We just came through our first little heat wave of the summer. I think the temps got into the 90's (F) and the highest overnight low was about 61. My own lack of planning and/or laziness got the better of me and contrived to settle all my errands on the hottest day of that period. Otherwise, we engaged in our usual "chill the house" routine at night with its concomitant annual discussion of what the best way to achieve this task.
I am of the belief that you chill the house fastest by putting the box fans in the window to blow out and exhaust the hot air. Spouse likes to feel the breeze and wants the fan blowing in for cooling effect. I don't prefer this because it cools the one room the fan is blowing in towards but the rest of the house stays warm.
So a few years back, after a stunning (I mean stunning!) demonstration of the cooling effect of two box fans exhausting the house, we compromised. We put one fan in the lee window of the house blowing out and one fan in our bedroom window blowing in. Resident Kid could care less what we do, because no matter what we do during these times, the house is too cold in the morning.*
And perhaps it is. After all, I feel victorious if we get the house down to 65, and one night this week, we kind of overdid it and the house was a frigid 62. Yes, a little excessive. The boon of these shenanigans being that the house rarely goes above 75 as it heats during the day. I revel in the natural air conditioning we reap in this region and that connects us so closely with the diurnal swings of the season.
Occasionally we bemoan the extra vacuuming and dusting that comes with open windows and the pollen season can be annoying, but I can't envision living with an air conditioner separating me from the outdoors at this time of year. The connection is too valuable to let go. Besides, who could miss the opportunity to be awakened by the local deer herd trying to sneak past your window to pillage the garden?
* Which gives me another glorious parental opportunity to exhort Kid to "put on a sweater." In July!
