The Heat Pump He Thought He'd Already Outsmarted

I got a call last August from a house on the north edge of Okarche. The owner had been working on his own central air for two days. He told me on the phone that he was almost done. He said he just needed me to come out and verify a couple of things and maybe top off the refrigerant. He thought I would be there about thirty minutes. I asked him what he had been doing for two days. He said he had been replacing the thermostat, the contactor, the capacitor, and what he called the high-voltage relay. He said he had watched the videos. He said he had bought the parts off the internet. He said the system was almost back up. I told him I would be there in an hour. I want to talk about that today. About the customer who is two hours into what is actually a two-day problem and does not know it yet. When I pulled up, the condenser cover was off. The capacitor was sitting on top of the unit, wired backwards. The contactor he had bought was the wrong amperage. The thermostat wiring at the air handler had been pulled out and the wires were taped together in a ball with electrical tape. The breaker was off. He was holding a multimeter he did not know how to read. He met me in the driveway. He was sweating. It was a hundred and four degrees outside. He looked at the truck and said, well, I have done most of the work, so this should be quick. I asked him to walk me through what he had done. He walked me through. He used the right words for some of it. Capacitor. Contactor. Low voltage side. He had picked these up from the videos. He did not know what the words meant. He knew the words. He thought the knowing of the words was the knowing of the thing.
