Upon arrival i found that the thermostat wasnt powered on After investigating, i found that the overflow switch was triggered due to clog built up in drain line Flush and cleared drain line Tested operation of system and its cooling as should I found that the coil was pretty caked up with dirt and debris and the filter was the same way I recommended coil get a pull and clean to remove the dirt and debris built up for better cooling efficiency and better airflow across the coil
