I don't think anybody was trying to put him down, but was rather offering a 100% true opinion.Dont listen to the ones who have to put people down on the internet to feel good about themselves.
A 2 year course in electrical alone is fast paced and truncated for brevity, trying to squeeze HVAC in the same time period means course material is only touched upon and then quickly moved on.
I could not find an electrical and HVAC program in Virginia, they were either electrical-mechanical or HVAC. Though some of the 2 year HVAC certificates did include NEC and electrical theory as part of its course study.
Either way there is nothing wrong with education as it can only help get your foot in the door. Now you need an apprenticeship to show you that everything you learned in the last 2 years will never be seen in real life.
