Average price of AC instalation in Spain goes from 550€ to 5000€ depending on what kind of instalation, equipment and units. Average wage is between around 1300€ net per month.
In Spain it's not cheap.
Edit. And also local towns have rules, I can't just install one that have a device on the outer wall/window and I own the whole house, in the flats you depende on the community to decide.
