HVAC certification is proof that a technician or engineer is a highly skilled and trustworthy professional. In a trade necessary for safe, temperature-controlled air distribution, HVAC technicians are likely to stay in demand for the foreseeable future, and certification ensures you can take advantage of this demand.

Did you know that the U.S. identified HVAC as one of the few sectors declared "essential" during the height of the global pandemic? Indoor air quality, vaccine distribution and storage, virus containment, and data center temperature control all fall under the umbrella of the HVAC profession. So, this profession is a smart choice for someone who wants job stability. Plus, there's good money to be made as a skilled and certified HVAC technician.

HVAC (an acronym for heating, ventilation, and air conditioning) requires a high school diploma, technical education, and certification. If you're interested in learning how to install furnaces, air conditioning systems, heat pumps, and more, a career in HVAC can offer rewarding work in changing environments, a steady flow of good income, and job security. The U.S. Bureau of Labor Statistics predicts a growth rate of 6 percent for HVAC technician jobs and more than 37,000 job openings each year through 2032.*

Why get HVAC certification?

Certification indicates training beyond the basics in any profession. Getting certified in a particular area shows a third-party organization tested the knowledge and skills of the professional and attests to their achievements.

HVAC certification offers a seal of approval indicating the tech knows what they are doing. So, getting certified allows you to be more competitive in an already tough job market, show your competence, and indicate you meet internationally agreed-upon standards in the field.

Which HVAC certification is best?

There are several different certifications available in the HVAC industry. Some are more general in nature, and some are highly specialized. Choosing the right one for you will come down to what types of specialization or training you want to pursue.

NATE HVAC Certification

NATE is a coalition between the U.S. Environmental Protection Agency (EPA) and the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE). NATE certification is the most common HVAC certificate and one of the most well-respected certifications for HVAC professionals.

To qualify for NATE HVAC certification, techs must pass a test showing their knowledge of general HVAC topics, as well as a minimum of one specialized test about installation or service, such as air conditioning systems, gas or oil heating, and HVAC system efficiency. NATE requires its certified techs to have follow-up training and testing every two years. Technology changes rapidly, and NATE wants its technicians to stay relevant.

NATE offers three levels of HVAC certification:

  • Heating & Cooling Support, designed for techs with six months to one year's experience
  • Professional Level, requiring two years of professional experience
  • Senior Level Efficiency Analyst, for those with five or more years of experience

ASHRAE HVAC Certification

ASHRAE, founded in 1894, boasts more than 50,000 members worldwide. ASHRAE also offers stand-alone HVAC certifications outside of its alliance with NATE. These specialized certifications include:

  • 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

ASHRAE's HVAC certifications are approved by the American National Standards Institute (ANSI). ANSI is a non-profit organization coordinating and administering U.S. voluntary standards and conformity assessments.

Refrigeration Service Engineers Society Certification

RSES offers specialized HVAC certifications, including EPA Section 608, commercial air conditioning, commercial refrigeration, heating, and HVAC-R (refrigeration) electrical.

EPA HVAC Certifications

The U.S. Environmental Protection Agency (EPA) requires certifications for HVAC techs working with refrigerants. There are three levels of HVAC certification from the EPA:

  • Type I—EPA Section 608 certification for techs working on stationary HVAC equipment
  • Type II—EPA Section 609 certification for techs working on automotive air conditioning
  • Type III—EPA Section 608 certification for techs working on equipment using a low-pressure refrigerant
  • Universal—Anyone holding all three of these EPA certifications

Only techs with EPA HVAC certifications can legally buy, use, handle, and dispose of refrigerants.

Refrigerating Engineers and Technicians Association (RETA)

If you're seeking certification in industrial refrigeration, check out RETA. Their specialized HVAC certifications include:

  • CARO—Certified Assistant Refrigeration Operator for entry-level workers
  • CIRO—Certified Industrial Refrigeration Operator
  • CRST—Certified Refrigeration Service Technician
  • CRES—Certified Refrigeration Energy Specialist
  • RAI—RETA Authorized Instructor

HVAC Excellence Certification

HVAC Excellence was founded in 1994 to ensure HVAC technicians are competent and meet ongoing standards. This certification is offered by The ESCO Group, an organization devoted to training and certifying HVAC pros. ESCO claims to offer "stackable" certifications designed to meet the educational and training needs throughout an entire career. These HVAC certifications include:

  • Student Outcome Assessments for high school students completing HVAC training
  • EPA Section 608 and 609 Certifications
  • Employment Ready Certification for new techs not yet fully certified in HVAC Excellence
  • Professional Level Certifications for techs with two or more years of experience
  • Master Specialist Certifications for those with three or more years of experience
  • Specialty Certifications ranging in topics from resident heat load analysis to green awareness to conducting residential heat analyses

HVAC Excellence also offers credentialing for HVAC pros transitioning into teaching or proctoring test results.

ACCA's HVAC Quality Installation Standard

The Air Conditioning Contractors of America (ACCA) is a national trade association serving the HVAC industry. They administer the HVAC Quality Installation (QI) standard, which can be earned in residential or light commercial HVAC design. Some of the skills tested include the use of HVAC-specific software, load calculations, and duct design.

State and local licensing

Depending on where you live, you may have to be licensed by your state and sometimes county or municipality. These licenses certify a tech is qualified to practice HVAC professionally and safely.

The following states do not require licensing:

  • Arizona
  • Colorado
  • Kansas
  • Indiana
  • Missouri
  • New York
  • Vermont
  • Wyoming

While these states don't require HVAC techs to be licensed, most cities and counties in those states do.

It's a safe assumption that if you don't reside in one of the above states, you'll need both a state and a local license, and you will likely need to take licensing exams.
