Why attics make it worse here
A Nashville attic can run far hotter than the outdoor temperature on a July afternoon. Every leak in that space is losing conditioned air into the worst possible place.
Sealing usually shows up as a system that reaches setpoint sooner and runs less, which is the same thing as a smaller power bill.
