Sweating presents itself in an air distribution system as moisture that forms on the faces of lay-in diffusers and T-bar grids adjacent to those diffusers, where this moisture collects and drips into the areas below. While sweating may be a simple annoyance, it may also be potentially dangerous. Either way, it is a symptom of a larger problem.
“An epidemic of moisture-related problems are causing more system failures today than ever before in the history of air conditioning and refrigeration,” said Paul Appler, a technical speaker at the state of Alabama’s mandated Continuing Education Program for HVACR Contractors.
