About
Understanding the problem
Temperature rises during deliveries, slow recovery after closing, or uneven shelf temperatures can point to different operating problems. Door traffic, blocked evaporator airflow, dirty heat-transfer surfaces, failed fans, and control faults need to be separated before a repair is chosen.
What our service assessment covers
Our service approach checks the temperature trend, door closure, evaporator airflow, condensate drainage, and the refrigeration system under its actual operating load. A warm box does not automatically mean it needs refrigerant.
Before you schedule
Record the displayed temperature and an independent reading, the time the rise began, delivery activity, and any ice on the evaporator. Keep air passages clear and follow your facility’s product-protection procedures.
