Signs of a refrigerant leak: unit runs but doesn't reach temperature, ice buildup on evaporator coil, hissing or bubbling sounds from refrigerant lines, oily residue near connections or fittings, and higher than normal electricity consumption. Only EPA-certified technicians can legally handle refrigerant. If you suspect a leak, call a technician promptly — operating a refrigerator with low refrigerant damages the compressor.

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.

Hood cleaning costs range from $300 to $1,500+ depending on system size, grease accumulation, and accessibility. Small single-hood systems run $300-$500; larger multi-hood systems or restaurants with heavy cooking can run $700-$1,500. Access issues (long duct runs, high roofs) add cost. Budget for cleaning as a fixed operating expense — it's far less expensive than a grease fire, insurance claims, or health violations.
