The Homeowner Who Spent Two Days Fixing His Own AC

I got a call last August from a house on the north edge of Okarche. The man had been working on his own central air for two days. He told me on the phone he was almost done. He just needed me to come verify a couple of things and maybe top off the refrigerant. He figured thirty minutes. When I pulled up, the capacitor was sitting on top of the unit wired backwards, the contactor he had bought was the wrong amperage, and the thermostat wiring was pulled out and taped together in a ball. It was a hundred and four degrees. He met me in the driveway holding a multimeter he did not know how to read, and he said, well, I have done most of the work, so this should be quick. He knew the words. Capacitor. Contactor. Low voltage side. He had picked them up from the videos. He did not know what they meant. He thought knowing the words was the same as knowing the thing. That gap has a name. David Dunning and Justin Kruger described it in 1999. The same skill you need to do a job well is the skill you need to recognize when you have not done it well. So the less a person knows, the easier it is for them to believe they have it handled. I fixed the system. I billed him fair. When I was loading the truck he told me the videos made it look so easy. He was right. The videos are filmed by people who have done the work a thousand times, edited down to the clean version, and the viewer mistakes that clean version for the skill underneath it. I do not hold it against anybody. The not knowing what you do not know is not a character flaw. It is what happens before you know. That is what forty-seven years has taught me about the people who are two hours into a two-day problem. Core line: "The not knowing what you do not know is not a moral failure. It is what happens before you know." Give Us A Shout Thanks for tuning in to Hartzell's Heat & Air, HVAC in Kingfisher and central Oklahoma.
