Hartzell's Heat & Air: When a Customer Blames the AC Repair on a Bad Install

I pulled up to a house on a section line road south of Enid on a Wednesday in July. The man was already in the driveway, arms crossed, watching me park. He met me at the truck window before I had the door open and told me whoever put this system in did it wrong, and he wanted to know what I was going to do about it.I had never been to that address. I had not installed the system. I said yes sir, let me take a look.The install was clean. Lineset sized right, electrical right, pad level. What I found was a coil packed with cottonwood and dog hair, a failed capacitor, and refrigerant low from a slow leak nobody had been watching. The original filter was still in it after four years. Nothing had been installed wrong. The system had been ignored.Here is the part that interested me. Nicki Crick and Kenneth Dodge wrote about hostile attribution bias back in 1994. Some people read an ambiguous situation as somebody's fault. When a machine fails, they go looking for a villain who cut corners. You cannot argue a person out of that, because arguing just proves there is something to be hostile about.So I did not start with facts. I asked him to walk me through what he had noticed over two summers, and I let him talk. Then I pulled the original filter out and set it on the kitchen table. A dirty object on the table is harder to argue with than an explanation in the air. He looked at it, and the story started to change.He signed the estimate. The house was cooling by afternoon. He called the next week to say it had never run that well. The villain was time and a dirty filter. That does not make a good story, but it makes a fixable house.Core line: “Things that break feel like someone's fault. It's a natural thing to want a reason.”Give Us A ShoutThanks for tuning in to Hartzell's Heat & Air, your trusted HVAC experts in Oklahoma and beyond.
