That means chilly winter stretches and hot summers, so a heat pump must handle both occasional cold snaps and strong cooling demand. Palmetto understands Fort Mill’s climate and can recommend a system suited to local conditions. Explore other zones below or enter your ZIP code to confirm your zone.

Fort Mill Electricity Prices
For Fort Mill homeowners, the electricity rate is only part of the energy-bill picture.
South Carolina’s average electricity price rose from 12.9 cents per kWh in 2021 to 14.1 cents in 2024, though it remained below the national average.
Heat pumps use less electricity per unit of heating or cooling delivered and can be 2–3 times more efficient than traditional HVAC systems, helping each kilowatt-hour go further.
Over time, using less electricity for year-round comfort can help Fort Mill households manage rising energy costs. Actual savings depend on your home, system, and energy use.
Price of Energy: South Carolina vs National Average
Fort Mill Area Utility Providers
In Fort Mill, Duke Energy’s 2023 electricity rate was 12.7¢ per kWh—below South Carolina’s 13.70¢ state average and the 16.0¢ national average. 2024 utility data is not yet available.
Electricity rates vary with each utility’s energy supply, rate structure, and grid costs. These factors can help explain differences between averages, but the figures alone don’t show which ones account for Duke Energy’s lower 2023 rate.
Even where electricity costs more, a heat pump’s high efficiency can reduce the energy needed to heat and cool a home. Compared with traditional HVAC, it may lower total energy spending, depending on the home and how it’s used.

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. |
