Responded to a service call for a Goodman GSX130361 air conditioner exhibiting intermittent cooling issues. Utilized Fluke 116 HVAC multimeter to diagnose faulty run capacitor. Replaced with a Turbo 200 45+5 MFD 370/440V dual capacitor. Cleaned condenser coils using Diversitech Triple-D coil cleaner to improve heat transfer efficiency. Recharged system with R-410A refrigerant using Fieldpiece SM480V digital manifold. Installed new Honeywell R8285D5001 control center for improved system management. Conducted performance test, verifying proper operation and cooling capacity. Unit now functioning optimally, ensuring consistent comfort and energy efficiency for the homeowner.
