Upon my arrival in Elgin I did AC Service. I spoke with the customer about their concerns with the system not cooling. Performing my diagnostics I found that the emergency drain pan was full of water due to the primary drain line being broken at the system. The water removal was backed up. There is not proof on the line got broken so I charged for clearing the water removal system today and fixed the drain line as well. I cleared the water removal system then stress tested the primary pan to verify it did not have any cracks. There were no signs of any cracks on the drain pan at this time. I also made corrections to the comfort control for the customer so it would no longer try to run a schedule and the back like stays illuminated at all times. System is working properly at this time.
