Commercial restaurant refrigerators typically last 10 to 15 years, with proper maintenance potentially extending their lifespan to 20 years. Factors affecting longevity include: Quality of the unit: Higher-end models often last longer. Maintenance frequency: Regular servicing can significantly extend operational life. Usage patterns: Heavy use in busy kitchens may shorten lifespan. Environmental conditions: Extreme temperatures or humidity can impact performance. Technological advancements: Newer, more efficient models may make replacement cost-effective before the end of the unit’s physical life. To maximize lifespan, schedule regular professional maintenance, clean condenser coils frequently, and address minor issues promptly.
