HVAC & Pipefitter Salary in St. Louis
Metro area wage data from the BLS OEWS program (May 2025), with Davis-Bacon journey-level scale from UA Local 562, effective July 2026.
The federal wage data on this page covers heating, air conditioning, and refrigeration mechanics and installers, work that is largely service, maintenance, and residential installation. The union scale shown is journeyman pipefitter, which covers refrigerant, chilled water, and hydronic piping on commercial construction and falls under a different federal occupation code than the wage data above. Duct fabrication and installation is sheet metal work, represented by a separate union called SMART (the International Association of Sheet Metal, Air, Rail and Transportation Workers), and is not reflected in either figure.
