In order to work as a professional HVAC technician, certain licensing and certifications are required.

  1. EPA Section 608 Certification is required for all professionals working on systems containing refrigerants.
  2. Depending on which U.S. state you plan on working in, you may need special state licensing or certification.
  3. There are additional licensing tests for those who have experience in the field; passing specialized tests may make a candidate more desirable in the job market.

New HVAC technicians should figure out which particular credential type is needed for their career goals.

Three Types of Certification for HVAC Technicians

Why do HVAC techs need certification?

These days, most HVAC systems are so complex that technicians need comprehensive education to develop a true understanding of how they work. This includes training on common problems and the best methods to repair these systems.

Once they’ve completed an HVAC training program, HVAC techs prove their competency in working on HVAC equipment by taking certification and licensing exams.

1. EPA Certifications

EPA Section 608 Certification is required for HVAC technicians who buy or work with any kind of refrigerants.

HVAC technicians must pass an exam specific to one of three specializations in order to become EPA certified:

  • Small appliances
  • High-pressure appliances
  • Low-pressure appliances

They may also earn EPA certification in all types of equipment.

Type I

HVAC technicians who handle small appliances, such as window or room air conditioners, refrigerators, freezers and dehumidifiers, need Type I certification from the EPA. This covers recovery requirements, recovery techniques and safety.[1]

Type II

If new HVAC techs will service high-pressure air conditioning and/or heating units, they need to be certified with this designation. The test for Type II certification covers additional issues related to high- and very-high-pressure appliances, including leak detection, leak repair requirements and refrigeration.

Type III

These certifications are necessary for HVAC techs who work with low-pressure refrigerants, commonly found in chiller units.[2] The Type III certification exam also asks for knowledge regarding:

  • Leak detection
  • Leak repair requirements
  • Recovery techniques
  • Recovery requirements
  • Recharging techniques
  • Refrigeration
  • Safety

Universal

This exam covers low, high and very high-pressure appliances, as well as small appliances. This certification includes Type I, II and III.
