What Do You Need to Become HVAC Tech?

Educational paths for HVAC technicians can vary. However, HVAC technology has become increasingly complex, so employers nowadays often prefer to hire candidates that have completed postsecondary education. Some states or localities may require HVAC technicians to be licensed.


High school students who wish to work in HVAC might want to consider taking classes in math and physics. Having a basic understanding of electronics is also useful. The three most common educational routes towards becoming an HVAC technician are on-the-job training, HVAC training from a vocational school, and apprenticeships.

On-the-Job Training

Some aspiring HVAC technicians may learn the trade on the job. They work under experienced technicians and first perform essential tasks, like insulating refrigerant lines or cleaning furnaces. Once they have gained more experience, they advance to more sophisticated job duties, such as soldering pipes or checking electrical circuits.

Vocational School

Vocational training programs prepare students to become an HVAC technician by providing a combination of hands-on practice and classroom lectures. Students of the Delta Technical College HVAC training program learn about basic electricity, air conditioning, heat pumps and electric heat, major appliance repair, gas heat, and indoor air quality. The HVAC technician program is nine months, and students receive a diploma upon completion.

HVAC Technician Certifications & Licenses

While all HVAC technicians handling refrigerants must obtain Environmental Protection Agency’s (EPA) Section 608 certification, some may also need additional licensing depending on which state or locality they work in.

EPA Section 608 Certification

The federal government mandates that all HVAC technicians who maintain, service, repair, or dispose of equipment that could release ozone-depleting refrigerants must pass the EPA’s Section 608 certification exam. There are in fact four types of certification tests:

  • Type I (servicing small appliances)
  • Type II (servicing or disposing of high- or very high-pressure appliances)
  • Type III (servicing or disposing of low-pressure appliances
  • Universal (servicing all types of equipment)

Each test also has a Core portion testing HVAC technicians on general HVAC-related subjects, including refrigeration, ozone depletion, safety, recovery techniques, and Section 608 regulations. At Delta Tech, students must take and pass the Core Type I and Type II certification exams.
