I was Dispatched to a noisy System Call. Upon arrival I found the Compressor to be defective. I attempted to make temporary repairs by replacing the Dual Run Capacitor and Hard Start Kit. This did not work. The Compressor is Defective. The System is a 15-year old 4-ton R-22 Goodman A/C Condenser with a York Horizontal Gas Furnace in the Attic.
