Tech did not have materials to make repairs as shown in photos from customer. Did not charge customer as there was no diagnosis needed beyond the information provided by the customer before tech arrived on site. Metal duct trunk line needs to be re-insulated completely. Current insulation is saturated and cannot be repaired. Advised customer that we will contact them on Monday with quote to replace insulation. System is 2006, R22. Customer stated the system has been recharged several times over the past years. Tech offered to do a system operations test and customer declined. PVC drain line also needs to be insulated.
