How to Become an HVAC Technician

HVAC technicians are typically required to take several steps to ensure they have the right skills and knowledge for the job. This is due to the increasing complexity of the equipment they work on, federal laws governing the refrigerants they often handle, and the importance of ensuring customer satisfaction year-round.

Formal HVAC training and Environmental Protection Agency (EPA) certification are the first two steps many people take to become an HVAC technician. Securing a license may be a third step, depending on location the HVAC tech works. On-the-job training is typically a fourth step, followed by specialized industry certifications that can lead to career advancement.[1][2]

Studying is a common step of any test-taking process. Many people also prepare by taking an HVAC training program. Some vocational schools require their HVAC program students to take and pass EPA Section 608 Core certification tests. This is the case at Midwest Technical Institute (MTI), which requires its students to pass the EPA Core Type I and Type II certification exams.

MTI offers a nine-month HVAC/R-MAR Technician Program at its campuses in Springfield, East Peoria, and Moline, Illinois, where students learn the HVAC/R and major appliance repair trade. An HVAC program is also available at the school’s campus in Springfield, Missouri.

Specialized Industry Certifications

As mentioned above, there are several industry organizations, such as NATE and HVAC Excellence, that offer specialized professional certifications. Their advanced certifications usually require formal training, a couple of years of relevant work experience, and taking and passing an exam.[11][12]

Becoming an HVAC Technician

It can take multiple steps to become an HVAC technician, but the effort could be well worth it. The Bureau of Labor Statistics (BLS) predicts much faster than average job growth for HVAC techs through 2026.[13] These professionals may also find satisfaction in providing comfortable, healthy indoor climates to their customers.
