Drain pan was full of water upon arrival causing the float switch to trip. Drain line was clogged at the evaporator coil drain pan, causing water to overflow through the system. Cleared drain clog and water out of drain pan and added pan treatment to system. After doing the work the system was cooling with a temperature split of 22° (72 R - 50 S). System is draining properly and condensate pump is allowing water to pump properly.
