 You don't want to have any more of that going out because the air that you bring in, like if you're running laundry, for instance, and it's pulling air in because the dryer's pushing air out, that air is going to be much hotter. So those are the times you want to do your laundry in the morning. You want to do your dishes. And if you're going to do any baking, do it that time in the morning so you keep the heat in. And when you're outside, even though it's hot outside, it's probably going to be more comfortable barbecuing outside on those hot days than it is getting that oven or cooktop going.
