Inspection Findings: During the service visit, the air conditioning system was found to be low on refrigerant charge. Upon inspecting the evaporator coil, traces of refrigerant oil were observed, which is a strong indicator of a potential refrigerant leak at or near the evaporator coil. If the customer wishes to proceed, a comprehensive leak detection test (using dye, electronic detector, or pressure test methods) can be performed to verify the source 100%. Due to the unknown duration the system has been operating while low on refrigerant, it is not possible to determine whether the compressor has sustained internal damage at this time. Professional Recommendation: Considering the age of the equipment, the low refrigerant condition, the suspected coil leak, and the potential risk to the compressor, it is recommended to replace the entire A/C system to ensure reliable and efficient operation going forward.
