I performed routine maintenance on a Coleman air conditioning system. The unit was running smoothly with no performance issues. The refrigerant levels were checked and were within the optimal range, indicating that the system was properly charged and cooling effectively. The air filter was clean and allowing for proper airflow throughout the system. All electrical components, including the capacitor, contactor, and wiring, were inspected and tested, and everything was in excellent condition. Overall, the system was clean, efficient, and operating at peak performance.
