A heating, ventilation, and air conditioning (HVAC) technician or contractor keeps you warm in the winter and cool in the summer—and in North Carolina, where winter temps dip into the 20s and summer soars into the 90s, their job is important.
To work as an HVAC technician or contractor in North Carolina, you must be licensed. To obtain your license, you’ll need to gain experience and pass an exam. HVAC technicians and contractors install, maintain, and repair heating and cooling systems along with the ventilation systems for both.
HVAC workers work with wet and forced air systems and are licensed in North Carolina by groups depending on the type and size of HVAC systems: Heating Groups 1 (H1), 2 (H2), and 3 (H3). Within each group, there are two classes. Class I allows you to work on systems in residential, commercial, and industrial buildings, and Class II is for residential only.
Here is all the information you need to get started in a rewarding career as a Licensed HVAC technician or contractor in North Carolina.
Education and Training Requirements
Those who excel as HVAC technicians and contractors like to work in varied environments. They’re excellent problem solvers and have a mechanical aptitude. HVAC contractors work with different people, whether those are homeowners, general contractors, or subcontractors.
To apply to take the Plumbing, Heating Group No. 1, Heating Group No. 2 and/or Heating Group No. 3 Contractor or Technician exam and get your license, you must meet certain experience and education requirements for the technician or contractor license.
Education Requirements
Your first step is to earn a formal HVAC diploma or attend a certificate program, or you can earn your two-year Associate’s degree. You can also fulfill this requirement with a formal apprenticeship with a local union or trade organization, or through an informal apprenticeship with a sponsoring employer as an entry-level employee supervised by a licensed contractor.
HVAC Technician License
Full-time, on-the-job experience in installation, maintenance, service or repair of heating and cooling systems related to the license category include:
-
Class I: 18 months or 3,000 hours
-
Class II: 15 months or 2,500 hours
HVAC Contractor License
To become a licensed contractor, you also need direct, hands-on experience specific to the license you want. All contractors for all groups and classes must have two (2) years or 4,000 hours of documented experience. Up to half of the requirement (2,000 hours) can come from an academic or technical training college directly related to the field (45 quarter hours or 30 semester hours)
Benefits of Formal Training
HVAC systems are complex with a lot of moving parts. For that reason, many employers prefer to hire HVAC licensees who have some formal training from a vocational or technical school along with on-the-job experience. Apprenticeship programs offer a chance to earn while you learn and include field experience and education. Your apprenticeship will also count toward the required hours to obtain your HVAC technician or contractor license.
Certificate programs take three to six months to complete. An associate degree takes two years, and a bachelor’s degree takes four years. Apprenticeship programs can take three to four years, but they meet the full experience requirement so that you can take the exam.
EPA Certification Requirement
The EPA Section 608 certification is required for anyone who handles refrigerants, whether that is installing, maintaining, or disposing of equipment. Apprentices are exempt from this; however, licensed technicians and contractors are required to pass an EPA-approved test.
The EPA defines technician [or contractor] as anyone who:
-
Attaches and detaches hoses and gauges to and from an appliance to measure pressure within the appliance.
-
Adds refrigerant to or removes refrigerant from an appliance.
-
Any other activity that violates the integrity of a motor vehicle air conditioner (MVAC)-like appliance or small appliance (other than disposal).
Licensing Requirements for HVAC Technicians in NC
Once you meet eligibility requirements to take the exam, the next step is to apply for the Plumbing, Heating Group No. 1, Heating Group No. 2 and/or Heating Group No. 3 Contractor or Technician exam. It can take 4-6 weeks to be approved.
Following approval, you have 90 days to take the exam and 45 days after passing the exam to activate your license.
