Uneven heating or cooling between rooms — Barcelona, Catalonia
When some rooms are too hot while others are freezing, the problem usually lies in your HVAC ductwork, insulation, or system sizing. Common causes include blocked or leaking ducts, closed or misadjusted dampers, insufficient insulation in certain walls or attic areas, or an HVAC system that's too small for the space. An HVAC technician can perform a duct inspection, check airflow at each register, and recommend solutions like duct sealing, damper adjustment, or adding a zoning system.
Why this is common in Barcelona
Barcelona's humid Mediterranean summers make AC near-essential, but Modernista heritage protection across the Eixample restricts where outdoor condensers may be mounted on catalogued façades, often forcing roof or light-well installations. F-Gas certified technicians are required for refrigerant work, and salt-laden coastal air corrodes outdoor units faster than inland Catalonia.
