Lloyd Meissner, P.E. describes a project he worked on involving residential HVAC systems that were the subject of a class-action lawsuit. The manufacturer asked ESi to investigate the plaintiff’s allegations that poor design and manufacturing practices were responsible for the corrosion that made its way into the condensate from the cooling coils, and left rusty streaks on the buildings. Specifically, the plaintiff asserted that:
Residual oils left behind during manufacturing caused corrosion in the system. Failure to re-coat areas of the zinc-plated sheet metal after it was punched and trimmed caused additional corrosion.
