See the Rust in the New Overflow Pan? This should not be here. Just a little more insulation on the exposed refrigeration line would have prevented the condensation drip. This is just the small amount of condensation that will not go into the overflow line and drip outside. This type of small drip over a period of time will rust through the condensation pan and start dripping on the ceiling. For this reason it is Very Important to have your HVAC system Routinely inspected and Serviced. We catch these small issues before they become Large Disasters!
