Depending on the house that might be a problem or it might be extremely expensive. In that case ask your expert if it might be as effective to cool each room individually, and only when someone of your family needs AC at that moment.
Also make sure that if you buy a small room air conditioning system you get the right size. If you buy a model which is “too strong”, you will get a cool room quickly, but a very damp one.

And one last tip: No matter if you have central AC or small room air conditioners for cooling: If you close the room doors behind you all the time, you prevent too much circulation of air in your house. By that you save a lot of cooling energy.
