Hey guys, need some advice here. I've been in light comm AC/refrigeration, occasionally residential for couple of years, the company I work for has couple dozens of locations, so I'm sorta know all equipment we have, for the time I've worked on our units I did pretty thorough maintenance so service calls went down quite a bit, so I start to feel bored a bit and looking to jump in commercial/industrial/controls. But I have 0 knowledge about big machines and 0 experience in controls, so need your advice on how to get good training in these fields, maybe some classes, manufacturers training. Any links to websites of training programs(in PM please) would be appreciated.
Wonder how people get into commercial/controls?
