If an A/C system component needs servicing, who is correct about the cause of debris?

In an A/C system, the presence of debris can originate from several sources, which is why both Service Consultant A and Service Consultant B can be considered correct.

Debris in an A/C system typically comes from several potential issues, such as the wear and tear of components, corrosion, or breakdown of lubricants. For instance, when seals degrade over time, they can release material that contributes to debris accumulation. Additionally, if filters are not regularly maintained or replaced, dust and particles can bypass them, ultimately finding their way into the system.

It is also possible that external contaminants can enter the A/C system if there are any breaches or openings. This reinforces the fact that understanding the possible causes of debris—including both internal failures of components and external contaminants—is crucial for effective servicing and maintenance of the A/C system.

Since both consultants are likely pointing out different but valid sources of debris, it confirms that their observations complement each other, thereby justifying the response that both are correct.
