Air conditioning
Air conditioning is the century's appliance in Barcelona: the wall split with heat pump — which heats in winter — is the city standard.
The heat-pump split
One outdoor and one indoor unit per room, with a reversible heat pump: it cools August and heats January with contained consumption. The serious technician sizes by square meters and orientation, not the month's offer.
Installation and permits
Facade installation may need community and city consent in protected buildings: the good installer resolves it before drilling. Ask for a quote with material and paperwork itemized.
Maintenance
Filter cleaning every season — yourself — and a full check every couple of years: performance drops with dirty filters before it does with old age. The maintenance contract cheapens August's breakdown.
