Sub Zero Repair Pros

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.

Kitchen equipment emergencies include: walk-in cooler/freezer temperature rising (food inventory at risk), gas leak or smell, fire suppression system discharge, electrical sparks or burning smells, complete loss of cooking equipment during service hours, dishwasher failure during a busy shift, or any situation creating an immediate food safety risk. These situations require immediate professional attention and may require temporary closure.

Chemical dispensing problems are typically caused by: clogged or faulty chemical pumps, incorrect dilution ratios, empty chemical containers, broken injection lines, or control board issues. In low-temperature machines, proper chemical concentration is essential for sanitization — test strips should verify concentration after every repair. Many chemical distributors offer free testing; alternatively, a technician can verify and repair the dispensing system.
