What to confirm before scheduling insulation work
What insulation rebates are available in South Carolina?
South Carolina homeowners can access insulation rebates through Santee Cooper EmpowerHome (Santee Cooper (Berkeley/Horry/Georgetown counties)). Insulation rebates are available — check current program. Air sealing rebates are available — check current program. Rebates typically cover attic insulation to R-49 or higher, basement wall insulation, and sometimes floor/crawlspace insulation. A home energy assessment is usually required first. Exact amounts depend on your utility and current program rules.
How much insulation do I need to qualify for the South Carolina rebate?
Most South Carolina insulation rebate programs through Santee Cooper EmpowerHome require adding insulation to bring your home up to current code standards (typically R-38 to R-60 in the attic depending on climate zone). If your existing insulation is already at R-38 or higher, you may not qualify for the attic insulation rebate. A home energy assessment through Santee Cooper EmpowerHome will confirm exactly what improvements qualify in your home.
Does South Carolina require insulation before a heat pump rebate?
Many South Carolina heat pump rebate programs through Santee Cooper EmpowerHome recommend or require weatherization (including insulation and air sealing) before approving a whole-home heat pump rebate. This is not a penalty — a well-insulated home needs a smaller heat pump system, has lower operating costs, and qualifies for the full rebate tier. Check with Santee Cooper (Berkeley/Horry/Georgetown counties) for current requirements specific to your upgrade path.
Can I combine the South Carolina insulation rebate with the federal tax credit?
Yes. The federal 25C Energy Efficient Home Improvement Credit covers 30% of insulation and air sealing costs up to $1,200 per year — completely separate from Santee Cooper EmpowerHome utility rebates. Stack both: apply for the Santee Cooper EmpowerHome rebate after installation, and claim the 25C credit on your tax return for the same year. Note: the 25C credit for insulation requires the insulation to primarily reduce heat loss/gain (decorative materials don't qualify).
