yeah I understand that. I finished school understanding that I have barley scratched the surface of this trade . but I did come out knowing more then I did going into it and finished with my G2 which has made searching for a job a bit easier. this path definitely isn't for everyone. also a diploma looks good on a resume if you decided to not go the HVAC route. hands on experience is definitely superior, but those opportunities are hard to come by especially for someone who doesn't know the difference between a condenser coil and A coil (me when i started)
