Complete 2 system a/c repair and preventative maintenance check. Cleaned outdoor u it and checked all components. Main floor system Outdoor capacitor is weak and out of manufacturing spec. Both systems could benefit from a compressor saver hard start. Upstairs system desperately needs a duct cleaning as the ducts are very dirty and the blower wheel is starting to get dirty which will cause it to be unbalanced and cause damage to the motor. Both systems are cooling normal at this time. Replaced main level outdoor dual capacitor
