Arrived at customers residence and was greeted by customer. And was taken to the hatch to the attic and proceeded to the air handler and inspected primary drain line and found that the drain wasn’t properly glued to the threaded coupling into the drain port.. inspected blower motor and wheel and they are both are dirty.. Found that the plenum box insulation has come away from the box at this time. Inspected drip pan and has light amount of water from customer trying to dry pan and decking. Electrical connections are tight and neat to the components at this time and wire nut connections are tight and neat as well. Cleared condensate drain vinegar an hot water at this time. Started system to ensure drain is not leaking or backing up at this time. And no visual evidence of leaks at this time.. system is running and cooling at this time. Customer stated that he would look over estimates and get back to the office when decision has been made
