Kentucky's Touchstone Energy Cooperatives Heat Pump Rebates
Applications open
The current 2026 cooperative network page publishes the offer and participating cooperative list without a fixed closing date; the member must confirm current funds with the local cooperative.
Mini-split coverage unclear
The network source says heat pump and cold-climate heat pump but does not expressly say ductless or mini-split.

- Income
- None published for the heat-pump tiers.
- Efficiency
- Replacement heat pumps must be ENERGY STAR certified; the enhanced tier requires an ENERGY STAR-certified cold-climate model. Electric resistance conversion requires at least 14.3 SEER2 and 7.5 HSPF2.
- Install
- The residence must be electrically heated and served by a participating cooperative. Resistance-conversion homes must be at least two years old; new manufactured homes also qualify. Contact the local cooperative before beginning to confirm eligibility and its submission process.
