Mr. Pierce stated that the unit was losing temperature yesterday. Arrive today and checked the charge on the system. Charge is good. I tested capacitor ‘s. All capacitors were within specifications. Opened up side panel to condenser coil. System was clogged with dirt. This would cause the compressor to shut off temporarily and come back on once it cools down. Once I washed it compressor is quieter system is cooling properly at this time.
