Hello to all. I've visited this site several times in the past and decided recently to join. Been in the Industry for approx. 28 yaers. Earlier years in the residential and light commercial sector. Service / Installation Mgr. from 1989 - 2001. Technical Instructor for 2 1/2 years. Before becoming an Instructor I did obtain several Nate Certifications. Love this Industry. I did obtain my type A HVAC contractors liscense a couple of years ago.I can still remember where I came from, why some things are hard to grasp and understand. I feel at times we tend to run off good future prospects (future technicians) by not remembering when we ourselves first got started in this Industry and at times being somewhat harsh or arrogant in our responses to them. Anyway enough of that, nice to meet everyone.
