Doctors, lawyers, scientists, engineers, financiers, and dozens of their assistants such as RN’s, biomedical techs, nuclear imaging techs, dental hygienists, paralegals, and accountants must have a college degree plus state certifications.
Many certifications are recognized across the nation and occasionally in other countries.
The HVAC industry can be much more complicated that other card holding careers. Very few trades require more than one certification or license. In the HVAC world, most people have to have the EPA section 608 card. Union members may have to possess a journeyman’s card, but it can be even more difficult for an HVAC engineer to just bounce around every few years. During my research into HVAC employment demand I found out some cities require municipal licensing. You could possibly be required to hold a propane license, steam license, boiler license, oil boiler license, and/or refrigeration license. Environmental laws can vary state to state and a newly elected politician can literally clean the clocks of an entire sector if he/she chooses to do so. Depending on their sense of urgency regarding climate change, standard requirements can double. A few states require electrical and plumbing licensing to work in HVAC. Contractors have just as much chaos to go through before they can start bidding, especially in big solar states. The list of state contractor licenses across the United States is astounding, with the list of requirements being almost the same length. When an individual wants to work on furnaces, cooling coils, and water heaters, he or she may want to look into local requirements as well as the price of obtaining those prerequisites. Comparing the cost of licensing, cost of living, and salary opportunities to other cities and states would be the smart thing to do before nose diving into local HVAC.
