South Carolina CAGC Trades Certification

What Changed in 2026

Effective January 1, 2026, the Carolinas Associated General Contractors (Carolinas AGC, commonly called CAGC) took over full administrative control of the South Carolina Mechanical Trades Certification Program from the Municipal Association of South Carolina (MASC). If you've been searching for "MASC trades certification" and hitting dead ends, this is why — the program still exists, but it now operates under CAGC with new branding, a new administrative office, and updated certification cards.

The actual exams and reference materials haven't changed. PROV (formerly ProV) remains the designated testing administrator, so the technical exam structures and questions are the same ones MASC used. What changed is who manages the database, issues certification cards, and handles biennial renewals.

What CAGC Trades Certification Actually Is

The CAGC SC Trades Certification is a voluntary professional credential — it is not a state contractor license. It proves technical competency in a specific mechanical trade, but it does not by itself authorize you to contract for projects, pull permits, or operate an HVAC business in South Carolina.

Where it becomes valuable is at the licensing stage. The Contractor's Licensing Board and the Residential Builders Commission both recognize CAGC trades certifications as a pathway to satisfy or waive technical exam requirements when applying for a state-level mechanical or residential specialty license. In practice, this means a CAGC-certified technician may skip the state's technical trade exam (administered by PSI) and proceed directly to the Business Management and Law exam.

The most relevant CAGC certification for HVAC professionals is the HARV (Master Mechanical) credential. HARV covers heating, air conditioning, refrigeration, and ventilation — the full spectrum of mechanical trade work. Other certifications in the program cover specific trades like plumbing, electrical, and gas.

How to Get CAGC Certified

The process follows these steps:

1. Verify eligibility — CAGC certifications typically require documented trade experience, though the specific hour and year requirements vary by certification level. Contact CAGC directly or check their current candidate bulletin for the HARV credential requirements.

2. Register for the PROV exam — Technical exams are administered through PROV at regional testing centers. The exams are open-book, but you can only use the specific reference texts listed in the candidate information bulletin.

3. Pass the technical exam — Passing scores and question counts vary by trade classification. The exam tests practical knowledge of code compliance, installation standards, and safety requirements.

4. Receive your CAGC certification card — Once you pass, CAGC issues your trades certification card with an expiration date. The card is valid for two years and must be renewed biennially through CAGC.

Using CAGC Certification for State Licensing

This is the practical payoff. When you apply for a commercial mechanical contractor license through the CLB or a residential specialty HVAC (RBH) license through the RBC, your CAGC trades certification can substitute for the state's PSI technical trade exam.

The exam waiver only applies to the technical portion. You must still pass the South Carolina Business Management and Law exam administered by PSI — that requirement has no waiver pathway regardless of certifications held.

The sequence matters: get your CAGC certification, then use it as documentation when filing your state license application. Include a copy of your current, unexpired CAGC certification card in your application package along with your PSI Business and Law exam pass sheet.

Legacy MASC Cards

If you hold an existing MASC-issued trades certification card, it remains valid until its printed expiration date. You don't need to re-test or re-apply through CAGC while the card is current.

When your MASC card expires, your renewal goes through CAGC — not MASC. CAGC now handles the biennial renewal through its updated system. New applications, exam scheduling through PROV, and verification letters must all go through the CAGC SC Trades Certification program.

If a municipal building department or licensing board requests verification of your trades certification, that verification now comes from CAGC. MASC no longer maintains the active certification database.

CAGC Certification vs. State License: The Distinction

This is the point that causes the most confusion. A CAGC trades certification proves you know how to do the work. A state license from the CLB or RBC proves you have the legal authority to contract for the work, hire employees, pull permits, and operate a business.

You need the state license to operate independently. CAGC certification is optional, but it can streamline the licensing process (by waiving one exam) and cannot replace the license itself.
