Finished…

…while waiting for the AC repairman. Yes, our air conditioning died on Saturday in the middle of record breaking high temps. The good news is that it cools off at nights so we’ve been able to keep the house comfortable.
I was told the repairman would arrive at 1 pm. He arrived at 2, and then waited for his apprentice to arrive 10 minutes later. Then he proceeded to train this young man on all things AC for the next 2 hours. It turned out all that was wrong with our system was a $10 blown fuse!
This puzzle saved me.
