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.

Most commercial kitchen equipment installations require permits: gas appliance permits for any gas connection work, electrical permits for new circuits or panel changes, plumbing permits for water and drain connections, and health department approval for new food service operations or major renovations. Requirements vary by jurisdiction — your installer should know local requirements. Operating without required permits can result in fines and forced closure during inspections.

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.
