I own a 2100 sf house in Florida that I am desperately trying to cool off. In the middle of summer it is not uncommon for my house to be 80 degrees inside. The house and AC are only 5 years old. The AC installers have said the AC is of the correct size and working fine. THe only venting I have in the attic is the static gable vents. What would be better given the situation, motorized gable end vents, one on each end of the house, or ridge vent running the length of the house? My soffits are perforated vinyl and are 360 degrees around the house. Any info would be greatly appreciated.
