Ductwork condensation and sweating — Madrid, Madrid
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.

Madrid's continental climate demands both: substantial winter heating for sub-zero nights and increasingly powerful summer AC for 40 °C+ heat, so many homes run dual systems that double the maintenance burden. F-Gas certified technicians are required for refrigerant work, and demand splits into an autumn heating-prep peak and a late-spring cooling-install rush, with installer waits at both.
