Performed AC diagnostic on Evcon system. Upon my diagnostic I found that the primary drain line had been clogged that is piped outside. This drain line is responsible for the draining of condensation of the evaporator coil. I proceeded to cut the half inch PVC line in vacuum out and run dry nitrogen through to clear any restrictions. Also went under house and took apart Flex hose connecting to PVC and cleared all restrictions within that hose system is flowing and draining properly at this moment and refrigerant pressures look fine, All the low-voltage wiring was chewed up a bit by rodents respliced it looks good now. Upon departure system is fully operational and cooling.
