AC maintenance and inspection. Upon inspection found capacitor to be low on both the fan and compressor side, after discussing with customer replaced with new call to prevent failure during summer. AC is cooling well at this time and refrigerant levels are good. Compressor makes rattling noise when de-energized at times, does not sound like an urgent issue but it is beginning to show signs of its age. Unit is over 10 years old so a compressor swap is not a recommended fix due to cost of repair opposed to a new system. Other than the rattling noise everything is working well.
