Why Some Customers Want a Silent AC Repair
from The Human Diagnostic
There is a kind of customer who, when you walk in, does not want a relationship. She is not rude. She is not cold. She has answered the door, shown you the thermostat, pointed at the indoor unit, and now she would like you to do your work and let her go back to whatever she was doing before you got there. Most of the techs I have trained read this customer wrong. They think she is unfriendly. They try to warm her up. She does not want to like them. She wants to read her book. In 1967 Hans Eysenck proposed that introverts and extroverts have different baseline levels of cortical arousal. The introvert's nervous system is already running closer to the top of its range, so additional input, including social input, pushes it past comfortable. Susan Cain's 2012 book Quiet pulled this into a wider conversation and named the cultural bias toward extroversion in American life. I went out to a house in Watonga last fall. A woman in her late forties. The condenser was making a noise. She met me at the door, walked me to the unit, said please tell me what you find, and went back inside to her book. A young tech with me said, that woman does not like us. I said, that woman is fine. She does not want a conversation. She wants the noise to stop. I fixed the noise, knocked on the doorframe, gave her the brief summary, and left. The young tech read it as a failed relationship. I read it as a perfect call. She did not need me to be her friend. She needed her air conditioner to work. The relationship she wants is the absence of a demand for a relationship. That is not coldness. That is respect. About a third of customers, by Cain's numbers, are running a different system. They will never tell you to talk less. They are too polite. They will just rate you a four instead of a five and you will not know why. So when I train a young tech I tell him to read the room. Quiet music, half finished book, closed doors, no hovering, and your job is to be the most efficient and least demanding human she has dealt with all week.
