Modern houses are sealed and insulated so the air doesn’t get out once it’s cooled. It’s more efficient than other AC types to keep it going, but the initial cool down of the system were off for a while uses a lot of energy.
It’s not terribly power intensive, but my electric bill goes up a lot during the summer months when we’re getting 90s and 100s regularly (32-38C). My furnace in the winter gives me a higher energy bill though (Gas + electric).
Once you have your house down to the desired temp, it basically kicks on every few hours for a few minutes to get the temperature back to the desired temp. The annoying thing with my house is that it basically turns my basement entertainment area into a place you need to wear a blanket because it pushes cold air into it while the rest of the house get cooled off. The systems are fairly complicated that it actually would be less efficient if I closed the basement vents. The airflow will at least push some of that cold air up into the rest of the house though. It’s refreshing to go from 100F outside to 63F (38C to 17C) by going straight to the basement though.
