Actually, Brother, just as a Plumber isn't a Pipefitter - we aren't Pipefitters. Right now the U.A. is looking to reclassify us as "HVACR Techs", in either Construction or Service. It sound good to me, but will it work? As maxster said, in NYC, Steam/Pipefitters do the line sets. Usually in most smaller jobs, Service does the line sets.
If Source ever joined the U.A. for example, has 35% of their business as Construction. So would they have over 350 "Construction - HVACR Techs" and over 700 "Service -HVACR Techs" or simply classify everybody as "Service"?
