South Carolina Licensing and Efficiency Rules
South Carolina is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in South Carolina the company should carry a state license or registration. Ask for both.
Before You Hire
- Keep two feet clear around the outdoor unit, including snow.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from Columbia Homeowners
What does heat pump repair cost in Columbia?
Most bills land between $170 and $820, including the service call. A typical visit is about $530. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
