Emergency repair typically costs 1.5-2.5x normal rates. After-hours service calls usually run $150-$300 for the diagnostic fee, plus parts and labor. Weekend and holiday rates can be higher. However, the cost of downtime — lost revenue, food waste, and staff idle time — almost always exceeds the emergency service premium. Most providers charge $100-$200 diagnostic fees that apply to the total repair.

1) Check if the condenser unit is running. 2) Inspect condenser coils for dirt and debris — blocked coils are a common cause. 3) Ensure walk-in door gaskets are sealing properly. 4) Check if evaporator fan is running. 5) Look for ice buildup on evaporator coils (defrost system failure). If temperature is rising significantly, move temperature-sensitive inventory and call a technician immediately — this is an emergency situation.

Reduced ice production is usually caused by: mineral scale buildup on evaporator plates reducing heat transfer, dirty condenser coils reducing refrigeration efficiency, warm ambient temperature in the equipment room, low refrigerant levels, or water flow problems. The fix for scale buildup is professional cleaning and descaling. Other issues require a technician. Never ignore reduced production — it often progresses to complete failure.
