If you change your capacitor value check before and after motor amps to make sure you're not increasing your power usage.

So if longer furnace run times are more efficient then one easy improvement would be to set your thermostat program settings with more differential. This makes sense if you leave for work or if you have 2 hvac. We sleep upstairs so downstairs can be shutdown all night. After everyone leaves both units can set back 10 degrees.
I also stagger my schedules so downstairs runs before upstairs to anticipate the heat rise and prevent overshooting the upstairs set point. "Losing" the heat to the upstairs also increases my run times.
If your house is already tight and insulated there might not be much of a temperature drop before you return but you should get the extra temperature swing to take advantage of optimized heating temperature.
