7474* door code next to outdoor unit. Tech found aux drain pan on opposite side of drain trap to be full of water. There was some algae in trap, but not much. Tech suspects drain trap did not clog. Tech found condensate spilling out the back side of air handler. Left side from attic scuttle hole. Tech used isolator pads to raise the back of the primary drain pan to get water draining downhill to drain exit of air handler. Pumped the majority of water out of both aux pans and tested drainage with water. Couldn’t reach last few inches of water with transfer pump hose. Both float switches reset. System is back cooling. Allowed system to run several minutes and drain exit started dripping rapidly unassisted. Need to follow up on Monday regarding duct modifications. Duct system is unchanged. Curtis made sure to notate that they want duct system modified as needed to ensure proper airflow. Curtis approved service call and drain cleaning.
