AC Troubleshooting Low Superheat

I am testing a new ac condenser. I noticed that the suction pressure and suction pipe temperature are low. The suction pipe temperature drops down to low 30°s which is close to freezing up. Therefore I go inside to verify, airflow. I noticed that both filters are plugged. Once I pull the dirty filters out of the system the suction pipe starts warming up. The Evaporator gaining heat causes the refrigerant to boil off and superheat back into a vapor. The system Superheat rises up to 16°. This video shows how low airflow from dirty filter affects an air-conditioning system operation. Low Superheat means that liquid refrigerant is flooding back to the compressor. The compressor supposed to pump gas or vapor only.
