North Carolina Business and Law examination (unless the Board’s current exemption applies) — question count: confirm with the authority, 90 minutes, passing score: confirm in the current candidate bulletin

Insurance and Bonds

No statewide contractor license surety bond is required for this credential in the cited sources. Project-specific, permit, or public-works bonds may still apply, so confirm bonding before bidding a given job.

The Board’s contractor examination and activation materials do not state a Board-level general-liability minimum. Project owners or local requirements may still require coverage.

Reciprocity

For this classification, North Carolina does not recognize the NASCLA Accredited Examination.

Reciprocal State	Accepted Exam	Conditions
South Carolina	Technical examination waiver only	The current Board packet lists limited South Carolina technical-exam waivers for equivalent heating licenses. The applicant must still meet North Carolina experience requirements, complete the application, and pass the NC business examination.

The Board states that it has no license-reciprocity agreements. Do not treat the limited South Carolina technical-exam waiver as full reciprocity.

Tennessee HVAC License Requirements — Tennessee CMC-C HVAC, Refrigeration and Gas Piping Contractor License
Virginia HVAC License Requirements — Virginia Master HVAC Tradesman License

Step-by-Step Application Roadmap

Choose the proper heating group and class. Group 1 is water-based comfort heating, Group 2 is forced-air heating/cooling over 15 tons, and Group 3 is forced-air heating/cooling of 15 tons or less. Class I and II scopes differ where the Board offers both.
Document 4,000 qualifying hours. Use the Board’s experience forms and supporting employment records. Relevant academic or technical training can count for up to 2,000 hours.
Apply to the Board. Submit the current examination packet, criminal-record documentation, experience evidence, and the $150 application-and-examination fee.
Schedule and pass the PSI examinations. After approval, schedule within the 90-day authorization period. Contractor applicants ordinarily take both the technical and Business and Law parts.
Activate the license promptly. File the activation form and $150 license fee within 45 days of passing. Renew annually to keep the credential active.

Common Filing Mistakes

The following pitfalls summarize the issues most likely to delay, return, or derail a North Carolina HVAC application based on the published board instructions and source materials cited on this page.

Selecting the wrong HVAC group

The Board distinguishes Group 2 systems above 15 tons from Group 3 systems of 15 tons or less; confirm the exact scope before applying or contracting.

Treating EPA certification as a Board-application prerequisite

EPA Section 608 can govern refrigerant work, but it is not listed as an eligibility requirement in the Board’s heating-contractor application materials.

Assuming full reciprocity

The current South Carolina arrangement is a limited technical-exam waiver, not a reciprocal North Carolina license.

Relying on the old $100 exam fee

The Board announced an increase to a $150 application-and-examination fee effective June 1, 2026.

Missing annual renewal

Every license expires December 31; there is no routine CE requirement, but the fee and renewal still must be completed.
