I think the bumping the AC up to save money is a myth. Something about cooling down thermal mass.

It's not a myth, it's just that there are a lot of factors that determine how much it will save, if any at all.

Obviously if OP went out of town for a week and had it on 80 the whole time, he would save some money. Is he saving anything doing that daily? I don't know, doesn't sound like it if it takes over 2 hours to get down to 70. Maybe his house is poorly insulated, or maybe his unit is undersized (TWSS), or both.

It has saved us money, but we also run ceiling fans on high all day and bought better curtains and blinds for the windows that get a lot of sunlight. The monthly savings is only about $5-$10 though.

Thermostat is set at 71 from 3PM to 7AM, and 78 from 7AM to 3PM during the week. We keep it on 72 on the weekends when we are home.
