The Furnace Repair She Remembered As Her Best Service Call

from The Human Diagnostic

A woman called me a year after a long, hard furnace repair to thank me, and she described it as the best service she ever had.That visit was a slog. Her furnace died on the coldest week of winter, I had to drive back to the shop for a part, and the whole thing ran hours longer than either of us wanted. By any honest accounting it was a frustrating afternoon.But that is not what she kept. What she kept was the end, when I sat at her kitchen table, drew her a diagram, and told her the furnace had ten good years left. There is a name for why the rough middle vanished and the calm ending stayed. The peak-end rule, from Daniel Kahneman and his colleagues.The middle of a job belongs to me. The end belongs to the customer. So I have learned to slow down right when my tired body wants to speed up, because the last few minutes are the minutes the memory keeps.Core line: "The middle of the job is mine. The end of the job is theirs." Give Us A Shout Thanks for tuning in to Hartzell's Heat & Air, your trusted HVAC experts in Oklahoma and beyond.
