CFESA (Commercial Food Equipment Service Association) certification is the industry standard for commercial kitchen equipment technicians. Certified technicians have passed rigorous examinations on electrical, refrigeration, and gas systems. When you hire a CFESA-certified tech, you can trust they have the knowledge to properly diagnose and repair commercial kitchen equipment safely and effectively.

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.

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.
