Ductwork rattling or popping — Valencia, 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 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.
