What is an HVAC Certification?

An HVAC Certification validates that an individual is trained enough in the basics of heating, air conditioning, and ventilation. Though obtaining a certification is not required at the federal level, it’s still required by some states. 

However, EPA has made its certification necessary for an individual who deals with refrigerants. If you’re working with refrigerants, you need to have the Section 608 certification issued by EPA. (More on that later)

Here are the top institutions that issue certifications for HVAC Techs –

  • Environmental Protection Agency (EPA)
  • North American Technical Excellence (NATE)
  • ESCO Group
  • Refrigeration Service Engineers Society (RSES)
  • Refrigerating Engineers and Technicians Association (RETA)

Top Benefits of an HVAC Certification

There are some benefits and perks of being a Certified HVAC Technician, let us take a look at some of them:-

An advanced understanding of HVAC Systems

HVAC Certification Boards and Requirements

Each authority has its own rules. For instance, for some certifications, students may be required to have completed a training course, while for others, working experience provides sufficient knowledge to pass an exam.

Some certifications might have a written test, while some might require a hands-on demonstration of skills.

Here are Some common organizations that issue certifications are as follows:


ASHRAE offers seven certifications as of March 2022, as follows:

  • BCxP – Building Commissioning Professional Certification
  • BEAP – Building Energy Assessment Professional Certification
  • BEMP – Building Energy Modeling Professional Certification
  • CHD – Certified HVAC Designer
  • HBDP – High-Performance Building Design Professional Certification
  • HFDP – Healthcare Facility Design Professional Certification
  • OPMP – Operations and Performance Management Professional Certification

HVAC Excellence

There are several certifications for both students and high school students as well, let’s have a look at them below:-

  • For High School Students- Students who are enrolled in HVAC programs at high schools can earn two certifications: technology for heating, electrical, and air conditioning (H.E.A.T.) and H.E.A.T. Plus.

    The first is a 100-question test that measures the students’ familiarity with common HVAC topics like electrical theory, fundamental motors and capacitors, and AC troubleshooting. 
  • Employment Ready Certifications- Other HVAC Excellence offerings are ideal for students enrolled in vocational programs or trade schools and include employment-ready certifications for entry-level employees.

    An exam ranging from 50 to 100 questions is required for each topic.
  • Specialty Certifications- Additionally, HVAC Excellence offers specialty certifications that demonstrate a candidate’s proficiency in highly specialized areas like R-410A refrigerant system use, residential heat load analysis, and environmental awareness.
  • Professional Technician Certifications- Moreover, HVAC Excellence gives moderate proficient level professional certifications to those with around two years of verified work experience in a particular field (e.g., heat pump service, combustion analysis, residential air conditioning).

    These certifications all require a test. Master specialist hands-on technician certifications require at least three years of verified work and a demonstration of skills for those with even more experience. (Also see: HVAC service technician)
  • Educators Credentials- Lastly, there are various educator credentials, such as the certified subject matter educator (CSME) for HVAC instructors, which demonstrates a field professional’s ability to instruct in a variety of subject areas, including oil heat, heat pumps, air conditioning, and others.

    Because it requires passing six CSME subject exams with a score of at least 80% and completing a capstone project, the certified master HVAC-R educator (CMHE) credential is ideal for multi-area specialists who want to teach.

EPA Certification

Those who work with refrigeration systems or refrigerants are required by the EPA to obtain a Section 608 certification, as previously stated. There are three types:

  • Type I certifications for small appliances.
  • Type II for appliances with high pressures.
  • Type III for appliances with low pressure.


North American Professional Greatness (NATE) offers an extensive variety of specialty confirmations at different levels.

To become certified by NATE, prospective HVAC technicians must pass a core exam and a specialty exam. The specialty tests are partitioned into installation and service:

  • Specialties in the installation: Air conditioning, air distribution, heat pumps (air-to-air), and gas heating are the five installation specialties.
  • Service Specialties: Air conditioning, air distribution, oil heating (air), gas heating (air), heat pump (air-to-air), Hydronics gas, Hydronics oil, commercial refrigeration, light commercial refrigeration, and senior-level efficiency analyst are among the various service specialties, many of which are offered in Spanish.

    NATE also provides certifications for ground source heat pump installers and HVAC performance verifiers, Section 608 certification, and the industry competency exams (ICE), which cover a variety of residential and commercial HVAC systems and related skills.


Industrial refrigeration technicians can earn a variety of certifications through the Refrigerating Engineers and Technicians Association (RETA).

HVAC Certification Vs License

In the HVAC industry, the terms “certification” and “licensing” are frequently used interchangeably. However, it is essential to know the difference between the two.

HVAC Certifications are mostly voluntary, such as NATE, which exhibits your ability in the field.

HVAC technician license, on the other hand, then again, are issued by the state or city you intend to work in. Most licenses are issued by the state or city for HVAC Contractors.

Should You Get Certified? 

You will most likely need to obtain your EPA 608 certification if you intend to work as an HVAC technician.

In case you are signed up for an HVAC Technician apprenticeship program and you are managed by a certified technician, you might be excluded from the EPA 608 certification requirement.

While NATE and HVAC Excellence certifications are optional, they can help you advance in your HVAC career by demonstrating to employers that you are competent and committed to learning the trade.

How To Get an HVAC Certification

There are a few steps to get HVAC Certified:-

  • Earning a high school degree or GED

HVAC training programs typically require a high school diploma or GED. Courses in computer science, physics, and environmental science can all help you prepare for a career in heating and cooling.

Some colleges have programs for high school students to earn industry credentials, and some high schools provide vocational training.

  • Participating in HVAC training

One way of getting certified as an HVAC technician is to complete HVAC Training.
