How to Start an HVAC Business in North Carolina (Step by Step)

Step 1: Understand NC HVAC Licensing

North Carolina requires all HVAC contractors to be licensed by the NC State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors:

• Website: nclicensing.org
• Phone: (919) 875-3612

The Board issues three heating/cooling contractor licenses:

License	Scope	Fee
H1	Water-based heating systems (boilers, hydronic systems) in any building	$130
H2	Forced air heating and cooling units OVER 15 tons capacity	$130
H3	Forced air heating and cooling units UNDER 15 tons (most residential work)	$130

Most residential HVAC contractors need the H3 license. Contractors doing commercial or large-building work typically need H2. Many full-service HVAC companies obtain multiple license types. Each license costs $130 and renews annually on December 31 for a $150 renewal fee.

Refrigeration work: For commercial, industrial, or transport refrigeration contracting (walk-in coolers, commercial refrigeration systems), a separate license from the NC State Board of Refrigeration Contractors is required.

Step 2: Accumulate Required Work Experience

To qualify for a heating contractor license, you must have:

• 4,000 hours of relevant HVAC work experience obtained while working under a licensed contractor’s supervision
• Up to 2,000 hours may be substituted with academic or technical training directly related to HVAC (accredited HVAC programs, vocational training, military training, etc.)
• Experience must be documented and may be verified by the Board

Step 3: Obtain EPA Section 608 Certification

If your HVAC work involves handling refrigerants (virtually all AC and heat pump work does), you must hold EPA Section 608 certification under the Clean Air Act. This is a federal requirement separate from the NC state license.

• Types: Type I (small appliances), Type II (high-pressure systems), Type III (low-pressure systems), Universal (all types)
• Most HVAC technicians obtain Universal certification
• Obtain from any EPA-approved testing organization (HVAC Excellence, NATE, ESCO Institute, etc.)
• Cost: $20-$100 including study materials and exam
• No expiration once earned

Step 4: Pass the Required Exams

All NC HVAC contractor license applicants must pass two exams:

HVAC Trade Exam:

• Open book; 4-hour time limit
• Covers HVAC systems, codes, load calculations, equipment sizing, and installation practices
• Separate exam for each license type (H1, H2, H3)

Business and Law Exam:

• Open book; 90-minute time limit
• Covers NC contractor licensing law, business practices, contract law, and workplace safety (OSHA)
• Same exam regardless of license type

Exams are administered through PSI Exams. Contact the NC State Board for current exam scheduling and fees.

Study resources: The Board’s website lists approved study materials. HVAC Excellence, NATE, and local community colleges (Rowan-Cabarrus, Wake Tech, Central Piedmont) offer HVAC exam prep courses in NC.

Step 5: Apply for Your License

After passing both exams, submit your application to the NC State Board:

• Completed application form from nclicensing.org
• Proof of work experience (employer letters, records)
• Background check authorization (processed by the Board)
• Exam passing scores (sent automatically by PSI)
• License fee: $130 per license type

Processing time: typically 4-8 weeks after submitting a complete application. Licenses expire December 31 of each year. Renewal fee: $150/year.

Step 6: Form Your Business and Get Insurance

Form an LLC with the NC Secretary of State for $125 online. Essential insurance for NC HVAC contractors:

• General liability insurance — $1-2 million coverage; required by most commercial clients and often required to pull permits
• Commercial auto insurance — Covers service vehicles and equipment in transit
• Workers’ compensation — Required in NC when you have 3+ employees; construction industry: verify requirements as they can differ
• Tools and equipment coverage — Protects your HVAC equipment and tools from theft and damage

Step 7: Pull Permits for Each Job

As a licensed HVAC contractor in NC, you are responsible for pulling the required permits for each job. HVAC installations, replacements, and significant repairs typically require permits from the local building department where the work is being done. Pulling permits requires presenting your NC HVAC contractor license number.

Failing to pull required permits can result in license suspension, fines, and liability for unpermitted work. Always check with the local building department on permit requirements for each specific job.

Frequently Asked Questions

Do I need a license to do HVAC work in North Carolina?

Yes. North Carolina requires all HVAC contractors to be licensed by the NC State Board of Examiners of Plumbing, Heating, and Fire Sprinkler Contractors. The license type depends on the scope of work: H1 for water-based heating systems, H2 for forced-air over 15 tons, H3 for forced-air under 15 tons. Performing HVAC work without a license is illegal and can result in fines and civil liability. The license fee is $130; annual renewal is $150.

How much experience do I need for an NC HVAC license?

You need 4,000 hours of relevant HVAC work experience obtained under a licensed contractor’s supervision. Up to 2,000 hours can be substituted with approved academic or technical training from an accredited HVAC program. This typically works out to 2 years of full-time HVAC work (or 1 year of work + an accredited HVAC program). Document your experience carefully as the Board may request verification.

What exams are required for an NC HVAC contractor license?

Two exams are required: a trade-specific exam (H1, H2, or H3 based on your license type) and a Business and Law exam. Both are open book with time limits (4 hours for the trade exam, 90 minutes for Business and Law). Exams are administered by PSI Exams. Contact the NC State Board at nclicensing.org for current exam scheduling, fees, and approved study materials.

Do I need EPA 608 certification in addition to the NC HVAC license?

Yes. EPA Section 608 certification is required under federal law for any technician who purchases, recovers, or handles refrigerants. This is a separate federal requirement from your NC state contractor license. Most HVAC technicians obtain Universal EPA 608 certification. You can get certified through HVAC Excellence, ESCO Institute, NATE, or other EPA-approved organizations. Cost: $20-$100; no expiration date.

When does an NC HVAC contractor license expire?

All NC heating contractor licenses expire on December 31 of each year, regardless of when you obtained the license. The annual renewal fee is $150 per license type. Renewals can be completed online through the NC State Board’s portal. Operating with an expired license is treated the same as operating without a license – avoid this by setting a calendar reminder for December renewal.

Do I need to pull permits for HVAC work in North Carolina?

Yes, in most cases. HVAC installation, replacement, and significant repairs typically require permits from the local building department. As the licensed contractor, you are responsible for obtaining permits and scheduling inspections. The required permit documents and fees vary by county and city. Always check with the local building department before starting work. Unpermitted HVAC work can create liability issues and problems for homeowners when selling their property.
