It depends on your location since regulations vary from state to state. That said, if you really desire to take your HVAC expertise and credentials to the next level, it helps to receive the right education and training that will not only provide you with the skills and knowledge you need, but will also prepare you for the examinations, licensing measures, and other certification programs that you’ll have to undergo to become a licensed and certified HVAC technician.
There are many advantages that come with being a certified HVAC technician. One of them is that a license gives you that added advantage over other technicians who are also looking for employment opportunities. Getting a license or getting certified will also say a lot about your level of competence and desire to keep on harnessing your skill. This will be advantageous to you as you take on bigger projects and more demanding tasks.
