Ductwork rattling or popping — Alicante, Valencian Community
Rattling, popping, or booming sounds from HVAC ductwork are usually caused by thin sheet metal expanding and contracting as heated or cooled air passes through. While not always dangerous, the noise can indicate undersized ducts, loose connections, a clogged filter creating excessive pressure, or poor duct support. An HVAC technician can identify the cause, reinforce or resize problem sections, and seal joints to eliminate noise and improve efficiency.
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.
