QUICK ANSWER
Hawaii homeowners can stack Hawaii Energy Rebates rebates, federal HEEHRA rebates (up to $8,000 for heat pumps and $1,750 for heat pump water heaters for qualifying households), and the federal home improvement tax credit (30% back, up to $3,200/year) for combined incentives of $5,000–$12,000+ on major upgrades. These programs are independent and fully stackable: receiving a utility rebate does not reduce your federal tax credit.
