EPA Regulations

EPA regulations under Section 608 of the Clean Air Act require that technicians who maintain, service, repair, or dispose of equipment that could release refrigerants into the atmosphere must be certified.

Technicians are required to pass an EPA-approved test to earn Section 608 Technician Certification. The tests are specific to the type of equipment the technician seeks to work on and the test must be administered by an EPA-approved certifying organization. It’s good to know that Section 608 Technician Certification credentials do not expire. The core test must be taken as a proctored exam in order to attain Universal Certification in the USA. Read our article about preparing for the 608 Exam. There are also some HVAC certification requirements that vary from state to state.

State requirements

HVAC certification requirements vary from state to state. However, most employers prefer to hire an HVAC technician who has completed formal training, which may include an apprenticeship or classroom instruction. We will help you understand the HVAC certification and NATE (North American Technician Excellence) HVAC certification process.

HVAC certification can be obtained after an individual completes certain training requirements in an accredited program. HVAC stands for heating, ventilation, and air conditioning, and this industry offers a large variety of specialties that have different training and education requirements. The popular careers in the field of air conditioning, refrigeration, heating, and cooling, will involve the maintenance and installation of commercial cooling and heating systems, new product design, and system engineers.

There are a number of skills that are required for commercial and residential installation, repair, and maintenance of HVAC certification units. Some of these HVAC technicians also referred to as techs, will receive training through associate’s degree or certificate programs or a related field, such as electronics. A program for installation training can be completed in a little as six months, or as long as two years, while the system designer education can be completed in two to four years.

There are currently two certificate options available for online HVAC training. An individual can complete a certificate program to become an Installer and repair tech, or they can complete a certificate program that focuses on HVAC system design. Both of these online HVAC training programs are designed to provide flexibility in the student’s schedule.

Certificate Program for HVAC Installers

This HVAC certification program will require the completion of one to sixteen classes or three hundred credit hours. A student will learn about different types of heat transfer methods, system components, and safety considerations. Many of these programs will lead to licensing opportunities and will prepare a student for an entry-level position as an installer.

For the individual that’s seeking an entry-level position, continuing education credits or wants to strengthen their knowledge of this field, this type of program will offer training in troubleshooting and installations of HVAC systems. A student will be eligible to take the certification exam once this program has been completed.

Courses for these programs can be separated into sections, or there can be several different classes. These courses will instruct the student on everything from repair and troubleshooting techniques to basic system information.

The fundamentals of the HVAC class will introduce a student to the industry and discusses the measurements for gas and air works. The second half of this class will focus primarily on safety. A student will learn the correct way to use personal safety equipment and how to use compressed air and fire extinguishers.

The HVAC electrical course will teach students about the characteristics of AC and DC circuits. This class teaches students how to use and read schematic symbols for electrical circuits. The last half of the course will feature the discussion of the application of alternation currents for different types of systems.

The HVAC refrigerant class will cover the components of refrigeration systems, including condenser units and compressors.

HVAC System Design Certificate Program

These system design programs will include instruction on the comparison of systems, code requirements, and digital controls. Online programs can be found through a community college or trade school engineering department or their professional studies department. A student will learn about how to evaluate various systems for maintenance requirements, repair, and system retooling.

This certificate program will consist of five to six classes. The student will need to have a bachelor’s degree and engineering experience in order to be eligible for enrollment.  A student will learn about the laws regarding the installation and design of HVAC systems, the controls used in these systems, and system calculations.

The design class consists of four different classes. The beginning class will introduce students to the components of HVAC systems and system classifications. The advanced classes will cover system comparisons, system costs, and HVAC equipment repair and maintenance.
