil and propane homes typically qualify for the highest tiers. Natural gas homes usually qualify for lower amounts.
Whole-home vs. partial scope
A whole-home heat pump installation that replaces all primary heating earns the highest rebate. Supplemental or mini-split-only installs earn less.
System size in tons
Larger systems generally earn higher rebates, up to the program cap. Oversizing can disqualify equipment in some programs.
Equipment certification
Equipment must meet the program's current efficiency threshold. Verify the AHRI reference number or program-specific certification before purchase.
Income qualification
Income-qualified households may receive enhanced rebates or additional assistance. Ask your utility about documentation requirements.
