Arrived at customer's house for no cool. On arrival customer showed me to air handler unit. Condensate pipe had come loose from unit. Gave customer price to repair and customers agreed. Installed new male PVC fitting fitting and new section of condensate line. Sucked out drain line. Unit now running. Giving acceptable delta T. Told customers I am not extremely confident in female futting on drain pan.. appears to have been cross threaded in past. Collected payment and signature for today's work and left. Customers happy.
