They do indeed. For instance, Singapore uses the most energy per capita in the world (or top 3-4 depending on year)… and it’s mostly due to AC. Even with very high coefficients of performance (usually in the 2-4 range, meaning you can remove 2kWh-4kWh of thermal energy from a space with just a single kWh of electricity - remember ACs act as heat pumps essentially leveraging the refrigeration cycle), ACs are still total electricity hogs. Believe it or not, air conditioning systems sometimes even have to reheat the air! Sometimes you have to make the air much colder than desired just to dehumidify the air, and then you must reheat it to get it back to a reasonable temperature. There are some cool innovations in alternatives that don’t rely on all this psychrometric chart hacking, like using membranes and dissidents to perform the dehumidification, or using direct/indirect evaporative cooling etc etc. Edit: oh and of course space conditioning demands go up pretty linearly with total volume of air, which is in turn linear with total floor area. So could also just be a big home.
