True Commercial Refrigeration Repair – Austin, TX 07.30.26
Setpoint Services completed comprehensive commercial refrigeration and HVAC preventive maintenance at Lake Austin Marina in Austin, Texas. Preventative maintenance was performed on multiple reach-in coolers, Mitsubishi mini-split air conditioning systems, and Polar Temp outdoor ice box refrigeration units to improve reliability, cooling performance, and energy efficiency.
As part of the refrigeration maintenance program, all reach-in cooler media filters were replaced, condensate drain lines were cleared, and each unit was inspected to verify proper cooling operation and temperature performance. A service call was also completed on a True Refrigeration reach-in cooler after the customer reported poor cooling performance and water accumulation. Refrigerant operating pressures were tested and found to be within normal operating specifications. Further inspection determined the cooler was operating correctly, with excessive product loading restricting evaporator airflow and contributing to condensation. Recommendations were provided to improve airflow by reducing product blockage around the evaporator section.
Preventive maintenance was also completed on two Mitsubishi Electric mini-split systems. Both outdoor condenser coils were chemically cleaned to restore proper airflow and improve heat transfer. System operation was verified after cleaning, and both units were producing approximately a 20°F temperature differential, confirming normal cooling performance.
In addition, preventive maintenance was performed on two Polar Temp outdoor ice box refrigeration systems. Both condenser coils were chemically cleaned, with the parking lot ice box found heavily restricted by dirt, leaves, and debris that significantly reduced condenser airflow. After cleaning, condenser performance improved substantially, allowing both ice box refrigeration systems to return to below-freezing operating temperatures. Regular condenser coil cleaning helps reduce compressor stress, improve energy efficiency, and prevent costly refrigeration breakdowns during peak summer conditions.
