AC is back up and running. A capacitor and its contacts took a dump. Diagnostic fee and parts & labor = $502.47 with a senior discount. Guy said the contacts were scorched, but he'd seen worse. I figured for the extra bucks, just replace 'em. If it turned out later that they completely fried, it would be another $109 show up fee + the price of the contacts. Might as well get it done right.
Only got up to 77 in the house. I kept the curtains closed to keep the sun out, so it wasn't like it was a sweat box in here. It's 84 outside, so it would have gotten a lot warmer by sundown.
