17 year old R22 system. Found evaporator coils/compressor completely frozen. Found blower wheel warped, and bracket that holds up blower housing broken causing airflow challenges. Motor bearings are failing as well due to this. Wheel and motor would need replacement at the minimum. Unable to do proper leak search due to frozen coils, but potential for refrigerant leaks are high due to heavily rusted coils/age, and may be contributing to system freezing up only adding further repair costs. Heating components are also heavily rusted. Evaporator coils and condenser coils compacted. System is in overall poor condition. Costly repairs not recommended. Handed over to field supervisor. System is down.
