Ten Good Things and One Bad One: What Her Brain Kept From the Repair
She had the door open before I got to the porch, and the first thing out of her mouth was an apology for her return duct. Late September, the first real cold front of the fall through Kingfisher County. The wind swings around to the north after supper and half the town reaches for the thermostat and slides it to heat for the first time since April. Brick ranch on a section line west of town, built in the eighties, a few acres, a shop out back. The homeowner is a retired schoolteacher, widowed a while now, a customer of mine going on eleven years. The furnace wouldn't light. Blower ran, no heat, then it shut itself down and tried again. The most ordinary call there is on a night like that. I have been in that house ten times. Every one of those visits ended fine. Tune-ups, a capacitor, a thermostat she picked out herself, a drain line one wet spring. Ten times, and she always has coffee going. And the thing she led with, before hello, was, "Now don't say anything about that return. Your man already told me about it." Your man. A tech who worked for me about two years and left to go work on pipelines, eight years ago if it's a day. What he did, best I can piece together, was stand in her utility closet with a flashlight, look at the return her late husband had built out of sheet metal and a good idea, and say, mostly to himself, "Who installed this?" That's it. Three words, not even aimed at her. He fixed what he came to fix. She paid. By every measure I keep, that was a good visit. Nine good visits since. And she opens the door with those three words. I went in, got the panel off, and found a cracked hot surface igniter, which is about the most common thing that can go wrong on the first cold night of the year. And while I was in there with the flashlight, looking at the low-voltage wire somebody had run to that thermostat, I said, "Huh." Core line: "I told her the igniter was the most ordinary part I replace every fall, that her husband's return had done its job for thirty years, and that I was sorry about the "huh."
