Responded to no heat call at residence with furnace completely non-operational. Diagnostic inspection revealed multiple critical component failures in aging heating system, including failed blower motor, compromised burners, defective inducer motor, and faulty igniter. While heat exchanger appears currently serviceable, extensive deterioration and corrosion were documented throughout the system. Due to the age of equipment and multiple component failures, recommended full system replacement rather than extensive repairs. Customer opted to schedule consultation for replacement options.
