The Bureau of Labor Statistics (BLS 2023) reports that openings for heating, ventilation, air conditioning, and refrigeration (HVAC or HVACR) professionals will grow by 6 percent between 2022 and 2033, which is significantly faster than the average growth projected for all occupations during that time period (3 percent).

So what is the most convenient way for people to join this profession on the rise? One possibility is to enroll in an online HVAC training program.

With the widespread adoption of distance-based education through online certificates, degrees, and continuing education units (CEUs), aspiring HVAC professionals are now allowed to on-campus training programs. Online HVAC training options leverage streamed web lectures, digital simulation tools, and computer-based assignments. Through these innovative online HVAC programs, students can receive rigorous training in HVAC testing instruments and service equipment, residential and commercial HVAC set-ups, electrical and heat-pump systems, and more.

As coursework is done at a student’s own pace, online HVAC training is generally best suited to students who can self-motivate. For students who are currently working, cannot relocate or travel long distances for school, or for current professionals who wish to transition their careers, choosing to do one’s HVAC training online can be a way to gain career skills that don’t require the complete rearrangement of one’s life around school.

Please note that some online HVAC schools and colleges require an on-campus intensive or an externship component to ensure that HVAC candidates receive adequate hands-on training in the field. Although not in every case, the externships can be completed locally. Also, a majority of the HVAC certification boards (e.g., North American Technician Excellence [NATE], HVAC Excellence, Refrigeration Service Engineers Society [RSES]) require those seeking certification to come to an approved testing site to demonstrate their competencies.

Finally, the state licensing requirements for HVAC professionals vary, but generally require some formal training (e.g., diploma, certification, degree) and years of experience, in addition to continuing education units (CEUs) to maintain active licensure.

Read on to discover the variety of ways that one can receive online HVAC training, including certificates, degrees, and CEUs.

Who Should Enroll in an Online HVAC Training Program?

While many may excel in a traditional classroom environment, others may discover that they are best suited for online learning. In making this decision, prospective students should carefully consider several different factors.

Anyone considering enrolling in an online program must fully understand the program’s campus visitation requirements. Some schools require an on-campus orientation, others an on-campus intensive at a regular interval, like once per semester or once per year, and still others may ask that you present your capstone project on-campus.

Online programs can be a highly attractive option for those who do not have the time to attend lectures, or who need to live closer to the campus to make travel practical. Others, however, may find it difficult to excel in such a program, particularly students who do not perform well without support from professors or their peers inside or outside the classroom in group study sessions.
