Bob and Tim were on their way to a service contract routine procedure when the dispatcher called and asked them to go to a residence that had no heat and had a very sick family member. They needed heat as quickly as possible.
In this month’s troubleshooting situation, we’re taking you to a school, but not to the equipment room of the main building. Instead, it’s a modular classroom (similar to a double-wide manufactured home) that is brand new, and employs a heating/cooling unit that mounts on one end of the building.
Bob and Tim were on their way to a “low heat” call at a residence when the dispatcher called them back and told them that the homeowner had called and explained that the furnace was hot, but the home was cold. The dispatcher had told the owner to shut the furnace off until Bob and Tim arrived.

Bob and Tim arrived at their fifth service call of the day. They were both wet from servicing a heat pump outdoor unit in the snow. This was a no heat call for a gas furnace. The weather was cold and there was no heat at all in the house.

Bob and Tim have gotten together after work to discuss the oil furnace service call that they were on earlier in the day. Bob had asked Tim if he would be willing to stay after work and review the call and Tim readily agreed.

Bob and Tim were on their way to a no heat call. It was an oil heat application and Tim was anxious to work on an oil system. He had not seen an actual oil heat installation, only in the school lab. Those are great, but not like the real thing at a customer’s house.
In this month’s troubleshooting problem we have a customer who can only tell us that their heat pump “isn’t working” and “the temperature in the building isn’t right.” When you arrive, you confirm the system isn’t operating properly. The indoor fan motor is running normally, but the building temperature is far from the thermostat set-point.
