Demand for heating, ventilation, and air conditioning (HVAC) technicians is expected to rise much faster than average, at a rate of 9% between 2023 and 2033, according to the U.S. Bureau of Labor Statistics. With demand on the rise, now is the ideal time to pursue a career in the HVAC trade.

HVAC technicians start their careers with an apprenticeship, trade school, or vocational college. Aspiring technicians can then pursue certifications, such as an HVAC EPA, NATE, RSES, RETA or other certifications, to specialize in certain areas of the trade. Apprenticeships and certifications offer two paths to gaining employment in this field.

Which path is the right choice for you? It’s important to understand what each option entails and weigh the pros and cons before making a decision.

How Can Emerging Technologies Enhance HVAC Careers?

Integrating advanced digital tools with traditional HVAC training equips professionals to tackle modern challenges in system automation and energy management. Embracing emerging technologies—such as predictive maintenance software, smart system controls, and automation analytics—can optimize operations and offer strategic advantages in competitive markets. Supplementing technical education with courses in affordable online artificial intelligence degrees provides practitioners with innovative methodologies to enhance efficiency and drive career growth.

What is an HVAC Apprenticeship?

Apprenticeships last three to five years, depending on the state, and offer a path to acquiring a state license. As an apprentice, you’ll work under a mentor who shows you how to work on HVAC systems, including installation, maintenance and repairs.

Apprentices require a GED or high school diploma, must be 18 years or older and meet other requirements that vary from state to state and company to company. Although having a college degree can positively impact future salary and job security, it’s not always necessary.

During an apprenticeship, practical experience under the tutelage of a mentor is the main goal. Training in a classroom setting will take place a few times a week to learn local codes, laws and regulations.

An apprenticeship license is the first form of licensing offered by most states. After an apprenticeship, technicians can pursue:

• Journeyman license: A journeyman will work under a contractor or master technician to gain experience working on critical HVAC systems. Once the license is obtained, the professional can conduct work independently without supervision.
• Master license: A master license offers the most experienced HVAC techs the ability to work without limitations or restrictions.

Licensing requirements vary from state to state, and contractors must check with the state’s licensing board to determine current requirements. 

Can Supplementary Online Learning Broaden HVAC Competence?

In a rapidly digitalizing industry, integrating online education complements traditional HVAC training by enhancing technical and digital proficiencies. Supplementary courses in data analytics, process optimization, and smart system controls offer HVAC professionals additional tools to address modern technological challenges and optimize system performance. Exploring diverse educational options, such as the most affordable nursing informatics programs online, can introduce innovative methods for data integration and system diagnostics without overlapping core HVAC expertise.

What are HVAC Certifications?

Certifications help HVAC specialists acquire specialized knowledge and mastery from specific organizations. While a license is required to work as an HVAC tech, certifications are optional and often sought for career advancement.

Technicians can seek:

• EPA Certification: One of the most common certifications for HVAC techs is the EPA certification, which allows you to work with refrigerants. Four certification levels exist and offer specialization in small, low- and high-pressure appliances.
• HVAC Excellence Certification: An employment-ready certification that over
• NATE Certification: A certification that shows working knowledge in HVACR systems and is similar to the HVAC excellence certification. NATE offers entry-level and professional certifications with options for low GWP refrigerants, ground source heat pumps and more.

RSES and RETA certification are two additional popular options that offer career advancement. Employers may require certifications or offer to pay for any costs related to obtaining certifications.

Key Differences Between Apprenticeships and Certifications

HVAC licensing and certifications are intrinsically different. Apprenticeships are, in some states, a requirement and train the HVAC professional under the guidance of a master technician. Practical, hands-on skills are learned on the job, and the mentor examines the work, makes recommendations, and shows you how to perform certain tasks.

Apprentices work toward licensure, while certifications show proficiency in specialized areas.

Technicians seek certifications to boost their resumes and increase wages, but licensing allows the professional to work in the field.

Pros and Cons of Apprenticeships and Certifications in HVAC

Apprenticeships and certifications both have advantages and disadvantages that should be considered when choosing your path.
