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.

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.

Commercial oven repair costs range from $200 to $2,000+ depending on the issue. Common repairs: igniter replacement $200-$400, thermostat or temperature probe $250-$500, gas valve replacement $350-$700, control board $600-$1,500, heating element (electric) $200-$600. Diagnostic fees of $100-$200 are typically applied to the repair total.
