Pardon me if this isn't the right forum--I'm a newbie and admit it. Please redirect me if needed...

I'm taking my HVAC class that leads to the EPA test, so I'm new at all this stuff--even though I do have general light construction experience in plumbing and electrical. I just finished the sections on brazing and soldering, and I'm a little confused. I went into HVAC under the impression that soldering was pretty much all that was need. I didn't know that--according to the books--brazing is really the skill most used.

I just wanted to find out from some of the pro's what the real story is. (I'm new to HVAC, but not to schooling and life. That means I know the books don't always teach what is right, or what is common practice). Thanks in advance for any input.
