Setting the AC to 20° doesn’t cool faster: how to use air conditioning right (and pay less)

When the heat arrives and the house feels like an oven, many people do the same thing: switch on the air conditioning and turn the thermostat down to 20°, thinking it will cool down much sooner. It seems logical… but that’s not how it works. The unit doesn’t blow colder air just because you set a lower temperature: the only thing that changes is how long it runs and how much it consumes while trying to reach that target.
