North Carolina is said to be one of the best states to work in as a HVAC technician. It offers great chances and salaries to HVAC technicians.

That is why it even attracts engineers from other states, as well as other people who want to work in the HVAC industry.

To be a HVAC technician in North Carolina, you need to acquire a license.

You will have to pass the Refrigeration Contractor Exam. Once you have done that the Refrigeration Contractor License will be awarded to you.

This license will allow you to practice your trade.

This article will provide you with information you need in order to become a HVAC technician in North Carolina.

Heating and Cooling Licensing

In terms of licensing, refrigeration is separated from the hearing and cooling contractors.

There are three types of heating and cooling license: H1, H2, and H3.

H1 – “Wet” or “water-based” comfort heating systems in any building (residential, commercial, industrial).

This type is further divided into classes 1 and 2.

Class 1 license allows you to service any building, and Class 2 is limited to single-family detached dwellings.

H2 – This type allows you to work on air heating and cooling for units of over 15 tons.

H3 – This type is for forced air heating and cooling for units under 15 tons.

It has two classes. Class one can service any building, and class two can only service single-family detached dwellings.

Each of these can have a T designation. T stands for technician.

Technicians are not contractors.

However, they need to be sublicensees of contractors. These groups are: H1-T, H2-T, H3-T.

There is also a possibility of a SGLT designation (SGLT-H1, etc.). This is for employees of state and local governments.

Heating Exams

To be eligible to take a test for any class you need to fulfill the following:

  • You need two years of on-site full-time experience in the in the installation, maintenance, service, or repair of plumbing or heating systems which has to do with the license category you are applying for. It does not matter whether that area of work requires you to have a license or not. This means that you need 4,000 hours of relevant working experience.
  • The academic or technical training can, if you have completed it, add 2,000 hours (30 semester hours) to your experience. The training must be in the field that you want to be licensed in.
  • If you are an applicant who wants to take the technician exam, you need to have 18 months (3,000 hours) on-site full-time experience in the installation, maintenance, service or repair of plumbing or heating systems, which is related to the field you want your license to be in.

It, again, does not matter whether or not a license must be obtained for the work experience you have gained.

Academic or technical training is not mandatory.


Whether you are taking the contractor or the technician license, the examination lasts four hours.

In case you want to be a contractor, you will need to pass an additional business and law exam.

That exam is an hour and a half long.

The materials you need to prepare for your exams can be found on a comprehensive list on the state’s licensing website.

The list is different for each test.

You can find more information about the exam and the application process here.

Eligibility requirements for this exam are as follows:

  • Completed  application form with a non-refundable application fee or examination-license fee

This training needs to have 2000 hours to be accepted as a part of your experience criteria.

If you have practical work, the experience must be acquired while working under the supervision of a licensed refrigeration contractor.

Another case in which the experience will be accepted is if you are a professional engineer, or if you hold relevant experience.
