Came out to call. Customer said water was dripping from drain on back porch. I had to check drain and emergency drain pan. System is hard to access, so I had to access it through garage. I vacuumed out drain pan of system. Cleaned out drain, and vacuumed out remaining water. Evaporator coil has a lot of air leaks, and wasn’t sealed off that well. I recommended replacing the coil to get a better fit and less air leaks. The air leaks are also creating moisture. Customer will get back to me about it.
