What could be a sign of an improperly sized system?

Frequent breakdowns can be a clear indicator of an improperly sized system. When a system is not adequately sized for the demands placed upon it, it may work harder than necessary to meet those demands, leading to increased wear and tear. This stress on the components can result in breakdowns and malfunctions, necessitating repairs and downtime.

In contrast, consistent operation, high energy efficiency, and minimal maintenance are typically characteristics associated with well-sized and properly functioning systems. A well-sized system operates smoothly without strain, is likely to be more energy-efficient since it's not overworking to meet demands, and generally requires less maintenance because it's not subjected to the excessive stress that could lead to component failure.
