Debate: Do you fix in place or pull and bench test first?
I got called to a house on Tuesday, washer wouldn't drain. Found a sock jammed in the pump, easy fix. But the homeowner kept asking why I didn't take the whole machine apart on site. I've always believed in fixing what's broken right there, keeps the job quick and the customer happy. But my buddy swears by pulling the unit to his truck and testing everything on a bench. He says he catches more hidden issues that way. Which camp are you in? Does bench testing really save you a callback or is it just extra work?
