South Carolina Heat Pump Rebates & Incentives Guide

Quick Answer: South Carolina Heat Pump Rebates at a Glance

South Carolina's heat pump incentive landscape is fragmented. The state does not offer a universal residential rebate program. Instead, electric cooperatives and municipal utilities manage their own rebate and loan programs with unique rules, amounts, and eligibility requirements.

• Utility rebates and loans: Several electric cooperatives provide rebates, typically for ground-source heat pumps, or offer low-interest loans for high-efficiency heat pump installations. Rebate amounts can range from $1,000 to $20,000 in loan financing, depending on the cooperative.
• State loan programs: The South Carolina Energy Office administers the ConserFund Loan Program. However, this program targets public entities and nonprofits, not residential customers (South Carolina Energy Office, ConserFund Loan Program).
• Federal tax credits: IRS §25C allows homeowners to claim 30% of installation costs, up to $2,000 per year, for qualifying heat pumps. This credit can be used in addition to any utility rebate or loan you receive.

Availability and amounts vary by location and utility provider. Your first step should be to identify your electric cooperative or municipal utility and check their specific program page.

South Carolina Utility Rebates and Loan Programs for Heat Pumps

Each cooperative sets its own terms.

Palmetto Electric Cooperative: Buried Treasure Rebate Program

Palmetto Electric Cooperative offers rebates to members who install ground-source (geothermal) heat pumps. The rebate is $200 per ton of capacity, with a maximum of $1,000 per household (Palmetto Electric Cooperative, Buried Treasure Rebate Program, palmetto.coop/buried-treasure).

Rock Hill Utilities: SmartChoice and Great Rate Programs

Rock Hill Utilities runs the SmartChoice program, which offers rebates for heat pump replacements. Customers who qualify as all-electric may also access the Great Rate program, providing a discount of up to 4 cents per kWh on their electric bill. To qualify for Great Rate, the heat pump must be rated at a minimum 16 SEER, and the water heater must have a Smart Switch (Rock Hill Utilities, SmartChoice Rebates and Loans, cityofrockhill.com). Financing options for heat pumps are also available through the SmartChoice portal. Consult Rock Hill Utilities directly for current rebate amounts, as the source material does not specify a fixed figure.

Pee Dee Electric Cooperative: Energy Resource Conservation Loan Program

Pee Dee Electric Cooperative offers loans up to $7,500 for qualifying energy efficiency improvements, including high-efficiency electric heat pumps, dual-fuel systems, and ground-source heat pumps (Pee Dee Electric Cooperative, Energy Resource Conservation Loan Program, pdec.com). The loan can also cover insulation, storm windows, programmable thermostats, and related measures. Interest rates and exact terms vary; contact Pee Dee directly or visit their energy center page.

Blue Ridge Electric Cooperative: Heat Pump Loan Program

Blue Ridge Electric Cooperative (BREC) offers low-interest loans specifically for heat pump purchases. Loans under $1,500 can be financed for up to 42 months. Loans over $1,500 can be financed for up to 60 months for houses. The minimum loan amount is $1,000. Qualifying heat pumps must be rated SEER 15 or higher for houses and SEER 14 or higher for mobile homes. The customer must own the home or property to qualify (Blue Ridge Electric Cooperative, Heat Pump Loan Program, blueridge.coop/hvac). Contact BREC for current interest rates.

Berkeley Electric Cooperative: HomeAdvantage Loan Program

Berkeley Electric Cooperative offers HomeAdvantage Loans up to $20,000 for energy efficiency upgrades, including HVAC system replacements. Loans must demonstrate a reasonable return on investment as determined by Berkeley Electric Cooperative, and measures generally need to generate enough savings to repay the loan within the loan term (Berkeley Electric Cooperative, HomeAdvantage Loan Program, berkeleyelectric.coop). This program has the highest loan ceiling among the listed cooperative programs.

Dominion Energy: Commercial EnergyWise Program

Dominion Energy's EnergyWise program includes HVAC incentives, but it is primarily designed for commercial customers. Residential customers served by Dominion Energy in South Carolina should contact Dominion directly to inquire about any applicable residential HVAC programs (Dominion Energy, Commercial EnergyWise Program, dominionenergy.com).

State-Level Energy Efficiency Initiatives in South Carolina

ConserFund Loan Program

The South Carolina Energy Office administers the ConserFund Loan Program to fund energy efficiency improvements for state agencies, local governments, public colleges and universities, school districts, and private nonprofit organizations (South Carolina Energy Office, ConserFund Loan Program, energy.sc.gov). Residential homeowners are not eligible. Priority is given to projects with fast energy savings payback periods. ConserFund is typically used for retrofits of existing buildings, although exceptions exist. If you work for a qualifying public or nonprofit entity and are upgrading HVAC systems, inquire directly with the South Carolina Energy Office about current application deadlines and loan terms.

Distributed Energy Resource Program

S.B. 1189 of 2014 established a voluntary Distributed Energy Resource Program in South Carolina. This legislation allows participating utilities to recover costs associated with meeting a 2021 target of 2% aggregate generation capacity from renewable energy sources (S.B. 1189 of 2014, South Carolina General Assembly). Facilities between 1 MW and 10 MW account for half the target; facilities under 1 MW account for the other half. This is a regulatory framework for utilities, not a direct consumer rebate program. Its relevance to heat pump buyers is indirect: it influences how utilities invest in distributed and renewable generation, which can affect future program offerings.

Federal Tax Credits for Heat Pump Installations (Stackable with SC Programs)

The IRS §25C Energy Efficient Home Improvement Credit is the most reliable incentive available to every South Carolina homeowner, regardless of their utility provider.

How the Credit Works

You can claim 30% of the cost of qualifying heat pump equipment and installation, up to a $2,000 annual cap for heat pumps (IRS §25C, Internal Revenue Code). The credit resets each tax year, allowing you to claim it again if you spread upgrades across multiple years. File using IRS Form 5695.

Qualifying Equipment

• Air-source heat pumps meeting CEE Tier or ENERGY STAR Most Efficient standards
• Ground-source (geothermal) heat pumps
• Heat pump water heaters

Your installer should provide an AHRI certificate confirming the equipment meets the required efficiency standards. Without this documentation, your claim could be challenged during an audit.

Separate Caps for Related Upgrades

The $2,000 cap applies specifically to heat pumps. Other improvements have their own caps under §25C:

• Electrical panel or breaker upgrades: up to $600
• Home energy audit: up to $150

These do not reduce your $2,000 heat pump credit. They are separate allowances within the same annual filing.

Stacking with SC Utility Programs

The §25C credit can be combined directly with utility rebates and loans. If Palmetto Electric provides a $1,000 rebate and you spend $8,000 on a geothermal system, you calculate your 30% credit on the full installed cost (consult a tax professional regarding whether the rebate reduces your basis). The federal credit does not coordinate with or reduce your utility rebate.

Recent Updates to South Carolina Heat Pump Incentives

Most South Carolina utility cooperative programs listed here are designated as ongoing with no fixed end date (DSIRE, South Carolina program listings). There has been no significant new state legislation creating residential heat pump rebates since the programs described above were established.

The Inflation Reduction Act expanded and extended IRS §25C, increasing the credit from a lifetime cap of $500 to an annual cap of $2,000 specifically for heat pumps (IRS, updated §25C guidance). This change took effect for tax year 2023 and remains in place.

The IRA also created the HOMES Rebate Program (IRA §50122) and the High-Efficiency Electric Home Rebate (HEAR, IRA §50123), both of which could offer additional point-of-sale rebates for qualifying households. As of this writing, South Carolina's rollout of these programs is not confirmed. Check with the South Carolina Energy Office or DSIRE (dsireusa.org) for the current status before relying on these funds.

Navigating Eligibility and Application for SC Heat Pump Incentives

Step 1: Identify Your Utility Provider

Your eligibility for any cooperative program depends entirely on who provides your electricity. Check your electric bill; the cooperative or municipal utility name will be listed. Cross-reference this with the programs detailed above.

Step 2: Contact the Program Administrator Directly

Program terms can change. Before purchasing equipment, call or email the cooperative's energy services department and ask:

• Is the program currently accepting applications?
• What SEER or efficiency rating does my equipment need?
• Do I need pre-approval before installation?
• What documentation will you require?

Pre-approval requirements vary. Some cooperatives require you to apply before installation; submitting your application afterward can disqualify you.

Step 3: Work with a Licensed HVAC Contractor

South Carolina requires HVAC contractors to hold a license through the South Carolina Contractor's Licensing Board (consult South Carolina Contractor's Licensing Board for current requirements). Beyond licensing, your contractor needs to be knowledgeable about the specific requirements of the rebate or loan program you are pursuing.
