Thanks for adding me to this site. I joined the HVAC field in August of 2005 and was a lineman previous to that. I went to Community College and received my associates in Stationary Engineering. I have also been licensed through the City of Chicago as a boiler operator. Sadly though the building I work for, the closest thing to a boiler are 200 gallon hot water heaters. LOL! As for the electrical side of things ie: trouble shooting, wiring and install is my strongest field at this time. But hopefully I will continue to gain knowledge as I follow this site.
