Why Barcelona homes get this: 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.

That is several times the size of a typical Spain city we cover. Ownership is split — 60 % owner-occupied — so a typical week mixes homeowners with landlords and property managers who buy in volume. The housing stock is old for the country, which pushes repair and replacement demand above the national average.
