I am a very green tech, and I am looking for help. After graduation there is a great deal of knowledge that I am lacking. We learned next to nothing on boilers. No hands on with oil, and very little with heat pump troubleshooting. Does anybody know where I can find video instruction to help me in these areas? I know of Mynoravideo. The videos can be online, dvd, free, or pay. I just want to hone my skills with as much info as I can get, but I learn better by seeing than reading. Thank you.
