In my cold(er) part of the world no one has a dedicated AC but lots of people have heat pumps for heating, which can be used as an AC during the (annoyingly few) hot days. But while their efficiency is great (3+ kW heat for 1kW electricity) I think most units are less efficient when used for cooling? Might be wrong though.
My electricity bill with heat pump heating (one exhaust heat pump and one split) and relatively cheap electricity is still pretty substantial. 25000 kWh per year for 150sqm/1600sq ft. Usually pay $0.30/kWh for power.
