LPT: Set your window fans from blow to suck.

This time of year, many of us take advantage of the cool evening weather to use a window fan to cool the house off without AC. If you use a window fan, have it blow air out of the home, and open a window across the house. You will have much better results at swapping out the air and create a cross draft.

This is how we ventilate tanks on oil tankers, suck the air out and it will be replaced, and it works so much better.
