Completed an AC repair on a 5-ton split system that wasn’t cooling properly. Diagnosed a failed dual-run capacitor and signs of low refrigerant. Replaced the capacitor, pressure-tested the system, and added R-410A to manufacturer specifications. Checked subcooling and superheat to ensure optimal performance. Cleaned the condenser coil and verified proper airflow across the evaporator. System is now running efficiently with strong airflow and consistent cooling. Customer noticed an immediate difference. Another reliable repair done right to keep things cool and comfortable.
