Cutting the cost

Zone it. Only condition the rooms you're actually using, close the vents and doors elsewhere, and hold a moderate thermostat setting rather than blasting cold air. A gentle set-point costs far less to maintain than a chilly one, and running the fan on "auto" stops it circulating once the room is comfortable. Service the filters before summer so the system isn't fighting a clogged return.
