Lozier Heating & Cooling

Commercial kitchen equipment lifespans vary: commercial ovens 15-20 years, fryers 10-15 years, refrigeration equipment 10-15 years, ice machines 7-10 years, dishwashers 10-15 years, steam tables 10-15 years. Regular preventive maintenance significantly extends equipment life. Equipment that is properly maintained often outlasts these averages by 5+ years.

Preventive maintenance frequency depends on the equipment and usage volume. As a general guideline: fryers and ovens should be inspected every 3-6 months; refrigeration equipment annually or semi-annually; ice machines every 6 months (including cleaning and sanitizing); exhaust hoods quarterly to semi-annually per NFPA 96; and dishwashers quarterly. High-volume operations benefit from more frequent service intervals.

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.
