When you’re searching for quality HVAC services, you probably want a technician that knows what they’re doing. Many service companies advertise experienced staff, but how can you know for sure? One of the most consistent ways to check if an HVAC technician has experience is by checking 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 multiple HVAC certifications available. Some prioritize a core body of knowledge technicians 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 find in your search for services.
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, participating technicians must achieve a minimum score of 70%. To maintain NATE certification, technicians must receive additional 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 other set of exams provide full certification and senior-level status:
- 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.
- HVAC Support Technician Certificate – After 6 to 12 months of experience, this exam is offered to test proficiency on fundamental topics relevant to full NATE certification.
- Core and Specialty Certification – After a technician has been in service for two or more years, they can receive NATE certification. Participants will have to pass both the core exam as well as a specialty exam for installation or servicing specific kinds of HVAC equipment.
- Senior-Level Efficiency Analyst Certification – Senior status is the highest NATE certification available. Technicians need to be certified in two specialty services—one in heating and one in air conditioning—to be eligible to apply for the senior certificate.
The American Society of Heating, Refrigerating and Air Conditioning Engineers was founded in 1894. ASHRAE and its members share research and education about HVAC equipment 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 research how HVAC system design can be improved as well as how equipment should be installed and serviced. ASHRAE also monitors how the engineering and architectural design of the building itself influences energy use.
Another nationwide HVAC accreditation organization, the ACCA stands for Air Conditioning Contractors of America. This organization promotes rigorous training and offers sessions for technicians to attend both on-site and online. Contractors wanting accreditation have two programs to pick 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 like 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 conducted to ensure members maintain their expertise.
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 cover similar topics. Testing is offered 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 have 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 in-depth 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 handle equipment capable of releasing refrigerants to pass a certification test. To earn the Section 608 Technician Certification, the test should be specific to the equipment the technician works with and administered by an approved organization.
The HVAC Excellence Certifications of Achievement encompass a broad 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. Additional testing is available for those seeking employment as well as for experienced technicians seeking 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 better standard of service. Benefits of hiring certified HVAC technicians include:
Demonstrates proficiency and dedication: Technicians who are committed to their customers’ sense of comfort will earn certifications to demonstrate their expertise. When you see a service company in Los Angeles 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 lower costs and speed up services: Technicians who spend the time and resources needed for these certifications often use 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.
