Yes — most food service operators find PM contracts reduce total repair costs by 30-50% compared to reactive-only maintenance. Benefits include: reduced emergency repair calls (the most expensive type), extended equipment lifespan, maintained food safety compliance, priority scheduling for PM customers, and detailed maintenance records for health inspections. The ROI is especially strong for high-volume operations where any downtime is costly.

Signs your oven needs calibration: food is consistently undercooked or overcooked at standard settings, cooking times are significantly longer or shorter than expected, the displayed temperature doesn't match an independent thermometer reading. Oven calibration should be part of every service visit and can drift over time from component wear. A variance of more than 25°F warrants professional calibration.

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.
