HVAC Certification Online: Online Training Guide for HVAC Technicians

Working as an HVAC technician or working towards additional training in the field may be a serious and beneficial career move. Employment in heating, ventilation, air conditioning, and refrigeration mechanics has a projected growth of 15 percent over the next 10 years. This is higher than the average rate of all other occupations, including other trades. 

Needless to say, HVAC technicians and engineers are in growing demand. Moreover, in a world of ever-changing technology, HVAC systems are also changing and becoming more complex or powerful. That means, HVAC technicians can improve their employability and value with certifications and education. 

Finding time and means to go to classes at a school can be difficult. Not to mention, taking courses at a school or college can be expensive. Thanks to modern technology, many of these physical and financial barriers can be removed or reduced, allowing better access to certifications, diplomas, and licenses. 

Before making decision about your professional and educational career, it is a good idea to understand what online learning can do for you and what it cannot do. Luckily, this guide will help you in the journey of making a decision about HVAC certifications, education, and training online. 

What You Should Know First about HVAC Certifications and Online Learning

While federal law does not list any mandatory certifications for HVAC certifications, some states and local governances require technicians to hold certain certifications and licenses. While requirements may different between locations, the Environmental Protection Agency (EPA) has one mandated certification.

The Section 608 Refrigeration Recycling Rule directs that all HVAC technicians that can release CFCs into the air must be certified by the EPA and pass a test to so. All engineers and technicians must have their 608 cards.

NATE and the HVAC Excellence Certification are also nationally endorsed certifications that demonstrate training and knowledge in the profession. 

The required licenses vary between states, and these can be obtained by different regulatory or governmental bodies. You can research to find what certifications are needed where you live or work. 

It is always ideal to research the requirements within your state and research the programs, schools, and courses that you are interested in taking, whether that education is online or face-to-face. Some of the requirements may require training in-person, which will take you beyond the online classroom. 

At the most basic level, technicians need a GED, a HVAC certificate from an accredited program, an HVAC license from your state, and certificates depending on the kind of work you want to do.

Learning More About Online Certifications

Some online courses will lead to diplomas and degrees. Some schools and courses conclude with both a diploma and an examination that leads to necessary certifications. 

However, there are other online courses and state-endorsed HVAC certifications that can be obtained through experience and examinations. This combination is another potential path to certification. 

By receiving certifications in your state, you will be able to work within the field. This work includes installation, maintenance, and repairs. Other certifications may permit you to perform more advanced or complex work. 

Why You Should Study for HVAC Certifications Online

There are a number of benefits to pursuing HVAC certifications and learning online.

Other programs may offer you a degree without ending in a certification you may need. Assess what you need and what you hope to achieve and make sure the program fulfils your professional goals. 

Online Classes in HVAC Training Offer More Flexibility

Like any online course, studying online gives you a significant amount of freedom. Not only do you have a broader range of choices in both education and time. Brick and mortar schools have set semesters with mandated schedules, requiring you to be on campus or in the classroom established by the administration. 

Instead, you are offered more flexibility to work from home, which removes any commute time, and it also offers more flexibility to work online when you can. You can still hold a job and study in your free time, whether that is at night after work or during your lunch break. You can work at a pace that works for your learning needs and lifestyle.

Most online teacher have required, set office hours online. Many instructors offer virtual means of meeting, and some even can talk over the phone. 

Aside from your instructor, online resources, databases, and websites can help you answer questions you have. If you question is regarding the technology, nearly all school platforms have information technology personnel to help you through technical issues. 

Online classes can offer you more flexibility with the same amount of resources and access to information that other students may have. The online learning community is large, and you will not be alone.

HVAC Certifications and Courses Online Can Cost Less

It is common for online courses in any degree or field of study to cost less than courses taken at a brick and mortar school. This cost effectiveness extends to HVAC classes online. You can also apply for scholarships and financial aid. 

More importantly, you can continue to work, which means there is less likelihood you will need to talk out larger student loans. If time is also a concern, some courses offer a program where the courses can be completed within a matter of six to nine months.  

Therefore, taking courses online cannot only save you some time, but it can also save you money. 

The Downsides to Online Certifications & Learning

While there are great benefits to online learning and online HVAC programs, there are some downsides to digital and virtual learning. These benefits can be significant depending on your specific needs. 

Online HVAC Courses May Not Cover All Requirements

In many states and for some licenses or certifications, technicians are required to participate in an apprenticeship program. This is especially true for a master level license or certification, and it is also true for a journeyperson. Getting hands-on experience is crucial to having a well-rounded understanding of the profession. 

Additionally, most licensing demand and require resumes and apprenticeship hours that are notarized. Another in-person task is the actual examination. The examinations are proctored on established test sites and locations. The final examination for state licensing cannot be given or taken online. 

Regardless of whether you take a course online or in-person, you will still have to take the final examination at a designated location. 

If you are looking to have in-person workshops, some courses may or may not offer in-class HVAC workshops. If the program does offer in-class workshops, then you should take advantage of this. You can study the ideas and the concepts at home and then apply them in a practical sense in the workshops.

Short-Term Online HVAC Programs

Some schools offer significantly focused programs that seemed to move quickly. Speedy trade schools, programs, and community colleges offer a 9 to ten-month diploma-earning program in the HVAC field. While the theoretical and textbook information is done online, hands-on training and workshops will probably be part of your program. 

Some of the workshops may be able to count towards apprenticeship hours, but these programs are designed to give you the fundamental skills you need to pass your exam and become a technician. 

Two-Year HVAC Programs and the Online Associate Degree

Many two-year programs offer the same fundamental knowledge as the shorter programs, but these will expand that knowledge. Moreover, these programs with most likely end with an Associate Degree in hand. This will make you more valuable than entry-level technicians that only hold a GED.
