Air Handling Water Treatment and Plumbing Systems (SYS-4103.05) HVAC technicians installing commercial systems must size water-treatment loops correctly or risk corrosion failures costing thousands. SYS-4103.05 covers the practical intersection of air handling, water chemistry, and plumbing code compliance that determines whether a building’s mechanical systems run silently or create liability. Field experience shows most failures stem from overlooked condensate line routing or incompatible treatment protocols—exactly what this credential addresses.
