Key factors that determine your Kentucky rebate

Your electric utility
Which utility serves your home (LG&E (Louisville Gas and Electric), Kentucky Utilities (KU)) 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.
