Dragonfly Heating & Cooling

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.

A comprehensive PM program should include: scheduled inspections at manufacturer-recommended intervals, cleaning of condenser coils and filters, calibration of temperature controls, inspection and testing of safety systems, lubrication of moving parts, replacement of wear items (gaskets, filters, belts), refrigerant level checks, combustion analysis for gas equipment, and detailed documentation for each visit. Avoid programs that are just a visual inspection without hands-on service.

Oil quality directly affects fryer performance and longevity. Degraded oil causes: higher operating temperatures needed, longer cook times, off-flavors, and increased carbon buildup on heating elements and thermostat probes. Proper oil management includes: filtering daily, testing oil quality with strips or meters, full oil changes based on usage (typically every 1-3 weeks), and cleaning the fryer tank when changing oil. Poor oil management is a leading cause of premature fryer failure.
