South Carolina HVAC License Financial Requirements

Two Tracks, Two Sets of Financial Rules

South Carolina's HVAC licensing system splits financial requirements between two boards that approach things very differently. The Contractor's Licensing Board (CLB) for commercial work uses tiered financial statements tied to your desired group limit. The Residential Builders Commission (RBC) uses a flat credit check with no CPA involvement and no net worth threshold.

Understanding which financial documents you actually need — and which you don't — can save you thousands of dollars in unnecessary accounting fees and weeks of preparation time.

Commercial Track: CPA Statements and Net Worth

Commercial mechanical contractor applicants must prove their financial capacity to the CLB. You qualify by meeting either a working capital requirement or a net worth requirement for your chosen group:

• Working capital = current assets minus current liabilities
• Net worth = total assets minus total liabilities

The documentation standard escalates with each group:

Groups 1 and 2 accept an owner-prepared financial statement (Doc 172). You fill out the balance sheet yourself, attach a sworn affidavit of accuracy, and submit it. No CPA needed. Group 1 requires $3,500 in working capital or $7,000 in net worth. Group 2 requires $10,000 in working capital or $15,000 in net worth.

Group 3 requires a CPA-compiled balance sheet on a GAAP basis. The CPA organizes your financial data into proper format and includes disclosure notes, but doesn't verify the underlying numbers. Expect to pay $1,500 to $3,000. Group 3 requires $20,000 in working capital or $30,000 in net worth.

Group 4 requires a CPA-reviewed balance sheet on a GAAP basis. The CPA performs analytical procedures and limited verification — a step above compilation. Expect to pay $3,000 to $7,000. Group 4 requires $40,000 in working capital or $60,000 in net worth.

Group 5 requires a CPA-audited balance sheet on a GAAP basis for the initial application. This is the most expensive engagement — the CPA tests transactions, confirms balances with third parties, and issues a formal opinion. Expect to pay $5,000 to $15,000. At renewal, the requirement drops to a CPA-reviewed statement. Group 5 requires $200,000 in working capital or $300,000 in net worth.

If you cannot meet either the working capital or net worth threshold, you can file a surety bond equal to the group's net worth requirement instead of submitting a financial statement at all. That bond option exists at every group level.

Residential Track: Credit Report, No CPA

The RBC takes a fundamentally different approach. There is no net worth threshold, no working capital calculation, and no CPA requirement at any level.

Instead, every residential HVAC specialty (RBH) applicant must submit a complete personal credit report dated within 30 days of the application. The report must come directly from one of the three major bureaus — TransUnion, Experian, or Equifax.

Here's what the RBC is actually looking for: unresolved construction-related judgments, mechanic's liens, or active bankruptcy proceedings. The commission does not enforce a minimum credit score. A lower score without those issues is not automatically disqualifying, while an outstanding construction judgment can be flagged regardless of score.

If your credit report shows blemishes — a past collection, a medical debt, a late payment — the RBC allows you to submit a written explanation letter addressing each item. The board reviews the explanation in context. This isn't an automatic rejection trigger.

Beyond the credit check, the RBC requires a $10,000 surety bond if you'll be performing residential HVAC work exceeding $5,000 per project. Since most residential system installations and change-outs exceed that threshold, the bond is effectively mandatory for active contractors. The bond must be in your individual legal name, not a business entity name.

Common Financial Mistakes That Delay Applications

Submitting an expired credit report. The RBC's 30-day window is strict. If your application sits in your desk drawer for five weeks after you pull the report, you'll need a fresh one. Order the credit report last, right before you submit the full application package.

Using owner-prepared statements for Group 3 or higher. The CLB will reject a Doc 172 for anything above Group 2. If you're reaching for Group 3, budget the time and money for a CPA-compiled statement before you start the application.

Filing the financial statement on a tax basis instead of GAAP. CPA-prepared statements for the CLB must use Generally Accepted Accounting Principles (GAAP) format, not a tax-basis or cash-basis presentation. Make sure your accountant knows the CLB's requirement before they begin the engagement.

Getting the bond name wrong. Commercial bonds go in the business entity name; residential bonds go in the individual's legal name. A mismatch causes an immediate rejection.

Planning Your Financial Timeline

CPA engagements take time. A compiled statement might be ready in 2 weeks if your bookkeeping is clean. A reviewed statement takes 3 to 5 weeks. A full audit can take 6 to 12 weeks depending on the complexity of your books and the CPA's availability.

Build this timeline into your licensing plan. If you need an audited statement for a Group 5 application and your fiscal year just ended, you're looking at a minimum 2-month head start before you can even submit to the CLB.
