econy is more important to people and more incentivised by society than following one's heart and feelings

Uh yeah, because if you don't fit into the "econy" then you get treated like shit and die prematurely. People are more concerned about survival than being nice? SHOCK AMAZEMENT.

Even if the AC would have infinite efficiency (instead of typical values of 2-3), you are increasing temperature out-of-the-house by reducing temperature in-house

So then, you can just shut off your AC and just have it permanently cooler inside, right?

Wait, no you can't?

That's right, because heat leaks back into the house from the outside - warming your house, and cooling the exterior. And the amount it cools the exterior is approximately equal to the amount you're pumping out. Only the energy used by the AC is actually changing the outdoor temperature. But it's utterly dwarfed by the impact of the sun.

(I stress "approximately because there's some slight radiative balance changes - the heat outflow is a point source while the inflows are diffuse, and thermal radiation is proportional to the temperature to the fourth power - but it remains a trivial factor in practice)
