Maintenance Technician Hvac

I have work for my current employer since March * of 2007. The company is Case associates I’ve been a lead maintenance technician for 13 years out of my almost 15 year career. I do already have my EPA universal and our 410 a certificate. I have about 14 years of experience working with Residential heating and air and appliance repair. But would love to further my career and HVAC and get a Journeymans license go from there.
