Hey droger!
This is'nt a job site but, I'll help steer you in the right direction...
Look @: http://www.hvacagent.com/
There are many more sites if you do a "Google" or other engines search like yahoo, msn, ask, etc. In other words, use your imagination!!!
BTW, if you know how to braze & solder really good, you'll do well finding work so, good luck and happy hunting!!!
Respectfully,
