One system A/C tune-up completed. Changed the filter. Found heavy amounts of mold. The system needs a UV light to get rid of the mold. The blower wheel is very dirty. Recommended a blower wheel cleaning. Found the blower capacitor to be weak. Recommended repairing it. The main electrical switch in the condenser is burnt. Recommended repairing it. The system pulling high amps. Recommended a hard start kit to reduce the load on the compressor. Chemically washed the condenser coil. The system is cooling at this time.
