Please don't make assumptions on something you don't know anything about.

Even many northern US states (around the same Latitude as Madrid, north), on average, are 30-35+ every day during the summer and 0C to -10C in the winter. Many Canadians have air con.

So yes, heating and air con is a requirement in many areas. I live in a northern state, and we regularly have full weeks that are 38-40C.
