Blackout shades for one. Second, I close all the vents in the basement and first floor. This makes all the cold air release on the second floor and keeps the thermostat from recognizing the colder temp of the first floor without cooling the second floor.
Some would recommend against closing all but the second floor vents because the air conditioner might freeze the cooler fins. Thinking there might not be enough airflow through system because of the restriction. We have never had a problem however.
Yeah, I did something like that too (closed about half the vents). We live in a 4 level split, and the top floor is always too warm or too cold.
