I work for a comercial HVAC company. I had about 1 years experience with a residential company then worked in manufacturing for about 4 years and have been with this company for about a year. Before I started with the comercial company I took an HVAC course through Penn Foster just to get the very basic knowledge(I know thats not the best type of training). Right now im an assistant technician(mostly help on jobs where another set of hands are needed). I thought training and experiance I got in the field would be enough coupled with the course I took to become a good technician. Now my employer wants me to go to the local community college and take HVAC courses. I dont have a problem with that but I was wondering is it really going to help me? Most people I talk to say they didnt come out of school knowing how to do anything, but learned most eveything in the field. Like I said I dont have a problem going to school or doing anything else that will help me get better but im just wondering what to expect. I thought I would be further along after doing it full time for a year, but I have been doing a little bit of everything not just helping on service calls. I just want to hear others experience. How much did you come out of school knowing? Do you think the school is important or is time in the field a good equivilant? How much can I expect to learn in school? What should I be able to do in the field when I finish school? Also I know I have a long way to go but I think I can do a little more than they are letting me do right now(about the only thing I work on myself are exhaust fans and clogged drain lines). How can I get them to let off on the leash a little bit? Prove to them I know more?
