Bob and Tim are looking at a system that has a frozen evaporator coil. The system is in a home. They are talking about what has happened to the system and what to do about it.
“What could be the cause of this freeze up?” Tim asked. “The whole evaporator is frozen, the suction line is frozen out to the condenser, the compressor has a block of ice on the side of it, and it is 90 degrees out here.”
