Well, different from a central HVAC, where you set the thermostat and forget, with individual units I make a decision when to turn on and in which rooms. In the end, I only use cooling when temp gets higher than 26C (79F), and only on rooms being used, taking care to close doors. I calculate in a given week I have a total of about 20 hours of AC running, give it or take it.
And only during summer, winters are mild enough that no heating is needed (it would be electric if needed, not propane or oil)
