Diagnostics
Common failures and what they mean
Ice on the evaporator coil
Defrost failure, door left open, or a failed fan. Ice on the coil blocks airflow and leads to compressor damage if ignored.
Compressor running hot and cycling on overload
Dirty condenser, low airflow around the condensing unit or a refrigerant issue. Common on rooftop and back-of-house units.
Water on the floor around the box
Blocked drain lines, failed drain heaters or condensate pans. A slip hazard and a health inspection issue.
