Single-stage furnaces waste energy when they run at full capacity, stop, run at full capacity and so on. They heat past the thermostat set point, and that hurts both indoor comfort and efficiency. A two-stage furnace runs at 70% capacity most of the time it is heating. This gives you better efficiency.
