HVAC contractors in Columbia, South Carolina.

Operating as an HVAC contractor in Columbia, South Carolina, requires a multi-layered approach to compliance. You must first secure the appropriate state-level mechanical contractor license through the South Carolina Department of Labor, Licensing and Regulation (LLR). This license serves as your foundational authority to perform HVAC work throughout the state.

Once state-licensed, you must register with the City of Columbia or Richland County to obtain a local business license. Before beginning any specific installation or replacement, you are required to pull a mechanical permit from the local building department. Adhering to these steps, along with maintaining mandatory insurance and EPA refrigerant certifications, ensures your business remains in good standing and avoids costly stop-work orders.
