I think it's more that air conditioning is (currently) prohibitively expensive. The few people I know that have it spent several thousands of euros on their installations. That's not something most people have lying around.
You'd think the government could subsidize aircon like they did solar for years, and both of those things combined would translate to very pleasant summers spent in energy neutral air conditioned homes.
