Congratulations on buying in Spain,

Air Con ducted systems are fine and the heat they produce usually surprises new users. I'm based near Alicante in Spain and normally the builders include an internal ducted pre-installation on each floor, usually the indoor units are situated within the false ceilings of the kitchen or bathrooms. Builders usually charge an arm & leg for this simple service but there's not a lot you can do. They should also provide the power supply to the unit as it needs a seperate circuit so the tariff should be sorted. 

Basically, in Spain,  the Summer heat is unbearable in July & August and so you most certainly need a/c fitted, therefore you might as well take advantage of its heating in winter.

If you treat it like central heating you won't go far wrong.

The main disadvantage to ducted systems is the lack of individual control to each room ie. to cool a downstairs bedroom overnight you will end up cooling the lounge as well, or cooling a main upstairs bedroom, you may have two other bedrooms that you dont need but are also cooled.  You can fit seperate dampers which close off the individual vents to the rooms but they add to the initial installation cost.

For  a very approximate price for a lounge and one bedroom or three average bedrooms, your looking at something from around €1120 per unit, €2240 per dwelling.
