Rheem Commercial Rooftop AC Repair – Frozen Evaporator Coil & R-410A Refrigerant Recharge – Scholz Garten, Austin, TX 11.02.26
Setpoint Services performed commercial rooftop air conditioning repairs at Scholz Garten, also known as Scholz Beer Garden, in downtown Austin, Texas, after the restaurant reported that its kitchen air conditioning system was not cooling properly and might be frozen over.
Our technician inspected the Rheem RLKL-B120CL000 rooftop HVAC unit, which operates on R-410A refrigerant, and confirmed significant ice accumulation on the evaporator coil. The system was turned off upon arrival.
The accumulated ice was removed from the evaporator coil, the condensate drain line was cleaned, and the outdoor condenser coil was thoroughly cleaned to improve airflow and heat transfer.
Refrigeration diagnostics revealed initial operating pressures of approximately 105 PSIG suction and 293 PSIG discharge. The system was found slightly low on refrigerant, requiring the addition of 1.5 pounds of R-410A to improve cooling performance.
Following the cleaning and refrigerant adjustment, operating pressures stabilized at approximately 115 PSIG suction and 320 PSIG discharge. The rooftop air conditioning unit was restarted and monitored to verify proper operation.
The Rheem commercial kitchen rooftop AC system was operating normally and cooling properly before our technician departed. Continued monitoring was recommended to identify any recurring evaporator icing or refrigerant loss. This repair helped restore dependable kitchen air conditioning at Scholz Garten in Austin, Texas.
