The correct answer highlights the importance of proactive maintenance for air conditioning systems in vehicles. A/C system components should be replaced when there are visible indicators of wear, failure, or damage which compromise the efficiency or performance of the system. Components in an A/C system, such as the compressor, condenser, evaporator, or hoses, can gradually degrade over time, and early detection of issues can prevent more costly repairs down the line.

Timely replacement of these parts ensures that the air conditioning system operates at peak efficiency, providing adequate cooling and maintaining overall vehicle comfort. It also helps prevent potential breakdowns that could leave the system inoperative, which emphasizes the value of addressing issues before they lead to total system failure.

In contrast, waiting until the A/C system completely stops working not only risks passenger comfort but can also lead to extensive damage that might require more complex and expensive repairs. Similarly, adhering to a routine timeline for replacements, such as every five years, disregards the unique conditions and usage patterns that affect different vehicles, meaning components may wear differently based on environment and usage. Lastly, addressing customer complaints after the fact, without proactive checks and maintenance, might result in unnecessary downtime or more costly repairs, underscoring the proactive approach indicated in the correct answer
