1. Use Air conditioner for home at night:
Temperature outside = 69F, Temp in home = 81F,
Air conditioner trigger set to 75F

method A. With windows being open - My way
method B. With windows being closed - Wife's way

Question: which one make house temp drop faster and which one costs
less electricity?

PROBABLY B.

What you say? Simple..opening the windows will remove some of the warm air,
but unless you have a whole house fan pulling like hell, you wont be able to
use all that cool air out, and you still have latent heat in the walls,
floors, ceiling...furniture...etc..

Why latent heat, ie condensation?

But my queston is....why are you allowing your air in the home to reach 81F?
Set your thermostat and forget it...its cheaper that way..

Newton was wrong? :-)
