Trane Commercial HVAC Service – Hutto, TX 07.24.26
Setpoint Services completed a commercial rooftop air conditioning compressor replacement and refrigeration system repair at Smoothie King Hutto, located at 2098 Muirfield Bend Dr, Hutto, TX 78634. The Trane rooftop unit was found with a failed Copeland compressor that would briefly attempt to start before shutting down, despite receiving proper three-phase line voltage. Further inspection revealed severely restricted airflow caused by heavily clogged return-air grilles and a condenser coil packed with dirt and debris, conditions that likely contributed to compressor overheating and premature failure. A significant amount of refrigerant oil was also found throughout the compressor compartment and condenser section, indicating the presence of a refrigerant leak.
The repair included replacing the failed compressor, compressor contactor, and liquid-line filter drier. During the repair, Setpoint Services inspected the refrigeration system for the source of the refrigerant leak and repaired any accessible leak discovered within the scope of the quoted work. The improperly identified three-phase power wiring was also traced and corrected to verify proper phase sequence and compressor rotation. The condenser coil and return-air grilles were thoroughly cleaned to restore proper airflow and improve system efficiency.
After completing the mechanical repairs, the refrigeration circuit was pressure-tested with nitrogen, evacuated to a deep vacuum, and recharged with up to 7 pounds of virgin R-410A refrigerant. The rooftop air conditioning system was then restarted and tested to verify proper compressor operation, refrigerant pressures, electrical performance, airflow, and cooling capacity. This repair also includes a five-year extended compressor warranty, providing long-term protection for the replacement compressor. Any concealed, inaccessible, or additional refrigerant leaks beyond the scope of the quoted repair would require separate customer authorization if discovered.
