Cutting the number down

Each degree you raise the thermostat in summer trims roughly 3% off cooling energy. Two degrees is a rounding error in comfort and a visible line on the bill.
A clogged filter makes the blower work against restriction for an entire season. Replacing it is the cheapest maintenance in the house.
Cooling load tracks the indoor/outdoor gap, so the same thermostat setting costs far more in a 100 F week than an 85 F one.
