Customer requested tuneup with Ameren rebate. cleaned & checked A/C & performed Ameren post data efficiency analysis. Blower wheel very dirty. I removed and cleaned blower assembly. Also evaporator coil dirty and fins deteriorating. Coil is too fragile to clean properly. Test capacitors. Found blower run capacitor weak: 18%low. Replaced capacitor and tested amp draw.
