This effect is temporary. Otherwise one could run their AC once for a few minutes and then it'd be cold inside your home for the rest of the year until you turn up heating.

In reality equilibrium is restored quickly (and the thermal mass we're cooling/heating here is insignificant anyhow).

The process of moving heat from your house outside also creates excess heat, because no AC system is completely efficient (and it can't be because of the second law of thermodynamics).
