Commercial refrigerators must maintain 40°F (4°C) or below for food safety compliance. Walk-in freezers should be at 0°F (-18°C) or below. Many food safety programs require refrigerators to run at 35-38°F for proper margin. If your unit struggles to maintain proper temperature, especially during busy service periods or in hot kitchen environments, call a technician — compressor capacity or refrigerant levels may be the issue.

Installation costs vary widely: single appliance installation $300-$2,000 depending on complexity (simple drop-in vs. gas/electrical connections required); complete kitchen buildout $15,000-$75,000+. Costs include equipment setting, utility connections (gas, electric, water, drain), ventilation hookup, and commissioning. Always get installation quotes separate from equipment costs — some dealers include installation, others charge separately.

Common causes include: faulty igniter or ignition module, failed heating element (electric ovens), thermostat or temperature probe failure, gas valve issues, or clogged burner ports. Start by checking error codes on the control panel if equipped. If the oven lights but doesn't reach temperature, the thermostat or temperature probe is often the culprit. A certified technician can diagnose the root cause quickly.
