The equipment in this month’s troubleshooting problem is an electric furnace that has been in service for at least ten years and has no service history.
In this troubleshooting situation, a restaurant manger is calling for service on a reach-in freezer, and the complaint is that the unit “isn’t freezing things hard.”
In this month’s troubleshooting situation, the equipment that needs servicing is a split system and the refrigerant flow control is handled via an EEV.
Our troubleshooting problem involves a complaint from a customer who is concerned that their electric furnace is running excessively and wasting energy.
