Customer says ac works well in the morning but by afternoon it runs constantly and does not put out cool air. They haven’t ran the ac in about 2 days Turned on condenser and confirmed it turned on with both fan motor and compressor running. Checked filter, customer says he has a 2 inch filter tray and because a single filter will slap up and down when it turns off and on that he puts two filters in the filter tray. I explained to him why this is bad and this issues it can cause with that system. The two filters were removed, the outer filter was slightly dirty. Checked refrigerant levels and they were fine Suction: 130 Liquid: 540 V sat: 44.2 After verifying refrigerant levels were good and removing the dual filters I took a temperature split and the unit was performing optimally Return temperature: 80 degrees Supply temperature: 61 degrees Explained to customer that this double filtering was cutting of airflow, this lack of airflow would cause the ac coil to freeze up which
