What Do HVAC Certifications Mean?

March 25, 2022

When you’re searching for quality HVAC services, you likely want a technician that understands what they’re doing. Many service companies advertise experienced staff, but how can you know for sure? One of the easiest ways to verify if an HVAC technician is knowledgeable is by checking their certifications. HVAC certifications can demonstrate proficiency in services like air conditioning repair, installation and maintenance services as well as other key aspects of the industry.

There are a variety of HVAC certifications available. Some concentrate on a core body of knowledge technicians should have, while others are a result of industry standards for energy efficiency and sustainability. We’ll compare key details about a few of the most common HVAC certifications you’ll find in your search for services.

NATE

The North American Technician Excellence certification is the largest program for HVAC proficiency, with tens of thousands of certified technicians. Other organizations like the ACCA and the federal Environmental Protection Agency cooperate with the NATE program to standardize the certification testing. To pass, participants must achieve a minimum score of 70%. To maintain NATE certification, technicians must receive continuing education or take another exam every two years.

Total certification is a multiyear process consisting of four separate tests. The first two are designed for entry-level technicians while the second set of exams provide full certification and senior-level status:

  1. Ready-to-Work Certificate – This certificate provides core knowledge and skill sets that can supplement any education or training already completed. The Ready-to-Work certification is particularly beneficial for recent graduates of trades programs.
  2. HVAC Support Technician Certificate – After 6 to 12 months of experience, this exam is offered to teach fundamental topics concerning full NATE certification.
  3. Core and Specialty Certification – Once a technician has been in service for two or more years, they can be tested for full NATE certification. Technicians will have to pass both the core exam as well as a specialty exam for installation or servicing specific types of HVAC products.
  4. Senior-Level Efficiency Analyst Certification – Senior status is the highest NATE certification offered. Technicians need to be certified in two specialty services—one in heating and one in air conditioning—to be eligible for applying for the senior certificate.

ASHRAE

The American Society of Heating, Refrigerating and Air Conditioning Engineers was founded in 1894. ASHRAE and its members offer research and education about HVAC systems with the intent to encourage sustainability, energy efficiency and high indoor air quality. Through their efforts, ASHRAE creates industry standards with federal recognition. These standards apply not only to HVAC equipment, but to the buildings themselves as well as their other systems.

Many of ASHRAE standards are focused on commercial properties and industrial facilities, as they typically have the highest rates of energy expenditure. They’ll study how HVAC system design can be improved as well as how equipment should be installed and serviced. ASHRAE also studies how the engineering and architectural design of the building itself impacts energy use.

ACCA

Another national HVAC accreditation organization, the ACCA stands for Air Conditioning Contractors of America. This organization encourages rigorous training and conducts sessions for technicians to attend both on-site and online. Contractors looking for accreditation have two programs to select from:

  • The Existing Homes Program for Residential Service and Installation (RSI): This track ensures technicians can install, replace and maintain HVAC equipment common in residential properties such as homes and apartments.
  • The New Homes Program: The New Homes track prioritizes designing and installing HVAC systems with ENERGY STAR®-certified equipment for qualifying homes. Random audits are completed to ensure members maintain their expertise.

ICE

Industry Competency Exams are handled by NATE to make sure technicians meet industry standards for entry-level (one year or less) experience. These are distinguished from the NATE certification exams but review similar topics. Testing is available for residential HVAC equipment as well as light commercial heating and cooling. Separate tests are also available for commercial refrigeration.

To be ICE-certified for residential equipment, technicians will need to pass both a core exam as well as specialty courses for services like furnace installation, service or even knowledge of components. Commercial ICE certifications don’t include the core exam and will review all relevant knowledge instead of specialty sections.

EPA Section 608

The Environmental Protection Agency provides comprehensive regulations within the HVAC industry. One of the most well-known sets of regulations is the federal Clean Air Act. Under Section 608 of the Clean Air Act, the EPA requires technicians who handle equipment capable of releasing refrigerants to pass a certification test. To earn the Section 608 Technician Certification, the test will be specific to the systems the technician works with and administered by an approved organization.

HVAC Excellence

The HVAC Excellence Certifications of Achievement cover a broad range of competency tests for varying levels of proficiency in the HVAC industry. For example, the Heating, Electrical, Air Conditioning Technology (H.E.A.T.) + student outcome assessments are offered for high school students who have completed qualifying HVAC education programs. Other testing is available for those seeking employment as well as for experienced technicians seeking Professional or Master Specialist accreditation.
