Condensation on windows — Alicante, Valencian Community
Persistent condensation, fog, or ice forming on the interior surfaces of windows during cold weather signals excessive indoor humidity. While occasional light condensation is normal, heavy or daily moisture on windows can cause wood frame rot, peeling paint, mold growth on sills and surrounding walls, and even damage to the wall cavity insulation. The root causes are usually inadequate ventilation, an oversized humidifier, bathroom or kitchen fans that aren't ducted outside, or a home that's been sealed too tightly without balanced air exchange. An HVAC technician can measure indoor humidity levels, inspect ventilation systems, and recommend solutions like balanced ventilation, dehumidifiers, or heat recovery ventilators.
Waarom dit veel voorkomt in Alicante
Alicante's extreme summer heat (regularly 38–42°C) makes air conditioning essential rather than optional, and HVAC systems work at maximum capacity for 3–4 months of the year. High UV exposure accelerates deterioration of outdoor condenser units and their mounts. Many older properties rely on individual split units rather than centralized systems, increasing maintenance complexity.
