Hey I'm considering entering into the HVACR industry as a career. Although I'm a little confused on what a Refrigeration mechanic actually does and what he doesn't do...
Do refrigeration mechanics only work on the "refrigeration" side of it or are they licensed to do any electrical/plumbing/gas parts of it too, or would a electrician do electrical, plumber do plumbing, gasfitter do gas? Do refrigeration mechanics do their own electrical and plumbing? Or would I have to get extra trade tickets to be certified to work on electrical?
Also when ductwork needs to be run say in residential or commercial settings, who actually installs the duct work? Is it sheet metal workers, or the HVAC guys? Do you have to be liscensed to do ductwork and sheet metal work?
