Local Incentives
Louisville, KY Heat Pump Rebates & Incentives
Local and federal incentive programs can significantly reduce the cost of a new heat pump system. Here are the programs available to Louisville homeowners.
LG&E Residential Rebates
Up to $400LG&E offers a $400 rebate for qualifying air-source and ductless heat pumps, and a $300 rebate for qualifying heat pump water heaters.
Louisville-area LG&E customers can receive up to $400 for a qualifying heat pump through the utility's residential rebate program; Kentucky's Home Energy Rebates are not yet accepting applications. Palmetto can help homeowners identify eligible equipment, navigate the application process, and maximize available rebates.
Incentive information is based on publicly available data as of 2026 and may change. Contact program administrators to verify current availability and eligibility requirements.

Climate Zones
Louisville is in USDA Hardiness Zone 7, with cold winter snaps and hot, humid summer days. The area's design temperatures—5°F for heating and 92°F for cooling—help guide heat pump sizing and selection, so a system can handle both seasonal extremes. Palmetto understands Louisville's climate and can recommend an option suited to local conditions. Explore other zones below or enter your ZIP code to confirm your zone.
Climate Zone 1
Climate zone 1 is not typically seen within the United States outside of Alaska. It represents the coldest climates on the planet.
Climate Zone 1A
Avg. extreme winters: -60° to -55° F
Climate Zone 1B
Avg. extreme winters: -55° to -50° F
Louisville Electricity Prices
Kentucky electricity prices remain below the national average, but the trend still matters for Louisville homeowners planning heating and cooling costs.
The chart shows Kentucky’s electricity price rising from 11.5 cents per kilowatt-hour in 2021 to 13 cents in 2024, despite a small dip in 2023. The U.S. average reached 16.5 cents in 2024.
A heat pump can help each kilowatt-hour go further: it moves heat rather than generating it, delivering roughly two to three times the heating or cooling per unit of electricity compared with traditional HVAC systems.
Using less electricity for comfort can help soften the impact of future rate increases. A properly sized, well-maintained heat pump can offer lasting efficiency, though actual bills depend on rates, weather, and your home.
Price of Energy: Kentucky vs National Average
Louisville Area Utility Providers
For Louisville, LG&E is the utility shown here. Its 2023 electricity price was 12.4¢ per kilowatt-hour; 2024 utility data isn’t available yet.
LG&E’s 2023 price was below Kentucky’s 12.70¢ state average and the 16.0¢ national average. Rates vary by utility and region, so these broader averages don’t necessarily reflect what Louisville customers pay.
Electricity prices are one part of home energy costs. Heat pumps use electricity efficiently to heat and cool, so they can reduce total energy spending compared with traditional HVAC, even where electricity costs more.

Repair versus replace
When a heat pump is in need of repair it is worth considering whether a replacement would be a better investment. While each case is unique, we generally recommend investing in a new unit when repairs exceed $5,000.
A heat pump's lifetime is impacted by a number of factors including environment, use and the quality of the unit. It's important to choose the right unit for your climate zone and home's unique attributes.
When you are in need of repair, we recommend choosing a service provider that is an expert in the heat pump brand you have installed, and checking online reviews to ensure you are investing in the right level of service.
| Potential repair | Cost range | Description |
|---|---|---|
| Capacitor Replacement | $150 - $400 | Common issue when unit struggles to start or makes a humming noise. Capacitors store the electrical energy needed to start the compressor and fan motors. |
| Refrigerant Recharge | $250 - $750 | Needed when the system loses cooling or heating efficiency due to low refrigerant levels. Includes leak detection, repair of minor leaks, and recharging the system to the manufacturer-specified level. |
| Reversing Valve Replacement | $450 - $900 | Required when the unit cannot switch between heating and cooling modes. The reversing valve directs refrigerant flow and is unique to heat pump systems. |
| Compressor Replacement | $1,500 - $3,000 | Major repair needed when the unit fails to heat or cool entirely. The compressor is the heart of the system, circulating refrigerant between the indoor and outdoor coils. |
| Evaporator/Condenser Coil Replacement | $1,200 - $2,800 | Replacement needed when coils develop leaks or corrosion that cannot be economically repaired. Coil damage reduces heat transfer efficiency and can cause refrigerant loss. |
| Control Board Replacement | $500 - $1,200 | Required when the system has electrical failures or erratic behavior. The control board manages all system operations including defrost cycles, fan speeds, and compressor staging. |
| Full System Replacement | $4,500 - $8,000+ | When repairs exceed the value of the unit or multiple major components fail simultaneously. Includes removal of the old system and installation of a new heat pump with updated refrigerant lines and electrical connections. |
