Note: Before we get into the details of this particular situation, we want to point out that there are actually three questions to answer.
In this month’s troubleshooting problem, the equipment is a split system that’s approximately 8 years old, consisting of a gas furnace that provides heat in the winter, and employs a condensing unit and “A” coil to provide summer cooling. The information you get from the dispatcher is that the customer’s complaint is that the system is not cooling and the specific information they provide is that the unit is “blowing warm air.”
