Ductwork condensation and sweating

Answer: call a hvac technician.

Sweating ductwork occurs when warm, humid air contacts cold duct surfaces, creating moisture that can drip onto ceilings, insulation, and framing. Left unchecked, duct condensation leads to water stains, mold growth, and damaged insulation. An HVAC technician can insulate ducts, seal leaks, and adjust humidity levels to eliminate the problem.
