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 were on their way to a residence outside of town where the homeowners’ complaint was excess humidity in the house.
