How's it going everybody, I stumbled across this site while looking for info on EPA certification and seeing that I am just getting started to becoming a HVAC tech ( I just started school) I thought I would join the forum. Looks like a great site with a lot of knowledgeable people here. I look forward to being able to join in on some discussions as soon as I learn more. I am just now getting into the Nature of Electricity. So I hope you don't mind if I lurk around a bit. Justin
