I've been in the HVAC field for 7 years now. I received a scholarship out of high school from auto mechanical and used it on a HVAC trade school. I started in installation for 3 years and the last 4 have done routine maintenance and some service repair. I have my EPA but I want to get more qualified. I know there is NATA and I would like to get my license sometime. I was looking up NC HVAC licensing I saw a Contractors License and Technician License. Is this journeymen and masters?
My main thought is I want to gain more licensing for better pay and I always strive to do the best I can.
What should I do? NATA, NC License or something else?
