Tito · May 18, 2026 · 410 W Main St, Round Rock, TX 78664

Performed commercial refrigeration diagnostic and repair service on a Heatcraft walk-in cooler refrigeration system in Round Rock TX.
Equipment serviced:
Heatcraft Evaporator Model: ADT130AEK
Copeland Compressor Model: ZS13KAE-PFV-118
Customer reported cooling concerns and operational issues with the walk-in cooler system. During inspection, the condenser coil was found heavily clogged, restricting airflow and reducing refrigeration efficiency. Drain line was also clogged with debris and required clearing to restore proper condensate drainage.
Additional inspection revealed the refrigeration system was not configured as a proper pump-down system. No defrost clock or liquid line solenoid valve was installed on the system. Previous installation practices were also identified, including undersized thermostat wiring being used to carry 24V control voltage and cycle the refrigeration system.
Services performed:
Thorough condenser coil cleaning
Cleared clogged condensate drain line
Checked refrigerant pressures and system performance
Verified sight glass condition
Evaluated evaporator and compressor operation
Recorded operating conditions:
Approximately 110°F discharge saturation temperature
Approximately 20°–25°F suction saturation temperature
Full sight glass observed during operation
After service, the walk-in cooler was operating properly and box temperature was reduced below 40°F prior to departure.
Recommendations discussed with customer:
Install defrost clock
Install liquid line solenoid valve
Convert system into proper pump-down configuration
Replace digital thermostat with mechanical thermostat for improved reliability and control
