Ductwork condensation and sweating — San Francisco, California
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.

The cool, foggy maritime climate means central AC is rare and rarely needed, so HVAC work centers on heating efficiency, ventilation, and increasingly heat-pump retrofits driven by Title 24 energy rules. Older homes often have undersized or outdated heating systems requiring careful upgrades.
