Upon arrival I found the customer’s secondary pan had been filling up with water since the end of July. We were just out at the end of July for the same thing and the customers had to empty the drain pan twice since. After further inspecting the system, I found where the primary drain line comes out of the air handler cabinet. It had popped out of the coupling and was draining out of the armor flex directly into the secondary pan. I was able to get the drain back in the coupling. I flushed the drain line and then let the system run until it started draining. Your system is cooling/draining properly at this time
