I start my apprenticeship in June with a great company. I didn’t know a lick about HVAC when I signed up. I’ve since gotten familiar with the refrigeration cycle,other basic hvac related things like what a split system is,window units,package units.Typically just the basics.However, WHERE do I go from here,like tips that will actually help me be ahead on day 1.
