re: Ways to keep house cool while waiting to repair AC situation.

Just to follow up with what the problem was. Faulty capacitor in the AC unit. Was going in and out. Must have been something that got worse and worse over time. When they came the first times, I guess they took their measurements when it was on. This time, the guy could see it kicking on and off. Was providing enough compressor "on time" to cool off in evenings, but not in the heat of the day.

Still getting insulation quote today though in case and they are addressing the attic ventilation.
