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?”
Bob and Tim were at a retail store where the manager had called and said there was no cooling. The system was a 5-ton heat pump. After talking to the manager, Bob and Tim turned the thermostat to the “fan on” position to see if there was power to the unit and the indoor fan started. The heat pump was a split system, so they went up to the roof.
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.
Bob and Tim were at a no cooling call, the first of the year. They turned the thermostat to cooling and put it on a low setting so the heat pump would come on and stay on.

Bob and Tim were on their way to a no heat call for a gas furnace. Tim asked, “What do you think we need to look out for on this call?” Bob said, “It could be any number of things. We will start by talking to the homeowner and see what she knows.”
