What Do HVAC Certifications Mean?

March 25, 2022

When you’re looking for quality HVAC services, you likely want a technician that knows what they’re doing. Many service companies advertise expert staff, but how can you know for sure? One of the most consistent ways to verify if an HVAC technician has experience is by looking for their certifications. HVAC certifications can demonstrate proficiency in services like air conditioning repair, installation and maintenance services as well as other important aspects of the industry.

There are a variety of HVAC certifications available. Some prioritize a core body of knowledge professionals should have, while others are a result of industry standards for energy efficiency and sustainability. We’ll review key details about some of the most common HVAC certifications you’ll see 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 tests. To pass, participants must achieve a minimum score of 70%. To maintain NATE certification, technicians must receive additional education or retake an exam every two years.

Complete certification is a multiyear process made up of four separate tests. The first two are designed for entry-level technicians while the final set of exams provide full certification including senior-level status:

  1. Ready-to-Work Certificate – This certificate provides core knowledge and skill sets that can reaffirm 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 test proficiency on fundamental topics concerning full NATE certification.
  3. Core and Specialty Certification – After a technician has been in service for two or more years, they can be tested for full NATE certification. Technicians will need 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 available. Technicians have to be certified in two specialty services—one in heating and the other in air conditioning—to be eligible for applying for the senior certificate.

ASHRAE

The American Society of Heating, Refrigerating and Air Conditioning Engineers was created in 1894. ASHRAE and its members offer research and education about HVAC products with the intent to encourage sustainability, energy efficiency and healthy indoor air quality. Through their efforts, ASHRAE creates industry standards with federal recognition. These standards are applicable 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 often 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 maintained. ASHRAE also monitors how the engineering and architectural design of the building itself influences energy use.

ACCA

Another nationwide HVAC accreditation organization, the ACCA stands for Air Conditioning Contractors of America. This organization encourages rigorous training and facilitates sessions for technicians to complete both on-site and online. Contractors hoping 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 found in residential properties such as homes and apartments.
  • The New Homes Program: The New Homes track focuses on designing and installing HVAC systems with ENERGY STAR®-certified equipment for qualifying homes. Random audits are completed to ensure members maintain their proficiency.

ICE

Industry Competency Exams are offered by NATE to make sure technicians meet industry standards for entry-level (one year or less) experience. These are separate from the NATE certification exams but encompass similar topics. Testing is offered for residential HVAC equipment as well as light commercial heating and cooling. Separate tests are even 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 cover all relevant knowledge instead of specialty sections.

EPA Section 608

The Environmental Protection Agency provides substantial regulations for 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 work with equipment capable of releasing refrigerants to pass a certification test. To earn the Section 608 Technician Certification, the test should be specific to the products the technician works with and administered by an approved organization.

HVAC Excellence

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

The Benefits of Certified HVAC Technicians

When you receive service from technicians who are certified by organizations like NATE, ASHRAE and the ACCA, you’re giving your HVAC system a higher standard of service. Benefits of hiring certified HVAC technicians include:

Demonstrates proficiency and dedication: Technicians who are dedicated to their customers’ sense of comfort will seek out certifications to demonstrate their expertise. When you see a service company in Wharton offering NATE- or ICE-certified staff, you’ll know they go the extra mile to improve their services such as air conditioning installation.

Can help reduce costs and speed up services: Professionals who devote the time and resources required for these certifications often require less time and fewer resources when servicing your equipment. Not only can things like furnace repair, maintenance and installation proceed more quickly, but the faster progress can also reduce labor expenses.
