The requirements surrounding HVAC licenses are mostly set at the state level. This means that two neighboring states may have wildly different requirements when it comes to who can and can’t become an HVAC technician. Relocating will allow you to deal with less harsh licensing requirements.
It’s hard to gauge how good the job market is when you aren’t an active member of your profession. But if you learn that the job prospects for HVAC technicians in your state aren’t very good, you may be better off relocating before you start your training, as that will improve your odds of future success.
Make sure you do your due research before you make any drastic decisions. Sites like https://www.hvacschools411.com/ can help you get informed about the HVAC profession.
