Arrived on site checked in with Saul, he stated that the drain pan was full of water and overflowing. Inspected the unit, opened up the evaporator side noticed the pan was full. Cleaned out the primary drain and blow nitrogen, a lot of debris came out the p trap, it was clogged. Now the drain is working, inspected the other end of the drain and water was coming out. Repositioned the float switch closer to the corner. Unit is running, no issues to report for now.
