The HVAC Certification Process Explained

High school diploma

Getting a high-school diploma is the first step you should take in pursuing a career as an HVAC technician. Make sure you take an interest in mathematics and physics subjects so that your fundamentals are strong.

HVAC Training

Like any profession, it is important to have a solid base in HVAC-related subjects through classroom training. The ideal way to learn the trade is by completing an accredited HVAC program from a community college, trade school, or vocational college.

HVAC Apprenticeship

Local associations like the Air Conditioning Contractors of America and the Associated Builders and Contractors run HVAC apprenticeship programs that typically last three to five years.

Practical Experience

Most certifications require you to have a bare minimum of 12 months of practical experience, so working under an HVAC contractor to acquire on-the-job training is necessary.

Additional Certifications

Agencies like the North American Technical Excellence (NATE), HVAC Excellence, Refrigeration Service Engineers Society (RSES), and Refrigeration Engineers and Technicians Association (RETA) offer additional specialty certifications.

Types of HVAC Certificates

The primary types of certifications for HVAC technicians include the EPA Section 608 Technician Certification and the industry organization certifications. The Section 608 Refrigerant Recycling Rule requires technicians performing service, maintenance, or disposal of equipment that releases refrigerants and substitute refrigerants to get an HVAC license.

This lifelong certification requires you to pass an EPA test conducted by an EPA-approved organization.

EPA Certifications

The Environmental Protection Agency (EPA) mandates all HVAC technicians who work with refrigerants to acquire the Section 608 Technician Certification. Under EPA certifications, there are four types:

  • Type I Certification: Small appliances (air conditioners, domestic refrigerators, and vending machines)
  • Type II Certification: High-pressure appliances (residential air conditioners, refrigeration units, and heat pumps)
  • Type III Certification: Low-pressure appliances (chillers, etc.)
  • Type IV Certification: Universal (which includes all the equipment mentioned above)

Any HVAC technician who works with refrigerants must pass a written exam in one or more of these types.

NATE Certification

The North American Technical Excellence or NATE certification ensures that you are adequately trained to perform an HVAC technician’s duties. This type of certification may include:

  • Installation tests
  • Servicing tests
  • Specialty parts
  • Refrigerants
  • Core units

HVAC Certification Requirements

As mentioned above, an HVAC technician’s requirement to have a valid HVAC certification may be mandatory in some states or regions. The laws around having an HVAC certification depend on the state in question.

In some cases, you may have to complete an HVAC program from an accredited trade school, while in some others, you must have a few years of work experience. To get the certification, you are also expected to pass an exam covering local electrical codes and general HVAC subjects.

HVAC Licensing Requirements by State

The licensing requirements for HVAC technicians differ from state to state.

States like Illinois, Colorado, Kansas, Indiana, Missouri, Arizona, New York, Vermont, and Wyoming are examples of regions that don’t require state-wide licensing. Almost every other state requires technicians to have an HVAC certification.

In states that need licensing, candidates must pass a written exam. The basic requirements for HVAC licensing in Texas, for example, are for you to pass the NATE exam and register with the state government.

Delaware offers HVACR Technician licensure that follows the traditional apprentice, journeyperson, master licensing model. In Alaska, on the other hand, you must hold separate electrical and plumbing licenses.

The terms, conditions, exams, or mandates in other states may vary. Refer to this state-wise guide to licensing laws for more details.

Even if you live in an area where you don’t need an HVAC certification to ply your trade, it is always better to have solid credentials.

What is a master HVAC license?

A master HVAC license serves as the highest level of a technician in the HVAC business in some states. Someone with a master HVAC license can be the contractor himself. If you have a master HVAC license, you are generally considered to be better than a journeyman (in terms of wage, experience, and expertise).

Master HVAC technicians repair and maintain HVAC equipment, manage the installation and repair, and ensure that the work follows the state building codes. Although the state-wise requirements vary, you need at least one year of work experience as a journeyman to be eligible for the state’s master’s examination in most cases.

What is an HVAC engineer? Does an HVAC engineer require certification?

An HVAC engineer is a professional who designs heating, ventilation, and air conditioning systems or accessories. As an HVAC engineer, you need to find solutions to everyday HVAC problems, work in labs with other engineers, or partner with architects to assess residential or commercial spaces’ right systems.

An HVAC engineer is generally required to have a bachelor’s degree in engineering and HVAC certification in some states.

What states do not require an HVAC license?

States like (but not limited to) Wyoming, Vermont, Illinois, Arizona, New York, Colorado, Kansas, Missouri, and Indiana don’t require technicians to have an HVAC license.
