No cooling, thermostat to displaying a fan fault error code. Went up into the attic where air handler is located and found emergency drain pan full of water. Drain line is plugged and primary float switch is bad. Also condenser coil is dirty. Gave client solutions for issues with system. Client chose to move forward with all repairs. Removed all water from emergency drain pan, installed an in-line drain cleaner to break down any sediment buildup in drain line, cleaned and flushed out drain line, and chemically cleaned condenser coil. Start and tested system, all operations OK at this time.
