No, you should never pour hot water, boiling water, or use direct open flames and heat guns to thaw a frozen air conditioner unit. Pouring hot water onto frozen indoor evaporator coils or outdoor components creates an extreme thermal shock hazard that can crack fragile copper refrigerant lines, warp aluminum fins, and damage the structural housing of the equipment. Furthermore, melting the ice rapidly without addressing the underlying airflow restriction or low refrigerant charge will simply cause the system to freeze up solid again within hours. Instead, always allow the ice to melt naturally by turning the cooling off and running the blower fan. Verification: Let the system thaw safely over several hours without applying artificial heat sources.
