Bob and Tim were at the house of a customer who said that her air conditioning unit did not cool well in the hot weather three days ago. She said the unit actually froze up and had ice on the outdoor portion of the unit on the big line. She shut the unit off and called for service.
Bob and Tim had just arrived at the house of a new customer who explained that the air conditioning system was not working. The homeowner said that they had just had a warm day and the air conditioning system did not come on when they tried to cool the house down yesterday.
In this troubleshooting situation, the equipment is a split system that’s approximately five years old, consisting of a gas furnace to provide heat in the winter, and a condensing unit and “A” coil to provide summer cooling. There are actually three questions to answer in this problem.
Humans simply can’t absorb new processes as fast as they become available. And newer recruits have even less time to learn old procedures and new techniques at the same time. Machines, however, have that capability.
Bob and Tim were on their way to the shop on a hot Friday afternoon when Bob got a call on his cell phone from his wife who said, “The air conditioner is not working and my mom and dad are coming from out of town tonight. What are we going to do?”
A new customer called and wanted their commercial unit serviced. The customer was a retail store and the manager seemed to think that the unit was not performing up to standard. The unit would run most of the time, even in mild weather, and did not seem to cool the store as well as it should.
