Neglecting regular checks in preventative maintenance can significantly impact both the cost efficiency of operation and the operational lifespan of the equipment.

When routine inspections and maintenance tasks are overlooked, small issues may escalate into larger, more expensive problems, leading to higher operational costs. For example, if a minor refrigerant leak goes undetected, it can not only decrease the overall efficiency of the system but also lead to increased energy consumption and operating costs. Regular maintenance helps to ensure that the equipment is running at optimal efficiency, which directly influences cost savings.

In addition, regular maintenance is essential for extending the operational lifespan of refrigeration equipment. Scheduled checks allow for the timely replacement of worn-out components, lubrication of moving parts, and cleaning of condenser coils, which help prevent wear and tear. Without these interventions, equipment may fail prematurely due to accumulated damage or undiagnosed issues, resulting in costly breakdowns and replacements.

Therefore, by emphasizing both cost efficiency and operational lifespan, the correct answer recognizes the comprehensive impact of preventative maintenance neglect on refrigeration systems.
