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.

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.

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.
