Bob receives a call from the dispatcher that the basement in a large home is flooded and the owner thinks it has something to do with the air conditioner. When Bob drives up in the driveway, the homeowner meets him at his truck and says, "There is a lot of water in the basement and it seems to be coming from the air handler that is located in a closet in the basement."
Bob has never done work for this customer, so he asks the owner to take him to the place where he thinks the water is coming from.
