Ac repair: primary and secondary drain lines are clogged. Drain pan is filling with water. The float switch installed was too high to effectively stop the water dripping over the edge of the pan. Recommend clearing drain line and drain pan and setting the float switch lower. Also recommend signing up for the comfort club membership for twice annual maintenance to help keep the drain lines as clear as possible. Drain line is clear and draining normally at this time. Poured 1 gallon of water down the primary drain line and no water backups formed.
