As I noted last time, the first order of business on Saturday was to install the air conditioners. Last year I finally solved the problem of providing fresh air to a room whose sole window was being used to house an air conditioner. To do this I fashioned a retainer to hold the a/c in place while allowing me to raise the window. Unfortunately, the lovely hardwood faced interior grade plywood I used to fashion the retainer didn't stand up well to four months exposure to the great outdoors. As you can see in the photo, the outer veneer is cracked and peeling, and the piece had bowed outward from the pressure exerted by the weight of the a/c. Clearly I needed something better suited to the task.
I replaced it with a new retainer made from 3/4" square aluminum channel, the remnant of which is sitting atop the old support. Took about ten minutes of work with a hack saw and a miter box. Aluminum is very easy to cut. I cleaned up the sharp edges with a file it was all set. Not only should it be much more structurally sound stronger than the original, but it's also an inch shorter, making it much easier to fit and adjust the screen that goes on top of it when the window is open.
And since today was much nicer and less muggy than yesterday, the a/c got turned off again first thing in the morning, and the window was opened.
