Upon inspection, the system drain was found to be clogged, impeding proper drainage. I carefully cleared the clog to restore functionality. Additionally, the gasket on the overflow pan was leaking, causing water to seep onto the ceiling. Although the customer plans to remodel the kitchen soon, they decided not to address the ceiling issue immediately. I replaced the faulty gasket, ensuring a watertight seal. The system is now cooling efficiently, and the immediate concerns have been resolved.
