Union or open shop?
Union
Run by a joint committee of the SMART sheet metal local or the UA pipefitters local and union contractors. You apply to the committee, take an aptitude test and an interview, and wait on a ranked list. The committee sends you to its contractors.
Pay is a set share of the union journey-level rate and steps up on a schedule. Classes are nights or week-long blocks, usually paid for by the program.
Open shop
Run by ACCA or PHCC chapters, ABC or a single HVAC contractor. You usually get hired by a member contractor first, and the contractor enrolls you.
Your employer sets the pay and the raises. Classes are nights or weekends, and some programs charge tuition.
