Cutting the cost

Pick a moderate temperature and leave it there; chasing a colder room just runs the compressor harder for longer. Clean the filters often, and keep the outdoor unit clear of leaves and harsh afternoon sun so it can shed heat. In milder weather, try the "dry" or fan mode instead of full cooling, and close the curtains before the room has a chance to heat up.
