2. In-Depth Course or Topic Breakdown

💧 What Is Water Treatment in HVAC Systems?

Water treatment in HVAC systems refers to the process of managing water quality to prevent scale, corrosion, and biological growth in systems that rely on water for heat exchange—like boilers, cooling towers, hydronic systems, and chilled water loops. Untreated or poorly treated water can lead to:

  • Reduced system efficiency

  • Expensive repairs

  • Equipment breakdowns

  • Shortened system lifespan

  • Unsafe indoor environments

Proper water treatment protects the system’s integrity, ensures clean indoor air, and helps reduce operational costs.

  • The causes and effects of scale, corrosion, and fouling

  • Water treatment techniques (chemical dosing, filtration, softening)

  • How to maintain cooling towers, boilers, and closed-loop systems

  • Best practices for monitoring and testing water quality

  • Compliance with ASHRAE standards and EPA regulations

Whether you’re working in residential boiler systems or large commercial chillers, these lessons are essential.
