If I come out, will it be hard to actually find a job like some tell me? Is it a good idea? I talked to a recruiter and I am not sure if it will benefit me and my HVAC career in any way.

To tell you the truth I really do not see sight glasses in the field that much. Like someone else here said they are more better for new techs to see how much liquid refrigerant is going through your...

Me and my brother were talking about college lately, and how its a waste of time and money. I myself think its a total waste of time and money. Why spend 30-50k a year for 4 years going to college...

I don't know anyone who carries around a 20k ohm resistor either. Definitely use a screwdriver. Your teachers just tell you that because they have to give you the most professional methods available.
