Ductwork condensation and sweating — Valencia, Valencian Community
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.
Waarom dit veel voorkomt in Valencia
Valencia averages 300+ sunny days per year and summer temperatures regularly exceed 35 °C, making air conditioning near-essential rather than optional — AC failures in July–August are true emergencies. The city's proximity to the sea creates a corrosive saline air environment that degrades outdoor condenser units faster than inland locations. F-Gas certified technicians are required by law for refrigerant handling (RD 115/2017), and demand for certified installers spikes sharply in spring, creating booking waits of 2–4 weeks.
