How to Become an HVAC Technician in New Jersey – HVAC Contractor License

Those born and raised in New Jersey hold a unique pride in their state. If you’re thinking of joining them or are already in NJ, you might be considering a creditable career in heating, ventilation, and air conditioning (HVAC). 

HVAC techs in New Jersey make about 10% more than the average tech in the U.S. One of the highlights of the HVAC industry is that you can begin working straight out of high school by attending a trade school or an apprenticeship program. You can then further your career through optional certifications or aim for your HVAC Contractor License from the state itself.

The State Board of Examiners of Heating, Ventilating, Air Conditioning, and Refrigeration Contractors only offers HVAC Licenses to HVAC contractors. These individuals work for themselves and may employ other HVAC techs. 

HVAC techs do not have state requirements or licensure procedures; however, some jobs may require HVAC techs to hold certain certifications to legally work with refrigerants or high-pressure and low-pressure boiler systems.

Types of HVAC Licenses in New Jersey

This article will discuss the following licenses and certifications for HVAC techs in NJ:

Becoming an HVAC Tech in NJ

Before applying for a license or certification, you will need to have sufficient knowledge and experience in the HVAC field. Most HVAC techs begin their careers after finishing high school, through either a trade school program, associate’s or bachelor’s program, or an apprenticeship.

Trade schools focus on teaching you a specific skill set related to HVAC work. These programs can last anywhere from 6 months to 2 years. Sometimes trade school credits can count towards an associate’s degree.

Associate’s or bachelor’s degrees in an HVAC-related field serve as a great knowledge base for work and licensure. 

Apprenticeships incorporate classroom learning with paid, hands-on experience. These generally last at least 4 years and have you working under a licensed and/or experienced HVAC-R (refrigeration) tech to learn the ropes.

EPA Technician Certification for HVAC Techs

Many HVAC techs work as HVAC-R techs, handling refrigerants and working with different refrigeration systems. Since the Clean Air Act was passed over 20 years ago, HVAC techs working with refrigerants have been required to hold the Section 608 Technician Certification. 

There are four specifications for this certificate, and each is earned after you pass the correlated EPA exam. 

  • Technicians working with small appliances should receive their Type I Certification. 
  • Technicians servicing or disposing of high- or very high-pressure appliances need the Type II Certification. 
  • Technicians servicing or disposing of low-pressure appliances require a Type III Certification. 
  • Technicians who want to work with all types of equipment need the Universal Certification. This certification is given through a proctored exam and cannot be open-book.
